Almost all of TSMC's top-10 customers have readied plans to adopt the foundry's 2nm GAA-FET (gate-all-around field-effect transistor) process technology, to be commercialized in 2025 and with a production ramp-up in 2026. This may make Samsung unlikely to fulfill its claimed goal of surpassing TSMC with its 2nm GAA technology within five years, according to industry sources.
