Vanguard International Semiconductor Corporation (VIS) is a Taiwanese specialized IC foundry service provider, founded in December 1994 in Hsinchu Science Park by Morris Chang.

History
VIS was working as a subcontractor for TSMC for the manufacturing of logic and mixed signal products, primarily 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.
VIS acquired Fab 4 and Fab 5, two lines of 200-mm fab from Winbond Electronics Corp., expanding its production ability. The purchase was finalized in January, 2008.[1]
As of 2018, VIS has a production capacity of approximately 199,000 wafers per month.[2]
