 Hi, my name is David Lewis. I'm the CEO of NZ, and we are developing an array of tools that will be used to inspect high-resolution displays, specifically micro-LED, QLED, and OLED displays. And we're really excited to be talking to Charbox. And here I'm going to put one of your videos on. It's from your YouTube channel. Can you explain a little bit what's going on? Yes, what we're showing here is one of our original systems over here. This is in a system which is designed specifically for micro-LED inspection. Micro-LED has a few stages before it actually becomes a display. In the mid-range stage, you'll have a wafer. And this wafer will have maybe somewhere between 4 million to 10 million chips. And each one of these chips is going to become part of a pixel for a micro-LED. Each pixel has three chips, blue, red, and green, which gives you color. Though a lot of the devices being made today are still monochromatic in micro-LED. And so our challenge, and the industry's challenge, and where we're coming to help them, is we are taking this wafer. And we look at this wafer over its entirety. And we're trying to identify which ones, single ones, of these millions of chips are defective. And so we do this in a couple of ways. Like we're showing over here, we do a thing called photolubanethan, where we excite with a laser and we see what the spectrum is. There's another way to excite called EL, or electrolubanethan, where you see these two probes are electrically exciting the device in lighting it up. And this is a more accurate way of testing a device, but it's slower than photolubanethan. So these are one of the balances we play with. And one of our developments that we're working on now is to do this in a very fast parallel way. In addition, we make the smallest point of light in the world, nano-optical solutions. And so what you see here is the highest resolution PL available on the market. And this allows us to get the most detail information from a microlet. And we can scan over microlet either in PL or in EL mode. And we get the highest resolution optical emission. And this tells us how the chip is behaving. One of the core measurements which we do for customers is a thing called EQE. And this is really letting us understand how healthy is the chip. If you want to put a chip into a device, you want to know how much electricity is going in and how much light is coming out. And that's the essence of what EQE does, as well as angular measurements. Now, where we come in is microlets have become very, very small. They've become to the level of less than a speck of dust, a single micron, a micron and a half, two microns. And this is especially for applications like augmented reality, where you want to have a very high resolution display, which is very close to your eye. And so you're going to have many, many of these chips turned into pixels in a display, which is right next to your eye. And so to get a very high resolution of 4K or even 8K, you're going to need millions and millions of these chips. And the reason microlet is one of the leading solutions for this technology, for augmented reality technology, is that microlet is much, much brighter than OLED or LCD. And so if you go outside and you have the sun coming out, microlet is the technology which will allow you to still see that information even in daylight. And so there's been a lot of investment in microlet companies. But microlet itself, the manufacturing of microlet today is a big challenge, because microlet manufacturing today is very imperfect. It's very, the yields are very low, meaning that for when you make these wafers, large parts of them, large selections, are not good. And so there's a challenge on one side. How do we identify out of these million chips, which ones are good and which ones are not good? And on the other side, we want to figure out, how do we make it much, much better over time? If you look today on the market, if you look at an LCD, the LCDs are very cheap. And the yields on the LCDs today are 99.99999, five times after the point, percent yield, meaning that it's really practically 100%. If you have 99% yield on a TV, you're talking about hundreds of pixels, which are not going to be good. So it's very important to get to these high yields. And today, the numbers on micro, nobody's coming right out, and it depends on the technology. But I think we can safely say that microlet yields are well below 50%. And so that's a big challenge in terms of making this the devices, like microlet, available to the wide consumer public. And that affects the price of the micro LED, when you don't have a very high yield and if you have to inspect every single one to make sure you're shipping good ones. But is your technology enabling a fast inspection? Our technology is enabling, first and foremost, a much more accurate inspection than what's available today in the market, meaning we're able to see a wide variety of defects which cannot be seen with standard technology. And then secondly, and that's been our main focus until now, has been automating that. We just completed a raise. We just announced it this week. And one of the main focuses of this raise is to allow us to work on our high throughput technologies, both in terms of rapid EL, electro luminescence, rapid PL, and just in generally making the whole process seamlessly fast. Sorry, I was reaching myself. So there are several disruptions that are going to happen that are happening right now with micro LED. And one of them is heads up displays, augmented reality, VR glasses, stuff like that. And so this is going to be huge. And I guess they're getting to insane pixel density, very good brightness. So they work outdoors. And you are totally partnering with all these companies who are sharing those. So obviously I have to be a little careful about who we're