Great news! Bring production to America and stop buying ChiCom.
Likely because it expects 5nm demand to continue quite some time into the future. While high-performance digital circuitry may benefit a lot from being made on the smallest process possible, analog and micro-power stuff prefers larger processes with tighter tolerances and lower leakage.Why would you plan to build a 5nm fab scheduled to open in 2023 now?
Different product classes require different fab processes. Why is Intel adding more 14nm fabs when 10nm and 7nm are incoming? Because 14nm will remain a workhorse for other stuff like EMIB and FOVEROS long after it falls out of favor for mainstream CPUs and GPUs.
Fab 11X is being upgraded from 32-45nm to 14-22nm, that is basically a whole new 14nm fab on its way for 2020-2021.Are they building new 14nm fabs? Or just increasing capacity at existing fabs, and using more 3rd-party 14nm fabs?
Pretty surprised if this is true. Isn't TSMC expected to hit 3nm in late 2022 to early 2023? Why would you plan to build a 5nm fab scheduled to open in 2023 now? Unless a 5nm fab is "easily" modified to produce 3nm wafers.
Yup, Intel's #18 is still doing 200mm 65nm wafers, last fab left that isn't on 22nm or better once 11X's upgrade is complete.Old fab lines pump out chips for years and years. Not every device needs cutting-edge. I think 200+nm fabs are still being used.
Probably not first risk production but to scale it. if it does some magic numbers as 7 brought, they will need every line they can muster to keep up with demand.Pretty surprised if this is true.
