Abstract:
The present invention relates to a first protective film-forming sheet formed by stacking a first pressure-sensitive adhesive layer on a first base material and stacking a curable resin layer on the first pressure-sensitive adhesive layer, in which the curable resin layer is a layer to form a first protective film on a bump-provided surface of a semiconductor wafer by being attached to the surface and cured, a sum of a thickness of the curable resin layer and a thickness of a first pressure-sensitive adhesive layer is 110 μm or more, and the thickness of the curable resin layer is 20 μm to 100 μm.

Claim (Index 4):
A method for forming a first protective film that protects a circuit surface and bumps of a semiconductor wafer having the bumps formed on the circuit surface, the method comprising:\n a step of attaching a curable resin layer of a first protective film-forming sheet formed by stacking a first pressure-sensitive adhesive layer on a first base material and stacking the curable resin layer on the first pressure-sensitive adhesive layer to the bump-provided surface of the semiconductor wafer; a step of heating the curable resin layer; a step of laminating the circuit surface and the bumps of the semiconductor wafer; a step of forming the first protective film by curing the curable resin layer; and a step of peeling the first base material and the first pressure-sensitive adhesive layer, wherein a sum of a thickness of the curable resin layer and a thickness of the first pressure-sensitive adhesive layer is 55% or more of a height of the bumps, and the thickness of the curable resin layer is 10% to 50% of the height of the bumps.
