Since the set-up and operating cost for a 12-inch IC fab is tremendously expensive, a more profound understanding of the utility costs involved in operating a 12-inch IC fab is understandably helpful to the top management of an IC manufacturing company, allowing them to make more informed decisions on whether they construct new fabs or out-source their products to foundry fabs. The purpose of this study aims to summarize the unit utility consumption for an 8-inch IC foundry fab with full-scale operating costs for water, electricity and bulk gas utilization, based on the latest practical production fabs, and forecasts the utility consumption per unit for a fully functional 12-inch foundry fab. In addition, the study demonstrates the IC foundry fab utility running cost comparison among different sites, including Hsinchu, Singapore and Shanghai. With this comparison model, an IC manufacturing company will be able to efficiently forecast the utility running costs in an 8 or 12-inch IC foundry fab.
