Abstract:
A protective tape including an adhesive agent layer, a thermoplastic resin layer, and a matrix film layer in this order to a surface of a wafer on which a bump electrode is formed; grinding a surface of the wafer opposite to the surface on which the protective tape is pasted; pasting an adhesive tape to the ground surface of the wafer; peeling the protective tape so that the adhesive agent layer remains and other layers are removed; dicing the wafer to which the adhesive tape is pasted to obtain individual semiconductor chips; and curing the adhesive agent layer before dicing; the adhesive agent layer after curing has a shear storage modulus of 3.0E+08 Pa to 5.0E+09 Pa, and the ratio of the thickness of the adhesive agent layer of the protective tape before pasting to the height of the bump electrode is 1/30 to ⅙.

Claim (Index 10):
A method for manufacturing a semiconductor device, comprising steps of:\n pasting a protective tape to a surface of a wafer on which a bump electrode is formed, the protective tape having an adhesive agent layer, a thermoplastic resin layer, and a matrix film layer in this order; grinding a surface of the wafer opposite to the surface on which the protective tape is pasted; pasting an adhesive tape to the ground surface of the wafer; peeling the protective tape so that the adhesive agent layer remains and other layers are removed; dicing the wafer to which the adhesive tape is pasted to obtain individual semiconductor chips; and curing the adhesive agent layer before dicing, wherein the adhesive agent layer after curing has a shear storage modulus of 3.0E+08 Pa to 5.0E+09 Pa, and wherein the ratio of the thickness of the adhesive agent layer of the protective tape before pasting to the height of the bump electrode (the thickness of the adhesive agent layer before pasting/the height of the bump electrode) is 1/30 to \u2159.
