ESC Power Supplies for Semiconductor Process

PSTEK’s electrostatic chuck power system for semiconductor processing can improve the productivity of processing by achieving an effective dechucking, using the function of load electric discharge based on internal ground. Various protection functions such as built-in RF filter and digital arc regulation not only can effectively protect devices and wafers but also can minimize the defect rate.

This product stability and productivity has been proven through extensive field testing at large Korean companies.
