Abstract: A process chamber for processing a substrate by conducting plasma enhanced chemical vapor deposition or sputtering includes a stage. The stage has a main base member that is constructed to have projections and a recessed portion between the projections, and a substrate mounting member which is constructred to fit between the projections of the main base member and such that the a portion of the substrate mounting member is located within the recessed portion and a portion of the substrate mounting member protrudes from the main base member. The substrate mounting member is easily removed from the main base member while also being reliably fixed and positioned in the main base member by the projections. As a result of this construction, the substrate mounting member can be removed from the process chamber independently of the main base member and in a manner similar to how the substrate is removed after processing.
