Aizu Fujitsu Semiconductor Wafer Solution Limited

For the 150mm (6 inch) wafer fab, we provide optimum wafer foundry services for analog products and microcontrollers used for digital home electronics, automobiles and industrial equipment. This fab has a capacity of ~14.000 wafers/month produced on ~10,000m2 floor space. We also started mass production of Gallium nitride (GaN) power devices in the second half of FY2014 ahead of other manufactures. This device is expected to greatly reduce power loss during power conversion and to contribute to the achievement of a low-carbon society.
