Abstract
A multichamber sputtering apparatus which is used for manufacturing a semiconductor device and the like. In the apparatus, a plurality of sputter chambers and a degas chamber are airtightly connected to and arranged around a center transfer chamber, and processes including sputtering are continuously conducted in a vacuum. A plurality of heat stages are disposed in the degas chamber so that a plurality of substrates are simultaneously heated. In each heat stage, as required, a heating gas introducing unit for introducing a heating gas with causing the heating gas to make contact with the rear face of the substrate, a pressing mechanism which presses the substrate against the heat stage so as to enhance the surface contact between the heat stage and the substrate, or an electrostatic chucking mechanism is disposed.
