Semiconductor foundries across the board are preparing to raise price quotes of their 8-inch wafers from 2021. A DigiTimes report sheds light on various foundry companies, including UMC (United Microelectronics), Global Foundries, and Vanguard International Semiconductor (VIS) have raised their 8-inch foundry quotes by 10-15% in Q4-2020, with the quotes set to rise by another 20-40% in 2021. Foundries don't tend to use flat pricing, and instead rely on quotes specific to the size and design requirements of an order (by a fabless chip designer).
The foundry industry operates broadly on silicon fabrication nodes and wafer sizes. This article by Telescope Magazine provides insights into the typical use-cases for each wafer size. Although pertaining strictly to pricing of 8-inch (200 mm) wafers, an impending price-rise across the semiconductor industry can be extrapolated on the basis on significant labor cost increases. TSMC is planning to implement a 20% pay hike for its personnel in 2021.
