Abstract:
1. A dicing/die-bonding film comprising a pressure-sensitive adhesive layer on a supporting base material and a die-bonding adhesive layer on the pressure-sensitive adhesive layer, wherein the die-bonding adhesive layer is arranged as a work-attaching region on a part of the pressure-sensitive adhesive layer, and a region (a) corresponding to the work-attaching region in the pressure sensitive adhesive layer and a region (b) other than the region (a) are different in adhesion and satisfy the relationship: the adhesion of the region (a) is lower than the region (b), wherein adhesion of said region (a) of the pressure-sensitive adhesive layer is 0.01 to 0.5 N/20 mm and the adhesion of said region (b) of the pressure-sensitive adhesive layer is 0.5 to 20 N/20 mm.
