Abstract

[Problem] To provide a dicing sheet that is with a protective film formation layer, can easily produce a semiconductor chip having a protective film having high uniformity and superior printing precision, is such that the peeling of the protective film and the dicing sheet can be easily performed, and has superior affixing ability of chips during dicing. [Solution] The dicing sheet with a protective film formation layer is characterized by a protective film formation layer being peelably provided on the adhesive layer of an adhesive sheet resulting from the adhesive layer, which contains an adhesive component and a free epoxy group-containing compound, being laminated onto a substrate film.
