Patent ID: 7383869

Claim:
A film peeling device for peeling a film which has been stuck onto a film sticking face of a wafer, comprising: a wafer sucking means for sucking the wafer so that the film sticking face of the wafer can become an upper face; a peeling tape feeding means for feeding a peeling tape onto the film of the film sticking face; a pushing means for pushing only one portion of the peeling tape against the film of the wafer at an edge portion of the wafer so that an adhesive strength between the peeling tape and the film can be enhanced in the one portion of the peeling tape; and a peeling means for peeling the film from the film sticking face of the wafer by the peeling tape while the one portion of the peeling tape, the adhesive strength of which has been enhanced, is used as a peeling start portion, wherein the pushing means includes a pushing roller moving in a substantially transverse direction of the peeling tape, wherein the one portion of the peeling tape is pushed when the pushing roller moves on the one portion of the peeling tape, wherein the pushing means includes a rotatable disk, wherein the pushing roller is attached to a lower face of the rotatable disk in such a manner that the rotary axis of the pushing roller can be located on the radius of the rotatable disk, and the pushing roller is moved along an arc on the peeling tape when the rotatable disk is rotated, and wherein an auxiliary roller is attached to the lower face of the rotatable disk, and the auxiliary roller pushes the film of the wafer located at a position where the peeling tape does not exist.