working with. I can say we're working with the best companies in the field. And anyone we're not working with yet, we're not saying you're not the best. But we're working with many of the best companies in the field. I think you correctly pointed on that there's a lot of different, there's a convergence of different technologies happening today. Just to take it as a brief example, COVID. All our anybody who had children was home. And thank God for Zoom. I don't know if we didn't have Zoom, we wouldn't have survived this. But even then, it was still very, very complicated as a way to educate. And augmented reality opens up a lot of new channels. And if you look at every big company and a lot of small companies, there's a huge investment in augmented reality. Whether it's Apple, who were one of the first companies to buy a micro-led company, Facebook made a large investment in Plessy, which is a UK-based micro-led company. Google just announced a few weeks ago that they're planning on purchasing Raxiom, I believe for a billion dollars. And so these are all, this shows you that the market and really all, I believe that the main technology driving, pushing these companies towards that investment is augmented reality. And if micro-led is successful, that's the push. For these companies to make such a large investment in this area, I think they need something which they say, OK, what is going to let us do something which nobody else has done until now. It's to make a slightly better TV. I don't think there'd be enough push, even though there's a lot of advantages to micro-led in TVs as well. But I'm confident that if micro-led is successful, in terms of its implementation to AR, then you will see it funnel down into all the other applications. I would say today the two major applications which are going to drive micro-led technology. In my opinion, AR is the big payday, because whoever gets there first and successfully is going to have, everybody sees this as a very important market. And whoever gets there first, this is going to allow them to dominate that market, hopefully. The other area where we're seeing a lot of interest in micro-led or car displays, for a wide variety of whether it's their temperature stability, which makes them much better than OLED in a car. You don't necessarily need the highest resolution, but you need something which can be very bright and very stable, even in high temperatures. And micro-led is a very good candidate for that. So those are on the lower red side, we're seeing car displays on the higher red side. And very high resolution side, like you mentioned, we're seeing augmented reality pushing it very strongly. So I think you're muted. Sorry, I keep muting myself. One market that I'm excited about and I hope it can work in is something like this, where you would have a Pico projector using micro-LED from the phone. Something that's small, very pocketable, because there are these amazing DLP Pico projectors. And there is some technology out there, but it would be nice to have higher resolution, brighter, smaller. I'm not sure what's going to happen with the power consumption, but somehow make it fit smaller. And maybe they're also targeting that. It could be. Also great contrast just to add to your list. I think in term, I think you're 100. I think it's going to open up a wide variety of opportunities. Also, rollable displays, which have not really taken off with OLED, I think they're going to have a wide. With OLED, you have, because it's an organic material and you need to have encapsulation, that creates a variety of challenges. And micro-LED could be better for that. But I think everybody is competing towards this next iPhone or next phone smartphone thing, which everybody has identified now as the augmented reality. And I think that's being a major drive. But again, once that's working and once the pricing has come to a point where people can afford it, I think you'll see a real strong proliferation into the market. And just one thing to highlight about televisions is that you mentioned about power consumption. So power consumption on a TV is not a big issue. But one of the promises of micro-LED is that as the chips become smaller, they'll still be very bright. And so that's why one of the core measurements, which people are trying to do is a thing called external quantum efficiency, which, again, is how much current I put into the device and how much light comes out. And you want that to be very high and consistent. The promise should be that the EQE is around 80%. Today, it's still around 20% or 30% in a lot of devices. And so that's something where for a TV that might be less important, for portable devices, for a battery-powered device that's very important, like augmented reality. And so these are things which still need to be worked. But even on a television, if you have a device and you don't mind putting a lot of power into it, you're still going to get a lot of heating. And so all these issues have to be resolved in order to have an effective device. But one thing I want to say about the television, I think this is a very cool and exciting element of micro-LED is that micro-LED, when it's realized properly, even a small micro-LED will have a lot of power, a lot of brightness. And it will allow you to have a standard pixel size on a television. And so what that means is that you can have basically a standard array for a television. And if you want to go from 42 inch to 55 inch, you're just going to add blocks around it. And that's a big cost saver for the manufacturers, where today, for every different pixel size, you need to have a whole different protocol for setting up the TV. So that's another area where I don't think it's enough to drive the whole market. I don't think that's why these companies are making such a big investment. But I