The factory will be UMC’s second chip manufacturing plant in Japan, UMC’s first factory in Japan is Fujitsu Semiconductor’s Mie factory. The new 12-inch fab in Japan means a major shift in UMC’s strategy for building a fab. For decades, UMC has maintained most of its production in the area where its headquarters is located, and UMC’s move has allowed nearly half of its 12-inch wafers to be produced in Japan.
It is learned that UMC controls more than 20% of the global chip foundry service market, and its customers include Samsung, Qualcomm, and MediaTek. In addition, UMC also provides foundry services for important automotive chip manufacturers such as Denso, NXP Semiconductors, Renesas Electronics and Infineon.
