 So we're now we're now designing in CMOS process at 3 nanometer. How did we get from here from 1969 to 70 to now to this type of 3 nanometer CMOS process technology? Because MOS are surface devices. You can you can squeeze you can you can reduce the size of bipolar. Bipolar are three dimensional devices. They are bulk devices so you can you can reduce the size. So the this reduction gradual reduction of size was what allowed to go faster denser lower cost combined with larger wafer sizes. So so we you know we are talking about a process that essentially for 50 years has been you know has been driving this industry. Unfortunately we are close to the end of this line. So you know three nanometers I don't I you know the next the next step is you know square root of 3 so 1.7 nanometers. I don't know that anybody knows how to do that and the cost the 250 million dollar for a lithography machine. When you first created the process how much did those machines 25,000 $25,000 big scale a way for a liner was 25,000 dollars. I mean the you know the contact less were more like 40,000 but you know that's just unbelievable. I mean you could you know anybody could make his own fab now how can you you know you have to shut out 10 billion dollars for fab right. So what do you do. So you talked about planes one of the key pillars of ST was Bruno Morari and he also was very interested in in planes. Do you have any like personal stories or interactions with the people like Pasquale Pistorio or Bruno? Of course yeah yeah actually with Bruno you know Bruno we went to Germany together to present some ideas on neural networks because you know at the time when I was CEO of synaptics because you know he was interested in neural networks as well and so you know and I you know we were there was nothing that I consider proprietary in those days we were just playing with you know stuff. So you know and I got to knowing much more I only had met him before when I was working in 67 because it was an application in those days but then he became a force you know an innovator within within SSGS and ST and I bought a high respect for him and and Pasquale actually at one point I interview him to take over to become CEO of synaptics but his wife wanted to go back to Italy so there you go. That would have been an interesting evolution of both companies. Actually he would have done better than I because he was senior and he understood much more about you know I mean he had worked for Motorola so he had a broader view it would have been the the right thing to do but.
