ESC's field and application process

A key component that fixes the substrate to the lower electrode using the force of static electricity. When DC power is applied to the electrostatic chuck, opposite potentials are charged to the object, and forces attracting each other by the charged potential are generated

ESC is a component that fixes Wafer in semiconductor manufacturing equipment using electrostatic force, and is generally divided into Monopolar(Unipolar) and Bipolar types according to the number of electrodes, and is also divided into columb and Jonsen-Rahb types according to the size of dielectric layer resistivity
