As several chipmakers ramp up their 10nm finFET processes, with 7nm just around the corner, R&D has begun for 5nm and beyond. In fact, some are already moving full speed ahead in the arena.
TSMC recently announced plans to build a new fab in Taiwan at a cost of $15.7 billion. The proposed fab is targeted to manufacture TSMC’s 5nm and 3nm processes, which are due out in 2020 and 2022, respectively. Other chipmakers, including GlobalFoundries, Intel and Samsung, also are looking at technologies for 5nm and beyond.
