The Industry Leader

Founded in 1980 as Taiwan's first semiconductor company, UMC led the development of the commercial semiconductor industry in Taiwan. It was the first local company to offer foundry services, as well as the first semiconductor company to list on the Taiwan Stock Exchange (1985). UMC is responsible for many local industry innovations, including the introduction of the employee share bonus system, often credited as a primary factor in the development of a prominent electronics industry in Taiwan. UMC also enables customers to access complete supply chain information online through the MyUMC online service portal, an industry first when it was introduced in 1998.

Leading Foundry Solutions

UMC is committed to the timely delivery of leading-edge solutions that serve the specific and unique requirements of our customers in the face of today's advanced applications. UMC collaborates closely with customers as well as partners throughout the entire supply chain, including equipment, EDA tool, and IP vendors to work synergistically towards each customer's SoC silicon success. We also possess the required knowledge in system design and architecture necessary to properly integrate customer designs with advanced process technologies and IP. The result is a greater chance of first pass silicon success for today's SoC designs.

UMC's comprehensive foundry solutions start from a common logic-based platform, where designers can choose the process technology and transistor options that best fit their application. From there, technologies such as RFCMOS and embedded Flash can be used to further fine-tune the process for customers' individual needs. Furthermore, as IP has become a critical resource for today's SoCs, we have worked to provide basic design building blocks as well as more complex IP that are optimized for portability and cost, developed both internally and from third-party partners.

With advanced technology, a broad IP portfolio, system knowledge, and advanced 300mm manufacturing, UMC offers comprehensive solutions that help customers deliver successful results in a timely fashion.

World-Class Manufacturing

UMC is a 300mm manufacturing leader with several advanced 300mm fabs in operation. Fab 12A in Tainan, Taiwan has been in volume production for customer products since 2002 and is currently manufacturing products down to 14nm. 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 75,000 wafers month. UMC's second 300mm fab, Fab 12i, is located in Singapore's Pasir Ris Wafer Park. This second-generation 300mm facility is also in volume production, with capacity at 50,000 wafers per month. 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 300mm fab, based in Mie Prefecture, provides 33,000 wafers per month capacity for logic and specialty processes down to 40nm. Combined with our seven 200mm fabs and one 150mm specialty fab, UMC has a total monthly capacity of over 750,000 8" equivalent wafers.
