And so instead of using an imager to collect the image, you use a projector to project the image back down through the optics system. where now you project some shape you want to manifest on a chip. But you can't see it. You could look at it with your eyes, but you couldn't see it. But you're using this projection system through the microscope in reverse to put the image down on the chip.

So now the next thing you do is you take, let's say you've got a silicon wafer. And then you go through and you apply something we call photoresist. It's like a really thick, almost like a honey type of consistent, a little thinner than that. But you put some photoresist on the wafer and then you spin it at really high RPM and it spins that photoresist so that it's very thin.

And you take that wafer with the photoresist and you expose it to the image you want to put onto it with ultraviolet light. And so that hardens part of that photoresist. And then you develop that wafer to remove all of the photoresist that was not exposed to the ultraviolet light. And then maybe you expose it to a plasma and you etch it.

And so every place where there's no photoresist, it etches the surface. But where the photoresist survived because you exposed it with your ultraviolet light,

light you now have an image so you could look at that with a microscope again and then you'd see you know jamie's mug on the surface of the silicon wafer and so in concept that's how the idea of when you make a cpu or you make memory or you make any of this digital technology that's that's technically how it works you are you old enough to remember uh microfiche what is that

Yeah, the little acetate things in school that you put in. Yeah, yeah, yeah. So that's another kind of illustration of it, but just not applied to a chip, right?

Or in some cases, they took functionality out because they couldn't get the ding-dang chips to go do what they wanted to go do. Yeah, I was really glad to see a lot of attention be brought to bear with, I think it was the CHIPS Act issue. And even Texas has taken a very strong stance on trying to attract some chip manufacturing capability here in Texas, right?
