Patent ID: 8586415

Claim:
A method of fixing a chipped work, comprising: providing a dicing/die-bonding film comprising a supporting base material; a pressure-sensitive adhesive layer formed on the supporting base material; and a die-bonding adhesive layer formed on the pressure-sensitive adhesive layer, said die-bonding adhesive layer being comprised of a work-attaching portion on which a work is to be attached and a no-work-attaching portion other than the work-attaching portion, said pressure-sensitive adhesive layer having a portion (a) corresponding to and adhering to the work-attaching portion and a portion (b) corresponding to and adhering contacting to the no-work-attaching portion, wherein adhesion of the portion (a) is lower than adhesion of the portion (b); pressing a work onto the work-attaching portion of the die-bonding adhesive layer of the dicing/die-bonding film; dicing the work into chips; releasing the chipped work together with the work-attaching portion of the die-bonding adhesive layer from the portion (a) of the pressure-sensitive adhesive layer; and fixing the chipped work to a semiconductor element via the work-attaching portion of the die-bonding adhesive layer, 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.
