Patent ID: 7052934

Claim:
A method for fabricating a semiconductor device, the method comprising: a reinforcing step of bonding a reinforcing plate, via an adhesive layer, on a front surface of a semiconductor wafer bearing one or more semiconductor devices, the reinforcing plate having one or more holes that connect a front surface and a back surface of the reinforcing plate; a grinding step of grinding a back surface of the semiconductor wafer; a bonding step of bonding a dicing tape on the back surface of the semiconductor wafer after said grinding; a detaching step of detaching the reinforcing plate from the semiconductor wafer by injecting through said one or more holes a solvent for dissolving the adhesive layer; a dicing step of dicing the semiconductor wafer so as to separate the semiconductor devices into individual pieces, said bonding step being carried out after said grinding step and before said detaching step, said dicing step being carried out after said detaching step; and wherein, in said detaching step, a side surface of the adhesive layer is covered with a jig before the solvent is injected into said one or more holes.
