TSMC is developing its 1.4nm process tech, called A14, with mass production expected for 2025. The company is exploring vertically-stacked complementary field effect transistors (CFETs) but is unlikely to adopt them in the near future. The A14 process may rely on TSMC's 2nd or 3rd generation gate-all-around FETs (GAAFETs), and the adoption of High-NA EUV lithography tools is a possibility.
