Dicing/die-bonding film, method of fixing chipped work and semiconductor device
Abstract:
A dicing/die-bonding film including a pressure-sensitive adhesive layer (2) on a supporting base material (1) and a die-bonding adhesive layer (3) on the pressure-sensitive adhesive layer (2), wherein a releasability in an interface between the pressure-sensitive adhesive layer (2) and the die-bonding adhesive layer (3) is different between an interface (A) corresponding to a work-attaching region (3a) in the die-bonding adhesive layer (3) and an interface (B) corresponding to a part or a whole of the other region (3b), and the releasability of the interface (A) is higher than the releasability of the interface (B). The dicing/die-bonding film is excellent in balance between retention in dicing a work and releasability in releasing its diced chipped work together with the die-bonding adhesive layer.
