  • Method for manufacturing semiconductor device and surface protective tape
    Patent number: 8444799
    Abstract: A method for manufacturing a semiconductor device includes adhering an adhesive layer of a surface protective tape including a base material film, an intermediate layer disposed on the base material film, and the adhesive layer disposed on the intermediate layer to one surface of a semiconductor substrate; curing the intermediate layer while a flat plate is pressed against the base material film of the surface protective tape; grinding the other surface of the semiconductor substrate; curing the adhesive layer; and separating the surface protective tape from the semiconductor substrate.
    Type: Grant
