Elizabeth Sun, senior director at TSMC, said the company's 10nm process will account for less than one percent of TSMC's total revenue during Q1 2017.
EE Times also notes that TSMC is still undecided about whether it will implement extreme ultraviolet (EUV) for the first time on its fture 5nm or 3nm nodes:
While some industry executives say that Moore’s Law has reached its limit at 10nm, the top three chipmakers – Intel, Samsung and TSMC – are using three dimensional tweaks to take geometries to an “effective” 1nm. Earlier this month, TSMC said that it is planning to build a fab that will make 3nm SoCs as early as 2022.
Beyond 10nm, the roadmap to finer geometries is entering a new territory. TSMC has said it is still undecided on whether it will adopt extreme ultraviolet (EUV) lithography for 5nm and 3nm.
