Yes, I was referring to 70's and 80's. Even today, I think, there are applications where 150 nm process is perfectly fine - RFID, transportation cards etc.
If you look at the 74 TTL series dies, they look almost primitive. But perhaps these were one of the first attempts at ICs, so it is expected.
When did transition from hand-drawn to computer-generated designs happen?
