History
  • On May 22, 1980, UMC was spun off from the Industrial Technology Research Institute and was formally established as the first private integrated circuit company in Taiwan, Republic of China.
  • 1985: UMC was officially listed on the Taiwan Stock Exchange (code: 2303). It was the first listed semiconductor company in Taiwan. At that time, Morris Chang ever was its chairman.
  • 1995: UMC decided to transform from an IDM company with its own products to a professional pure-play foundry.
  • 1996: Spun off its IC design units to establish MediaTek, Novatek, ITE Technology, Faraday Technology, AMIC Technology, and Davicom.
  • 1999: Fab 12A 12-inch wafer fab in Tainan Science Park was officially established.
  • 2000:
    • Lists on the New York Stock Exchange (code: UMC) as Taiwan's first semiconductor company to do so.[3]
    • Produces the first chips using copper process technology and the first 0.13 micron ICs in the semiconductor industry.
  • 2004: 12-inch wafer fab in Singapore enters mass production.
  • 2008: Listed as a constituent stock on the Dow Jones Sustainability Index (DJSI) for the first time.[4]
  • 2010: 30th anniversary of the company.
  • 2013: Fully acquires "Hejian Technology Wafer Fab" in Suzhou, Mainland China.
  • 2015: USCXM 12-inch wafer fab located in Xiamen, Fujian Province, China was officially established. [5]
  • 2017: 28nm mass production begins at USCXM in Xiamen, Mainland China.
  • 2019: Fully acquired Japan-based Mie Fujitsu Semiconductor. [6][7][8]
  • 2020: Reached a plea agreement with the U.S. Department of Justice to resolve a 2018 trade secrets case.[9]
