HistoryEdit

In 1990s, UMC briefly marketed the U5 series microprocessors, an enhanced version of Intel 486, as well as chipset controllers for Socket 3 and Socket 5 microprocessors.

UMC was the first foundry to produce chips on 300 mm wafers, ship wafers using copper materials, to sell 65 nm ICs to customers, and to produce chips using 28 nm process technology.[1] It was the first Taiwanese company to offer foundry services and the first semiconductor company to be listed on the Taiwan Stock Exchange in 1985. In 2000, UMC's Fab 12A became the first 300mm fab to enter production in Taiwan. In 2004, UMC's Fab 12i became the first 300mm fab in Singapore to enter production.

The United States Department of Justice indicted UMC over charges of economic espionage on September 27, 2018 and unsealed on November 1, 2018.[3]
