ELECTROSTATIC CHUCK AND ELECTRODE SHEET FOR ELECTROSTATIC CHUCK |
摘要 |
An electrostatic chuck having excellent chucking force and holding force is provided. The electrostatic chuck includes a laminate structure in which a first insulating layer, a first electrode layer, an interelectrode insulating layer, a second electrode layer and a second insulating layer are successively laminated on a metal base in an order of increasing distance from the metal base. The second electrode layer includes a pattern electrode having a plurality of opening portions within a flat area, and a shortest distance X between mutually opening portions and a length L of a line segment formed by feet of perpendiculars when barycenters of the adjacent opening portions are projected to a virtual line which is a straight line parallel to the shortest distance X satisfy L/X ‰§ 1.5 and L < 2.6 mm. |
