ABSTRACT:
A process for producing semiconductor chips having a protective film on the back surface includes the steps of: providing a sheet to form the protective film having a release sheet and a protective film-forming layer formed on a detachable surface of the release sheet, wherein the protective film-forming layer includes a thermosetting component, an energy ray-curable component and a binder polymer component; adhering a protective film-forming layer of the sheet to form the protective film onto a back surface of a semiconductor wafer having circuits on its surface; curing the protective film-forming layer by irradiation with an energy ray, and thereafter, further conducting the additional steps of (in any order): detaching the release sheet from the protective film-forming layer; further curing the protective film-forming layer by heating; and dicing the semiconductor wafer together with the protective film-forming layer with respect to each circuit.
