Claim Text:
1. A method of manufacturing a semiconductor device, using a film for forming a protective layer on a bumped wafer in which a low dielectric material layer is formed, the film for forming the protective layer comprising a support base, an adhesive layer, and a thermosetting resin layer, laminated in this order, wherein a melt viscosity of the thermosetting resin layer is 1×10 and a thickness of the thermosetting resin layer before being cured to form the protective layer is 0.05 times or more and 0.9 times or less a bump height of the bumped wafer, wherein the bump height is a distance from a first end of a bump of a plurality of bumps in the low dielectric material layer to a second end opposite the first end, and the bumps protrude from opposing ends of the thermosetting resin layer.
