TSMC stock
On September 25, 2026, industry reports indicated that TSMC commenced pilot production runs for its next--generation 1.4nm (A14) process node at Baoshan Fab 20 in Hsinchu and Fab 25 in the Central Taiwan Science Park. The A14 node integrates second--generation gate--all--around (GAA) nanosheet transistors and the NanoFlex Pro standard cell architecture, delivering a projected 10% to 15% speed increase or a 25% to 30% reduction in power consumption relative to the 2nm (N2) node. Yield progression is tracking ahead of internal expectations, keeping TSMC positioned to commence risk production in 2027 and commercial high--volume manufacturing in 2028, reinforcing its competitive positioning against Intel's 14A node.
