摘要： Proposed is a ceramic-made electrostatic chuck consisting of two insulating ceramic layers and a metallic electrode layer integrally sandwiched between the two insulating layers, which has a very quick response characteristic to turning-on and -off of the electric voltage applied to the electrodes without affecting the very high electrostatic attracting force.
