Patent ID: 7223319

Claim:
A semiconductor manufacturing apparatus comprising: a peeling mechanism to peel a pressure sensitive adhesive (PSA) tape from a semiconductor wafer, the semiconductor wafer having an element formation surface to form an element thereon, and a rear surface opposite to the element formation surface, and an adhesive layer formed on the entire rear surface, and a sealing resin formed on the element formation surface and a low dielectric constant insulation film formed on the sealing resin, the PSA tape adhering to the element formation surface of the semiconductor wafer via the sealing resin and the low dielectric constant insulation film, wherein said peeling mechanism has a sucking section which has a porous member to hold the semiconductor wafer and a cutting device to cut the adhesive layer, said porous member being segmented into at least two sucking areas in a direction in which the PSA tape is peeled; and a heating device to fuse at least part of the low dielectric constant insulation film and the sealing resin so as to fix the low dielectric constant insulation film on the sealing resin, wherein said heating device fuses at least part of the low dielectric constant insulation film and the sealing resin by applying laser to a peripheral edge of the semiconductor chip with an incidence angle of 20° to 40°.
