In brief

What this company does

United Microelectronics primarily engages in wafer fabrication for foundry customers. It also offers customers turnkey solutions by providing subcontracted assembly and test services. Its fabs are located in the R.O.C., Singapore, the PRC and Japan. Those fabs run 24 hours per day, seven days per week, with substantially all maintenance performed concurrently with production. Its primary customers by sales revenues include integrated device manufacturers such as Texas Instruments and Intel and fabless design companies such as MediaTek, Realtek and Novatek. The top ten customers accounted for approximately 57.0% of operating revenues in 2025. Sales are run from a main office in Taiwan for Asia, from the wholly-owned subsidiary United Microelectronics (Europe) BV in Amsterdam for Europe, and through UMC Group (USA) in Silicon Valley for North America, with further sales offices in China, Japan and Korea.
