United Microelectronics Corporation (UMC; Chinese: 聯華電子; pinyin: Liánhuá Diànzǐ) is a Taiwanese company which is based in Hsinchu, Taiwan. It was founded as Taiwan's first semiconductor company in 1980 as a spin-off of the government-sponsored Industrial Technology Research Institute (ITRI).
UMC is best known for its semiconductor foundry business, manufacturing integrated circuits wafers for fabless semiconductor companies. In this role, UMC is ranked behind competitors TSMC and GlobalFoundries. It has three 300 mm fabs, one in Taiwan, one in Singapore, and one in China.
In the 1980s, UMC produced a popular clone of the Motorola 6845 CRT controller named the UM6845E.
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. 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.
