In 2014, FSL and UMC agreed for UMC to acquire a 15.9% stake in MIFS from FSL through progressive phases. FSL is now cleared to transfer the remaining 84.1% of its shares in MIFS to UMC, with a final transaction value to acquire the remaining shares totaling ¥ JPN 54.4 billion. As a wholly-owned subsidiary of the Taiwan-based foundry, MIFS will be renamed as United Semiconductor Japan Co., Ltd. (USJC).

In addition to the equity investment in MIFS, FSL and UMC have had a mutually beneficial partnership through licensing of UMC's 40nm technology and establishment of a 40nm logic production line at MIFS. After several years of joint operations, both companies agreed on the benefits of integrating MIFS into UMC to strengthen UMC’s business foundation as a leading global semiconductor foundry with a broad customer portfolio, enhanced manufacturing expertise and extensive technology offerings, enabling MIFS to maximize its potential, enhance Japan’s semiconductor industry competiveness and drive values to UMC’s stakeholders.

Jason Wang, co-president of UMC, said, “This win-win acquisition will create synergies through the integration of USJC’s world-class production quality standards and employees with UMC's decades of manufacturing experience, economy of scale and foundry expertise to provide enhanced support for new and existing Japanese customers. Meanwhile, UMC’s global customers will gain access to a volume production 300mm fab in Japan.”

Co-president Wang continued, “The addition of USJC also complements UMC’s strategy of developing a diversified 300mm manufacturing capability across Asia. Going forward, we will continue to stay focused on our strength in Specialty Technologies and explore growth opportunities in line with this strategy through the evaluation of both internal and external capacity expansion opportunities.”
