 Hi, I'm here at the IoT TechEx show in Berlin. I'm at the booth of IMEK. I've known IMEK for at least 15 years. I've got to say I think they're a phenomenal organization. They work on some really innovative technologies and they're going to tell us a bit more about it. Let's start off with you Prashant. Nice to meet you Prashant. Thanks for coming. Good morning. What are you doing? So here we are actually presenting our work on organic TFT. So these are TFT technology that we have developed in collaboration with Fujifilm. So Mr. Gotosan is from Fujifilm and they have actually developed a new semiconductor material and at IMEK we have developed the whole process stack using those semiconductor material and we have developed the organic TFT and here we are kind of demonstrating a seven segment display where all the circuits are actually in organic TFT developed with the Fujifilm material. What have been the benefits of this material versus other previous generations from others? So this is a new organic semiconductor material. It's really air stable and also the temperature budget, thermal budget for the processing is really high and also it's stable after hot lithography technology. So I know there are many demonstrators which are produced by printing or such kind of things but we take hot lithography because it's more compatible with current industry systems. So the size of the transistors, the length of the transistors is just five micro. It's ten times smaller than the other printed TFTs so we can get much better performance in terms of TFTs. So this is a collaboration between IMEK and the other innovation that we have done here is on the topology of the TFT itself. So this is an organic TFT where the contacts are at the top and we have also now it's a work in progress where we have replaced gold contacts with copper contacts. So and the purpose of doing that is to make production of these TFTs compatible with flat panel display facts because they like top contact and they don't like gold. So most of the legacy organic TFTs, they are bottom contact and they use gold in their transistors. How reliable is copper being? The way copper oxidizes has been the issue for us. That is true. So those are the challenges today we are working on them. So indeed there are stability issues with copper but given that it is cheaper than gold and it is more compatible with fabs. So we are currently working on it. We have explored other materials also but it's a work in progress to make copper more stable. And Goethe-san you talked about stability of materials and what level of protection they need. They need a very high barrier property for example and what sort of lifetime testing have you done if you've done that so far? Well actually we store our samples without any protections. Just leave it like half a year on my desk. I'm ready to store to put it back to Globox or somewhere. But still the mobility doesn't change at all. So at least for the material wise it's quite stable. Now of course in case of OTFTs we need to think about the size of the transistors when we talk about mobility. So we achieved mobility more than one with the five micro channel lengths. So I know there are some reports which show the mobility 10 or something but the channel lengths is 100 or 200 but we got such a mobility with very small channel lengths. We believe this is one of the top value in this field. Have you created all the materials so the organic semiconductor is dielectric and the others or is it mainly the organic semiconductor that you're focused on? So our main goal is to make the process very compatible with the current industry system. So if we just replace one material like from amorphous silicon to OTFT it's not so difficult. But if we want we need to replace all of them it's not so preferable for the industry. So in our case every other material in the process is basically compatible with the current industry. What about scaling this up? It's one thing producing one another thing producing many in volume. What's the work you've done on that? So what we have so far done is that we started with very small substrates. The first demonstrator was actually on a three by three centimeter. Now within IMAG we have scaled it to six inch substrates. So and we have got good performance on six inch substrates. So that is the scaling we have done so far and the step after that is still a work to be done. Very cool. Dr. Agarwal and Goethe San, thank you very much. Thank you very much. Can you go inside? So this is a very high resolution OLED display. You can post the mic here. So this is a European project called high response. And the objective of this project was to manufacture a very high resolution OLED display. So this is done in collaboration with Toronto for PNO and IMAG so there are three parties. And this project actually got an award which will be presented this evening. Is it a full HD? No it's not a full HD. It's about 160 by 160 today. And the size? And it's a printed OLED that has been used. What's the size? So this is 160 by 160 pixels and I think the pixel size is 10 microns. This is like less than one inch or diagonal right? Much smaller than that, yes. So actually I can remove this box for you to see it well. So currently we have a sort of a video that is looping on it with logos of IMAG, front offer and bolt centre and TNO. So printing displays is one of the areas of focus that you are looking at? So the printing expertise comes from front offer. We developed the back plane and then demonstrated. What is the back plane technology? So it's an upset place. Thank you very much. Thank you very much.
