Foundry TSMC does not need to use high-NA extreme ultraviolet lithography tools for the manufacture of chips on its A14 (1.4nm) process according to reports from the TSMC North America Technology Symposium.

The company introduced the A14 process at the symposium saying it is expected to enter production in 2028. It has previously been stated that an A16 process due to appear late 2026 and that too does not require a high-NA EUVL tool.
