Powerchip Technology Corporation (PTC) was founded in HsinChu Science Park in December 1994. An 8-inch fab was completed in 1996, and DRAM production commenced.

PTC has successfully transformed from a DRAM manufacturer into a foundry service provider. To further affirm its market positioning, in May 2019 PTC transferred related assets and business of its three 12-inch fabs in Taiwan to Powerchip Semiconductor Manufacturing Corp. Subsequent foundry business activities in Taiwan, including wafer fabrication and sales, shall be executed by Powerchip Semiconductor Manufacturing Corp. After restructuring was completed, Powerchip Technology Corp. became a high-tech holding company. PTC invests in Powerchip Semiconductor Manufacturing Corp., Taiwan and Nexchip Semiconductor Corp., China.

In 2002, the first 12-inch fab began production. Eventually PTC expanded to three 12-inch fabs with a total monthly capacity of 100,000 wafers. In 2015, PTC signed an agreement with HeFei City in China esta
