"Now, if only you could process individual chips of Silicon in the way that you could thick film or thin film hybrids."
I tried to buy Trilogy's Fab, back in late 1984/early '85, when they were attempting to not go under ... Unfortunately, all I have in my collection is a few trays of 4-inch "system on a 2.5 inch chip" wafers in various layer steppings, a couple of masks, and a couple of lab-grown un-cut silicon ingots. If I had managed to purchase the Fab, I'd probably still be able to do what you suggest.
Maybe. Going down hill with a stiff tail wind ;-)
I can cut and polish silicon ingots into wafers, I have a HyPOx, and a Class 10 clean-room, but ... Lots of this old stuff is pretty much impossible to get "day-to-day" functional these days, for a lot of reasons. And probably a waste of electricity to even try. I only keep the kit around because I have the space, and hope that eventually there will be a place in a museum for it.
The old screen printer keeps on chugging, though ... and the laser can still cut the resistors, according to what the CAD system recommends for any given hybrid. I fire it up several times per year, and always at a profit.
