Abstract
A focus ring to be detachably attached to a top surface of an outer peripheral portion of a mounting table in a processing chamber, includes: an annular main body having a back surface to be attached to the top surface of the outer peripheral portion of the mounting table. And a thermally conductive sheet fixed to the annular main body, the thermally conductive sheet being interposed between the annular main body and the top surface of the outer peripheral portion of the mounting. The thermally conductive sheet is fixed as one unit to the annular main body by coating an unvulcanized rubber on one surface of the thermally conductive sheet, bringing said one surface into contact with the annular main body, and heating the thermally conductive sheet and the annular main body to vulcanize and to adhere the thermally conductive sheet to the annular main body.
