Patent ID: 8082977

Claim:
A mounting apparatus comprising: a surface plate; a temperature control unit integrated with the surface plate; and a bottom plate integrated with the temperature control unit via a heat insulation ring, wherein a temperature of a target object held on the surface plate is controllable, wherein the surface plate is formed of ceramic, wherein a central portion of the surface plate is coupled to the temperature control unit via first coupling members such that a peripheral portion of the surface plate is not coupled to a peripheral portion of the temperature control unit, wherein the peripheral portion of the temperature control unit is coupled to the heat insulation ring by second coupling members, wherein the first coupling members include first female screw portions disposed in the central portion of the surface plate and first male screws, wherein the temperature control unit includes first through holes, wherein the surface plate and the temperature control unit are fixed together via the first male screws inserted into the first female screw portions via the first through holes, wherein the second coupling members include second female screw portions disposed in the peripheral portion of the temperature control unit and second male screws, wherein the heat insulation ring includes depressions having second through holes, wherein the temperature control unit and the heat insulation ring are fixed together by the second male screws inserted into the second female screw portions via the second through holes, and wherein the second male screws are received in the depressions.
