TSMC broke ground for construction of Fab 14 Phase 6, located in Southern Taiwan Science Park (STSP). The new facility will boost the foundry's 12-inch wafer production capacity, leading the way to construction of Phase 7 in 2013. TSMC's facilities in STSP generate 42% of the company's revenues, with a production value of US $6 billion, hiring over 9,000 employees. Phases 1~4 of Fab 14, which specializes in 12-inch wafers, has a quarterly foundry capacity of 540,000 12-inch wafers to produce over 1,200 different types of ICs for about 150 clients a year, according to company executive vice president and co-COO Chiang Shang-yi. In 2013-14, TSMC Fab 14 will become the world's first fab with 20 nanometer SoC volume production, and the company's first plant to start 16 nanometer FinFET volume production.
