Abstract:
1. A thermally conductive sheet to be used between a mounting table for mounting thereon a target substrate and an annular focus ring mounted on the mounting table to surround a circumferential peripheral portion of the target substrate, the mounting table having therein a cooling unit and being disposed in a depressurized accommodating chamber for accommodating therein the target substrate, wherein the thermally conductive sheet has a non-adhesive layer on one or more surfaces thereof and the thermally conductive sheet is made of a gel type polymer; wherein said one or more surfaces include a mounting table side surface such that the non-adhesive layer is arranged between the thermally conductive sheet and the mounting table; wherein the non-adhesive film is a metal thin film; and wherein a thickness of the metal thin film is not less than 6 μm but not greater than 10 μm.
