January 10, 2024 /SemiMedia/ -- United Microelectronics Corporation (UMC) announced that the construction of its new 22nm wafer fab in Singapore will be completed in mid-2024, with mass production expected in early 2025.

UMC's new fab in Singapore is based on the expansion of its Fab12i fab. The monthly production capacity of the first phase of the new fab is planned to be 30,000 wafers, and mass production is expected to begin at the end of 2024. The new fab will provide 22/28nm process, with a total investment of US$5 billion.

UMC has operated a 12-inch wafer fab in Singapore for more than 20 years, and the Fab12i fab is UMC's advanced special process R&D center.

UMC said that the construction will enter the peak of expenditure, and other fabs will also have routine capacity expansion. Capital expenditures in 2024 are determined to be higher than last year's US$3 billion.
