Production volume of 12 inch and above foundry wafer in Taiwan 2013-2022
In 2022, the production volume of silicon wafers sized 12 inches and above amounted to about 15 million pieces in Taiwan. A wafer is a sheet of semiconductor material that is the basis for integrated circuits and photovoltaics. The size of the wafer refers to their diameter, and the higher the diameter, the higher the technological sophistication of the product because a larger wafer means improved throughput and lower production costs. The 12 inch or 300 mm is currently the largest wafer available in the industry.
