Abstract:
A vacuum processing apparatus comprising a vacuum chamber and a mounting stand provided within said vacuum chamber for a substrate to be processed, said mounting stand comprising a cooling portion having a cooling means and a dielectric plate provided on top of said mounting stand for supporting said substrate, said supporting dielectric plate including a heater and an electrode that configures an electrostatic chuck for electrostatically attracting said substrate, said vacuum processing apparatus further comprising:an intermediate dielectric plate linked to a surface of said cooling portion with an annular synthetic resin sealing member therebetween and having an electrode configuring an electrostatic chuck embedded in a surface thereof; a system for supplying a fluid for thermal transfer into a region surrounded by said sealing member between said cooling portion and said intermediate dielectric plate; and said supporting dielectric plate being linked to the surface of said intermediate dielectric plate by the electrostatic force of said electrostatic chuck of the intermediate dielectric plate.