definitely think it's something which is going to have an effect once micro-LED is commercially available. Is it correct that, as I understand, there's two different types of micro-LED? One that kind of looks like it's on the wafer, like a fab style, which what it looks like here. And some other style is more like a mass transfer. Are you compatible with both of these styles, or there's even other ways to make them? So essentially, if you look at the process, you start with a wafer, which is epitaxial wafer, semiconductor wafer. And then you're going to do some etching. And so you're going to do, from our perspective, you do inspection before the etching and after the etching. And after the etching, you have all these devices. Then comes the issue of mass transfer. It's not a separate micro-LED. But basically, at that point, you take the wafer, and you say, OK, now how do we get these devices into a display? And that's why you're probably not going to see micro-LED televisions at an affordable price for a long time, because currently, the cost it takes and the time it takes to transfer millions of devices into a television is not going to make it cost effective. So there's a lot of work being invested into how do we do a mass transfer of these chips from the wafer into the device. That's probably why, in the early stages, we're going to see smaller displays, maybe very high-density displays, but smaller displays, where the cost benefit is still realistic. And when I look here on your video, so it looks like you're talking about 12-inch wafer. So the end, yeah, I'm sorry, go ahead. Yeah, so your customers would buy a bunch of these machines and have a bunch of people in a row like analyzing a bunch of displays at the same time, or? So first of all, I think it's important to, you know, we're working with a few customers already on the 12-inch model. But I think most of the industry today is around the 8-inch level, even maybe 6-inch, depending on the technology. There's a good push to move things towards 12-inch, because that's where the semiconductor world lives. And then when the technology reaches there, there's a lot of tools available which have been already designed for the semiconductor world, as well as reduction in cost, because you're getting much more devices out of each process. So essentially where we are today is we're working more with quality control. And so the tools which you're seeing over here, these are sitting in the labs, they're looking at high-end prototypes. A lot of our focus right now is to make these tools into tools which will sit in the manufacturing plants. We're working on two separate directions. One is a portfolio of inspection tools, including a rapid EL technology. And that will be inspection. Inspection meaning good or not good, is this device appropriate for putting into a display or not. And a second set of tools which are more designed towards defect review, which is, okay, we've identified all the chips which are bad. How do we learn from that process to improve the process which took us until this point, so that the overall yield of the way further, not 50%, but they're in the 90%. And so those are two separate directions which we believe are important areas for the industry. When I look at your video here, you were mentioning, for example, that you have the smallest light in the world. The smallest point of light in the world, the smallest light source. What we're showing now is actually not that, but you'll see that in a few seconds. Our expertise really is in the area of nano-optics. And this was actually discovered by my father, Professor Aaron Lewis, in the 80s when he was in Cornell, and at Cornell University. And what he showed over there is that light can go smaller than the diffraction limit when you confine light to a very small aperture. And that's what we're seeing over here. These are these nano-optical probes which we design. And they can both collect light from a very small, from a very high resolution, a very small aperture, or they can inject light in a very controlled fashion. And what this allows us to do is see in a very precise and accurate way not only is the device emitting light, but how is it emitting light? What is the distribution of light on that device? And that's something which we can show in a very accurate fashion. So if you don't mind, I'll try and share. I'll try and share my screen over here for a second. And just one thing, when I see the video here, it looks like there's two golden blocks next to the pixel. What is that? So that's in every team designed it a little bit differently. But essentially the way these chips are designed on the wafer is that they have electrical contacts. For convenience, we're showing them right next to the chip. Sometimes that's the design. Sometimes you'll see the ground is like a common ground. But essentially people are very interested in seeing the electrical excitation of these chips because in a phone, that's the way they're going to be excited. So you have photo luminescence where we excited optically and then the chip emits light optically. Or we have EL, electro luminescence where we excited electrically and it emits optically. The difference between PL and EL in terms of accuracy of identifying defects can be anywhere between 30 and 40%. So it's considerable. PL though is much faster because there's no contact. EL is a slower process because you're going point by point and you're touching each one and you're turning them on. So it's a much more accurate way of testing the devices but it's unrealistic because of the scale of the way for the micro led. So one of the areas we're putting a lot of effort and focus on is a rapid EL technology which will allow us to do a full way for test every point around 4 million points in about somewhere between half an hour to an