Taiwan's semiconductor industry fab westward policy, 8-inch fab era is "total control, leading technology" as the two principles, which is to the 2005 cap to approve three 8-inch wafer fab is limit was foundry TSMC, and memory factory promos and Powerchip applications.Leading technology requirement refers to the mainland to set up 8-inch wafer semiconductor plant must have a 12-inch wafer fabs in Taiwan, and the 12-inch wafer production scale reached only after an application is made and can not be advanced processes. TSMC was Songjiang 8-inch plant and promos Chongqing Germany 8-inch plant successfully westward continent, PSC later is because of the DRAM industry boom decline, earnings losses year after year without the mainland.After the presidential election in 2009, began to discuss deregulation 12-inch wafer factories, although there is no semiconductor industry make the trip, but according to Taiwan's regulations, the case can be made in accordance with the mainland 12-inch wafer fab applications came UMC intends China Xiamen shares 12-inch fab, a joint venture with the local government.
