Substrate holder having electrostatic chuck and method of fabricating the same

摘要

Provided is a substrate holder including a susceptor having edge protrusion formed on edge thereof and an electrostatic chuck mounted inside the edge protrusion and on the susceptor. The electrostatic chuck is attached to the susceptor by a gel adhesive sheet containing a plurality of wires and a silicon or corrosion-resistant epoxy based material is filled between the electrostatic chuck and the edge protrusion. The planarity of the electrostatic chuck can be maintained accurately when the electrostatic chuck is attached to the susceptor and clogging of cooling gas supply holes and leakage of cooling gas through a space between the electrostatic chuck and the susceptor can be prevented.