hour. And so that's which today would take five to six months if you did every point at two seconds. So we are in a wrap. So that's something we're putting a lot of investment in right now. And do you have a presentation? Maybe you can talk about some slides to explain your technology. Yeah, sure. I think one of the things here, so let me share a slide. One of the things which we can do here is we can use that nano optical probe and we can scan over the device and get a lot of information. So what we're seeing over here is a combination of structural information and optical information. And then we see a combination of that together. So at each point we're getting both the height and how much light is coming out from the device. So one of the core areas of defects in micro leds are what's called sidewall defects. And these are defects which occur from the side of the device. And so we're able to see not only how rough the surface is or if there are any actual structural defects, but actually how much light is coming out in a controlled fashion. And if I go to the next slide over here, you can see here we're looking at an area and we can see how the light varies at different parts in a trench. And we're seeing here with what's called sub diffraction resolution or super resolution, resolution which you can't even get with an optical microscope, how the light is behaving. And so why is this important? We are looking to understand in our process here when a device is behaving not optimally, why is it not behaving optimally? And so one of the things we do is we look for where is the light coming out? And if the light isn't coming out from a specific area, we try and understand what is wrong in the process over there. This could be something structural. We could find thermal defects which are beneath the surface. We can look at changes in material. Most of these wafers are what's called gallium nitride wafers which are three, five semiconductor materials which lead to light emission. And essentially they're grown under great temperature but small variations in the temperature can create changes in wavelength. That's very important to know about displays. What the color is, within two nanometers shifts the color changes in color are not acceptable for high-end displays. And so these are things which we work together with the manufacturers to give them a filtration process going from the full wafer down to the individual chips to identify where are the problems. And once we've identified where the problems are to give them a better understanding of where these problems may be coming from. So they can improve the process and get better and better. So you are involved in the R&D phase right now for the manufacturing of these amazing displays but you're totally planning how to be very relevant and useful in all the mass production. Yeah, I think it's also accurate so that the industry itself is kind of in the R&D phase at this point. There's still, the micro light industry is still, there was a challenge I would say until 2016, 2017. Does micro light really work? Does it exist? Is this a viable technology? Now, everybody agrees it's a viable technology. The question is how do you make it reproducible? How do you make it cost effective? And how do you make it in a consistent fashion? So it doesn't have to, so you get a wide array of devices which perform according to spec. And so right now, in our first two or three years, we interacted first purely R&D. We added automation this year to our core systems and we started working with some big companies on prototyping as well as quality control. But our next stage is to get to full inspection in the manufacturing. Sorry, you muted again. I'm so sorry, I need to stop muting myself. I'm not trying to get any secret information from you but I can imagine that some of these displays are just insanely awesome and very, very futuristic and mind blowing in terms of what they, if this becomes like the next iPhone, let's say if this becomes something that everybody's gonna get, how it's gonna change people's lives, it's very interesting to try to understand. So it's a really awesome field to work in, right? It's a wonderful field to work in and we're very lucky to be working with industry leaders. We are working with them a little bit earlier than the stage of the final screen. We're looking more at the pre-transfer into the screen. But we do get to see some very cool stuff. So we're very lucky. And of course we're very discreet about what we see and don't see. Nice, so this is awesome. And hopefully, I mean it's been talked about for a while and I wonder how many micro-LED displays are shipped yet in the actual products or if everything is... I think you're going to start to see, we're already seeing a few prototypes and I don't think the big challenge of the prototypes because Samsung released the television a year ago at CES and I forget the exact price, but I think with $130,000, maybe for an 80 inch or a 100 inch television. So the prototypes are very important and very critical to showing the capabilities of the technology, to show the maturity of the technology. But then the next stage is to work on the process and bring the process down to a point where everybody can afford it. And we even see this today, if you compare LCD to OLED, again, the LCD has extremely, extremely high yields and OLED has good yields. I don't know, it depends on the application of technology, but let's say they're in the high 90s or mid 90s that you still see there's quite a big price difference between LCD and OLED even so today. So it's an iterative process and I think you have here the combination of a really exciting new technology which is driving it forward. You have a really premium technology which has stood up to the promises which people made about it, meaning very