If that rabbit hole appeals, the ITRS reports (now called IRDS[2]) are very good mid-level, year-by-year summary of the state of the art in chipmaking, including upcoming challenges and future directions. > Being able to print something in nanometers is an overlooked technical achievement for human manufacturing. IMO, a semiconductor fab probably is the highest human achievement in terms of process engineering. Not only do you "print" nanometric devices, you do it continuously, in a multi-month pipelined system and sell the results for as little as under a penny (micros, and even the biggest baddest CPUs are "only" a thousand pounds, far less than any other item with literally a billion functional designed features on it).
