Patent ID: 7223321

Claim:
An apparatus for plasma processing, comprising: a chamber defined by a bottom and surrounding walls; a substrate support disposed within the chamber; a thermally conductive adapter plate configured to interface with a top portion of the surrounding walls of the chamber, the adapter plate having a central opening defined to be positioned over the substrate support, wherein the adapter plate adapts a configuration of the surrounding walls of the chamber to a configuration of the central opening defined to be positioned over the substrate support; a window defined to cover the central opening of the adapter plate, an outer region of the window being configured to sit over the adapter plate to enable a seal about the central opening between the outer region of the window and the adapter plate; a metal shield disposed within the chamber over the substrate support, the metal shield being both proximate and parallel to the window, the metal shield being thermally connected to the adapter plate, wherein the adapter plate serves as a heat dissipation structure for the metal shield such that heat emanating from a plasma to be generated within the chamber is conducted through the metal shield to the adapter plate and away from the window.
