Vanguard International Semiconductor Corporation (VIS) is a specialized IC foundry service provider. It is founded in December 1994 in Hsinchu Science Park, Taiwan, by Morris Chang. In March 1998, VIS became a listed company on the Taiwan Over-The-Counter Stock Exchange (OTC) with the main shareholder being TSMC, National Development Fund and other institutional investors.
VIS was working as a subcontractor for TSMC for the manufacturing of logic and mixed signal products, primary focusing on the production and development of DRAM and other memory IC. In 2000, VIS announced its plan to transform from a DRAM manufacturer into a foundry service provider. As of February 2004, VIS completely terminated its DRAM production and became a pure-play foundry company. In 2007, VIS has acquired the 8-inch fab of Winbond Electronics Corp. expanding its production ability.
VIS currently has two 8-inch fabs with a monthly output of approximately 110,000 wafers.