high brightness, very high resolution, great angular distribution. And so there's a lot of push there, but we need to get to some fundamental blocks right now. You mentioned mass transfer inspection and quality assurance is going to be very, very important from a price perspective. And that's where we're looking to really make a difference. I think one of the areas, one area I said we're spending a lot of time and effort on is what's called EQE, external quantum efficiency. And I think today we offer the best if not the premium solution for, I shared the whole screen I think, right? But it's fine. The best if not the, I don't wanna say the only solution but probably one of the only solutions for EQE on an automated mass scale. The other area which we're seeing a lot of interest, EQE tells you how many photons are coming out. But in a display, we don't just care about how many photons are coming out, we care where they're going. So if they're going, 50% of them are going to the side, that's not gonna be great. That's gonna cause you a lot of interference with other chips. So one of the things which people are very interested in is the angular distribution. And this becomes very, very difficult just like EQE to do on devices below 10 microns or even 20 microns. And so this is where we come in with the ability to both have very, very, very accurate angular distribution seeing how the light emits from a device on one hand. And on the other hand, we show here the ability to see how the beam shapes coming from a device. And what this allows us to do is as we start to go farther and farther away from a device, we see what is the optical properties coming out of the device itself. And so these are all very important areas right now for quality control. As we move to inspection, where the focus is going to be, is it a good or bad pixel, a good or bad chip? Then a lot of our, we're gonna have to focus much more on throughput and maybe not on every specific feature. So we're putting a lot of investment within the company also to develop algorithms and filters so we can identify areas which need to be inspected at very high resolution, but ignore areas which seem to be going okay. And so a lot of what we're trying to do is a totally encompassing process of quickly identifying where are the problems, looking at them, identifying what they are, and then moving on to the next one. So these are some of the paths we're working on right now. One thing I can wonder is, like sometimes when, let's say you buy a MacBook, you have one that seems to have a chip that has one of these yields that, where they don't activate all the cores. Is that some kind of way where you get a display that might be a cheaper one, but that's not perfect. And that's still okay. So what, I don't think Apple's the right example for this, but with Indy's devices, there'll be a process which is called binning. And so you're going to look at, you want the blue all to be, let's say, within two nanometers of what we've defined blue to be for this display. If we see a variation of over two nanometers, what different people in the process can do is what's called binning. They can say, okay, we're going to take all the ones below 488 and we're going to 488 nanometers and we're going to put them in a different pile and we'll sell them to the B players. Or for instance, if we see that an area has a lower EQE, then we'll put all those chips in one area together so we don't need to have different voltage excitation, different excitations, different power controls at different parts of the display. So there are all kinds of, you know, it's not just a, you know, there's a lot of room in the middle, go, no, go, it's a big industry and there are many players here. And so, you know, you start to see these, these filterations to different players of different qualities of displays. And I think that's going to have to happen in micro light just to keep the pricing, you know, to make, to get as much bang for your buck, so to speak. Is there a risk that if you have a dead pixel or something in the middle of the display, it's not very nice or is there some kind of way to, because the resolution is so high on some of these crazy little micro LED displays, is it possible, the pixel density, is it possible to just deactivate a bunch of pixels and it doesn't, you can't see it? No, I would say, you know, if that's the worst case scenario, if you've actually have a display and there's like, you know, more than, if there's like a dead pixel in the middle of the display, that display is probably not going to pass quality control. You know, if the, our goal is to catch these defects before they actually get to that final display and to avoid that problem. And I think that's really where the power is the earlier, you know, our power is that we're able to see defects which other people cannot see and we can see them early on. And the earlier on we catch them, the more money that saved for the manufacturers. And so you're saying that it's possible that some of the intensity of the light or the direction of the light might differ slightly. And so it's like, is the yield of the quality getting better and better so they could make billions of these little chips and somehow they're all exactly the same or right now there's a lot of variability? That is the goal, but right now there's a lot of variability. That is the goal, though. The goal is to get it as consistent as possible, you know, as consistent as repeatable as possible. And like any process, I mean, there's a lot of stages in this and it's a complicated, you know, you're going from wafer design, color control, lithography of very small devices. So you have many processes here which all need to be optimized, but eventually they will be and eventually you'll see this, you know, I believe in the next, you