 So we had the SID display week right here in Los Angeles at the networking event, and who are you? My name is Yamazaki of semiconductor energy laboratory And so you you worked on Coming up basically with IGSO, right? Yes. Yes, and how many years ago was this? well, we started 20 or 8 and I found that the CAC new structure crystal structure, then we started the big project 2008 2008 so 10 years. Yes 10 years is fast in the display world, right? Yes, but this is a 10 years anniversary for me 10 years anniversary, right? Yes, so Usually some people when they do display technology it takes 50 years before it becomes big and now IGSO is already the biggest Yeah, that is I have the very good 48 the situations first stage for example the sharp cooperate to do the mass production of the crystal and IGSO for the CAC or nano-crystalline Sharp make very beautiful IGSO displays like amazing. They're just so good. They're better than Amofo silicon Yeah, the better that much better than Amofo silicon. Much better quality and power consumption So how much better? How much better? Double as good. Half the power. No The half the power of the power consumption. Half the power? Yeah That is the new function start then I drink soap or something like that Because that of current of the IGSO is so small compared with silicon and This is LCD technology. So LCD is 50 years now, right? Yes, that's correct This year is 50 years anniversary for LCD and you improve LCD so it's better than OLED The backplane backplane at that age that Amofo silicon is used But now the IGSO will change to Amofo silicon then that 8k Biggest 8k spec TV that I think that the IGSO will be the government Dominant technology for 8k. Yes. Yes, and the dominant will be LCD More than OLED for 8k probably One is that 8k of LCD But the other is that OLED application that is more suitable for IGSO So IGSO is okay for OLED? Yeah Absolutely, that's wonderful It's wonderful for OLED. So you're not an LCD only technology? Yeah, I think that In the field of the display the ancient present states that the Amofo silicon and low-temperature poly is governed as a backplane But both of them will change to the IGSO, especially Crystalline IGSO Crystalline IGSO. Yes. So when you say a liquid crystal display and crystalline IGSO, what is its connection? Yeah, different crystal control the backplane and the IGSO will control to to the Which pixel will be bright or black or like that? So that the backplane and the float plane will cooperate with each other And do you have 8k TV at home? Yes, you have one? Yes, in your home At my laboratory, we have. Ah, in your laboratory, not in your home? No, not yet But in the next two years you will have right? I see. Because 2020 Olympics will be 8k Yes, correct. So that we do the correlation with NHK to spread to the 8k spec And IGSO is also better for HDR? Yeah, much much better HDR is spec is 2k So that is 4k and 8k so that much much better the quality I really want to have a 8k 70h sharp display. It looks amazing, right? But it's past 8k dollars It's a little bit expensive. It should be down to 3k, 4k, 2k So so that of course the asset starting the production now go down rapidly I think. And how about all these phones? How many phones are IGSO? How many phones? Smartphones That is now the low-temperature point as a backplane is used But maybe in future in five years that will change to the IGSO Because that the OLED is more suitable for... So right now is which one is used? Is Amofo Silicon now? Now low-temperature point LTPS So now most smartphone is LTPS. Not nobody is making IGSO or somebody a little bit or nobody That is smartphone nobody nobody but iPad The most of all iPads is now produced by using IGSO Nice So if you have 9.7 inch or larger display is suitable, but they will go down to smaller Smaller, not the medium size, not the iPad and then in future that the iPhone less Is there any chance IGSO can be used for reflective display that has no need for backlight? Yeah, that is IGSO is very strong to the flexibility so that we We are the first to satisfy the IGSO as a flexible display We say the foldable display three years ago So you certified for flexible displays, but how about reflective displays the display I can use outside and have the Transflective or reflective or so that we invented the hybrid display that is at the outside that Reflective LCD is used but inside That the OLED You invented that yeah, you also do that. Yeah, this and this is ID we presented the other three Three sections three sections of hybrid display. Yes. Yes, how's the quality of the hybrid? If you go outside with the display, how is it? How will be the quality like paper? Well, no, I'm going to say not so much so that that is one of the problem and to be input To the future. What is the solution to improve this? Because we want to have a display like paper, right? You're working on it, right? You have many projects many things happening Every day in the office, right? Yes for the future also that May I say that another application of the IGSO? Yeah, that is You know that in the age of AI Artificial intelligence. Yeah, do you know that artificial intelligence AI AI? Yeah, that is the power consumption most most important problem For the AI yeah, so that for the application LSI is one of the reason for the high power consumption so that if The silicon LSI may change to IGSO LSI then that power consumption becomes less than one percent But are we talking about processors? No, what are we talking about? After maybe it takes 10 years or like that But the possibility of the IGSO is so high not only to the display. Not only display also CPU CPU and memory CPU and memory will get IGSO also. Yeah, I think five or ten years later So that means the CPU will be a hundred times less power consumption one percent. Yeah, I think so That is our company's major