The Near Impossibility of Making a Microchip

(1/1)

Alex Eisenhut:
Found this cool little PDF while reading about IC fabrication, specifically about the Micralign from the 1970s. It's more of a history lesson.

Thanks for sharing. I love those stories from early electronics and computing.  :-+

Thanks for the link.

Today these SOTA systems are producing 5nm chip features on 12 inch wafers, and cost ~$300M!!

Remember ~15 years ago when we had a 40nm CMOS that cost ~$4M just for the masks alone!!  Have no idea what a 5nm mast set cost today!

Best,
