Leading Foundry Solutions

UMC is committed to Specialty Technologies that serve upcoming growth markets, particularly 5G, IoT and Auto ICs. We lead in many areas such as 80eHV TDDI & 40eHV/28eHV TDDI technology and shipments, and our specialty market share continues to grow, especially on 12-inch manufacturing.


Furthermore, as IP has become a critical resource for today’s SoCs, we have worked to provide fundamental as well as more specialized IP that are optimized for portability and cost, developed both internally and from third-party partners.


Our multiple fabs across Asia featuring world-class defect densities and cycle times ensure ample capacity and manufacturing quality. Come explore how UMC’s specialty processes can help power your next generation IC design.

Diversified Manufacturing

UMC is a foundry manufacturing leader with several advanced 12-inch fabs in operation. Fab 12A in Tainan, Taiwan has been in volume production for customer products since 2002 and is currently manufacturing 14 and 28nm products. The multi-phase complex is actually three separate fabs, consisting of Phases 1&2, 3&4, and 5&6. Fab 12A’s total production capacity is currently over 87,000 wafers per month. UMC’s second 12-inch fab, Fab 12i, is located in Singapore’s Pasir Ris Wafer Park. This second-generation 12-inch facility is also in volume production, with capacity at 50,000 wafers per month. UMC’s 3rd 12-inch fab, United Semi in Xiamen, China, began volume production in Q4 2016. The total design capacity of United Semi is 50,000 wafers per month when fully equipped. UMC also acquired USJC in Japan in October of 2019. This 12-inch fab, based in Mie Prefecture, provides 33,000 wafers per month capacity for logic and specialty processes down to 40nm.


Combined with our seven 8-inch fabs and one 6-inch specialty fab, UMC provides stable and diversified manufacturing with leading production efficiency.
