When handling silicon wafers for semiconductor devices or glass substrates for liquid crystal panels, it is necessary to adsorb and fix these items within the vacuum chamber of the equipment. The device that generates and controls this adhesive force (the amount of charge appearing on the plate surface) is called a "high voltage power supply (ESC: Electric Static Chuck)." Advantages of P.R.A. ESC Power Supply Most high voltage power supplies for ESC used in semiconductor manufacturing equipment are produced overseas, leading to issues related to technical applications and after-support. At P.R.A., we address these issues by designing and developing custom specifications from the design and circuit board stage, resulting in an ESC power supply that achieves improvements, low cost, short delivery times, and long lifespan.
