Abstract
An electrode pattern of an electrostatic chuck includes linear portions in a radial direction and a plurality of concentric C-shaped portions branching out from the linear portions. The linear portions are disposed opposite to each other in a diametrical direction and are such that they lie on a line that is almost straight. The C-shaped portions are engaged alternately like teeth of a comb.
