UMC is a Taiwanese contract chipmaker (foundry) that manufactures chips designed by other companies, mostly on mature, older-generation process technologies used in phones, displays, cars, networking and industrial electronics.
UMC does not make leading-edge AI processors, but it supplies the mature-node chips that surround them and is building AI-related capacity in silicon photonics and advanced packaging; its chairman said in July 2026 that generative AI is accelerating demand for greater system integration.
Chip design companies and device makers pay UMC to manufacture wafers of their chips.
