Development of comprehensive WIP performance monitoring system for semiconductor fabrication foundry: a qualitative action research approach

The Complementary Metal Oxide Semiconductor (CMOS) is a complex and delicate process in the semiconductor industry. In typical 30,000 wafer capacity of a single foundry business model, the CMOS products are mixed of various technologies to serve wider market segments. Total devices range from 100 to...
