About United Microelectronics
Website ↗United Microelectronics Corporation operates as a semiconductor wafer foundry in Taiwan, China, Hong Kong, Japan, Korea, the United States, Europe, and internationally. It manufactures and sells integrated circuits. The company offers circuit design; mask tooling; wafer fabrication; and assembly and testing services for communication devices, consumer electronics, computer, and other applications. It also provides venture capital and marketing support; consulting and planning; energy technical; solar engineering integrated design; research and development services; and insurance services. United Microelectronics Corporation was incorporated in 1980 and is headquartered in Hsinchu City, Taiwan.
One company produces almost all leading-edge AI logic. N3/N2 capacity is allocated years ahead and every new fab is a multi-year, tens-of-billions bet.
What would prove us wrong. Weakens if leading-node utilisation falls while packaging and HBM stay loose — logic would no longer bind.
