Abstract:
There is provided a semiconductor device manufacturing method including: forming a first mask film composed of a polymer having a urea bond by supplying a raw material to a surface of the substrate for polymerization; forming a second mask inorganic film to be laminated on the first mask film; forming a pattern on the first mask film and the second mask inorganic film and performing an ion implantation on the surface of the substrate; removing the second mask inorganic film after the ion implantation; and removing the first mask film by heating the substrate after the ion implantation and depolymerizing the polymer.

Claim (Index 10):
A vacuum processing apparatus, comprising:\n an ion implantation module configured to implant, in a vacuum atmosphere, ions into a substrate in which a first mask film composed of a polymer having a urea bond and a second mask inorganic film laminated on the first mask film are formed and in which a mask pattern is formed on each of the first mask film and the second mask inorganic film; an etching processing module configured to supply an etching gas to the substrate to remove the second mask inorganic film in the vacuum atmosphere after the ion implantation; and a removal module configured to remove the first mask film by heating the substrate in the vacuum atmosphere, after the ion implantation, and depolymerizing the polymer.