know, several years. And your devices are meant to be manually operated. Is there some kind of way to automate this with like computer vision and something? No, so right now, you know, most of our devices are actually automated in terms of, you know, you load up the wafer design. You say, you know, where it identifies where the different chips are and it goes from one to the other, you know, with pattern recognition also it's able to adjust the angle to make sure it's accurate. So that already exists, you know, as we move to the next levels though, we're going to be looking to add more and more AI and big data to identify patterns which are coming from defects, you know, optical patterns. And basically the idea is that every time we see a defect, we want to feed it into the library and create a very large database of these defects so we can identify them earlier and earlier on in the process, also from our process. So we won't need to actually come in with the NanoPro for instance and look at it at that point. So when I look at your device here in the video it looks like there is, at the top, you have to put your eyes in there. There's a person looking through the system, right? It's really more for convenience. Everything is, you know, if you see one of the videos before, you know, everything is shown in the CCD, everything is done through the computer once the wafer is put on. Yeah, if you go to where the EQE is Yeah, keep going. Yeah, I think it's right over there. You'll see a video in a second. So what can you do in terms of the AI and making this even more automated faster? I think, I'm going to give an example from the semiconductor industry and I think this is relevant for what we're talking about as well, you know, in 1985 the first semiconductor chip went below a micron and until there everybody was using standard optical inspection and after that point they started moving more and more to what's called e-beam inspection which is a very high resolution electron microscope to inspect defects. The display industry today is at that inflection point. It's going below, you know, it's going into defects below a micron and that's, you know, that's why you need a very high resolution optical technique which is what we're providing. If you look today at the, at that same industry, you know, if you look at companies like Applied Materials who makes the e-beam tools, they have an optical inspection because that's much faster and then they have an e-beam inspection which is much higher resolution and so we're trying to do a similar direction where we do optical inspection like PL to identify patterns and then identify the defect and create a library which tells us this pattern is this kind of defect, this pattern is not a defect, it's just, you know, some kind of reflection. These are things where the higher, the more statistics we get, the better library it is, the faster the process is going to be, the more efficient the process is going to be. All right, and when I go to your website right here, maybe you can talk a little bit about the company, how many people are you and where are you based? We're going to be 20 people by the end of the year. We're based in Jerusalem and we're sitting in the Technological Park over here which, you know, we're next to Intel, Mobileye, Teva, so we're, you know, we're in great company. We're very lucky to have the former president of Tower Semiconductors join our board and we're very excited about that. We also have Dr. Alan Harris as a senior advisor. He ran a company called Kativa for many years which is a leading OLED inkjet printing company. So we have some really great, great advisors here in the company, great people on the board. My father, Professor Aaron Lewis, is the pioneer of super resolution microscopy. He's really the inventor of super resolution and he's the senior, he's the chief scientist of the company and he's working with us on a lot of the core projects as well. And what did Eric Betzig get the Nobel Prize for? Eric Betzig got a Nobel Prize for super resolution. Eric Betzig shared the Nobel Prize with two other people who showed very important applications of super resolution as a field. So he wanted, if I'm not mistaken, for an area called POM, which is a microscopy area of identifying molecules, single molecules. He also used the technology which my father developed together with Eric, when Eric Betzig was in his lab to show single molecules fluorescence in his work in Bell Labs. But he won his Nobel Prize for his work in super resolution microscopy and he shared it with two other people whose names I don't remember right now. And if I click on the press, so maybe there's the announcement of, so you have like the investment happening? Yes, we just announced the investment on Tuesday. We just closed an investment of $10 million. And this is led by Blue Red Partners, which is a Singapore-based VC, which has a focus on bringing Israeli companies into Asia, which have a large Asian market, also joined by Our Crowd. And our first investors were Maverick Ventures Israel, who really got us started three years ago. And Maverick and Blue Red, as well as the former, Yitzhak Idre, the former president of Tower, are all sitting on the board and they've been great partners in this process. And here it says in the press release that a micro-LED market is going to be 21 billion by 2027. That is what they predict. And I believe that I think by 2027 you'll start to see devices coming out and we expect the field to grow rapidly. All right, so it's an exciting future and to see how this is coming through and it's going to be awesome. So thanks for making these amazing displays work. You're a crucial part of the technology, right? I hope so. I hope so. That's our goal. All right. Cool. Is there something else we forgot to mention in the video?