subject Most important subject because my website is called ARM devices, right? ARM CPU they try to use less power So it's very important for them to go even lower, right? Yeah, and Intel also looking at this, right? So that is one of the weakest subject for SEL You also work with the CPU R&B. Yeah display CPU or memory LSI memory Such a DRAM or flash memory That is because the flash memory of the device was invented by me so that which one Do you know the name of the flash memory flash memory? Yeah, that is the fundamental device Yeah, you invented. Yeah, you invent the flash memory When when was that? 1970 1970 so that 50 years ago And how did you invent this? How do you get the idea for flash memory? That is that I found the instability Then that the after that I think I want to apply to this instability in all his choices Then I invented the silicon floating gate with control gate That is often same structure of the flash memory Silicon floating gate and control gate control gate So that is the same structure absolutely absolutely the same structure of the present flash memory and Like it's just static memory. It's just stable. It stays that it does if you shake the device, it's okay Yeah, that is a non volatile Non volatile. Yeah so if Silicon chains to the exo this kind of the floating gate may change the new evil and the innovation But exo is that a type of silicon? And any limitation of silicon or a replacement replace replace silicon. Yeah replace it So it will not be silicon valley anymore will be exo valley. Maybe that ten years later Ten years later. Where will it be? The exo valley In the USA or somewhere else? Yeah, I don't know. You don't know. Yeah, but people are talking about 3d flash memory. I know how does that work? 3d the fundamentals and device structure is M O N O S But in the end mean the silicon nitride included the silicon cluster That also invented by me My invention is just a transistor no 3d structure Your inventions is is what part the transistor one element of the device So an element of device that that enables this then that that is Integrated to the 3d structure that people say the 3d non flash So that's gonna change a lot if it if they can make it more more 3d non flash It will be much more memory for lower price, right? I think so in the next two three years will happen I think so and also with exo. Well, what will do more memory lower price? What will it do? I think that the field application of the field are a little bit different the 3d non flash is the biggest capacitor or exact but 3d the Memory such as we say that those run or most run that is The first star and number of time that is about the performance about the battery consumption. What is about what? How will exo help the memory? It will help to get more memory or better memory or what? Yeah, that is The now that the air here the new application new market is requested one isn't that is very huge Taper scene of the memory that is not that is already known by tape or not 3d non flash but quick response and near CPU and No more time there is no solution at the present stage So that the exo LSI may be applied to that that is a big big subject So you had invention in the memory and the display in CPU you have something in the CPU that means the all of the application of the exos All the application could be used could be using exo But how does it feel for you to know that you invent something that so many people use? How's it feeling? You don't think about it, but anyway in the display field many people use TV or the ipad or like that that is very happy for me It makes you happy right as a researcher The invention will be used by the human being that is a so so important and so happy things to don't you? And and flash memory? Yeah, flash memory is now used everywhere everyone. Yes using personal computer or the like So you designed the memory for everybody. Yeah Everybody's memory is stored and the technology you invent. Yeah, it's special to think about that Don't you think that is a happy and very Fortunate things don't you think so? It's very fortunate. That means that means thanks to you You you giving memory to human people, right? Yeah, I think all the pictures After that the 8 will be grown That is so good for human being, don't you? How does it work when you have a challenge something new the needs a needed new solution? How do you work to invent something new? That is the new challenge as I said so that like a space shuttle How do you how do you get your your your company and your employees to think about finding a solution? How is the organization for this? That means there because that I'm the president so that by doing the research control by me and we are concentrating to To complete to the memory or CPU that we say GPU or GPGPU that will be used for Exile that is my fortune my last job biggest job and Everyday trying again to find a solution invent again and again Yeah, something new right that is the same as the conversation You know that and it must be a fun job, right to just sit down and try to yeah find a solution Because that so that The pattern so many things do more than 50% know the exo related pattern in the world So that we are the we are now making the way for the front from the other pioneer know the exos And here the conference is also the guys they invent the LCD the OLED Many and the plasma many guys around here. Is it nice to come to the SID display week? Yeah, talk with your friends, right your friends. Yes. We have so many friends Yeah, our position is a back plane not a front plane The back plane is more important Maybe for the active or very precise View then the active no back plane is very important How soon are you gonna have a flexible phone next year? Maybe Maybe next year or the year after the next and also maybe thanks to Exo. Yeah Exo must be the mass mass necessary
