In a method for plasma ashing a resist film coated on a substrate, the temperature of the substrate is controlled initially at temperatures below that at which explosion of the resist film occurs until a surface portion of a resist film has been removed. Thereafter, the substrate temperature is increased to remove the remaining portions of the resist film. An apparatus for conducting the method includes a plurality of supports, which may be movably disposed within a vacuum treatment chamber for moving the substrate away from a source of heat and for moving the substrate into contact with the heating source.
