Abstract:
Disclosed herein is a protective tape attaching method for attaching a protective tape to a wafer, the protective tape having a size corresponding to the size of the wafer. The protective tape attaching method includes: a bending step of bending a release paper to which an adhesive layer of the protective tape is previously attached, stretching the release paper to peel a front end portion of the protective tape from the release paper, and attaching the front end portion of the protective tape to the wafer; and an attaching step of pressing the other side of the protective tape opposite to the adhesive layer by using a pressure roller to thereby bring the adhesive layer of the protective tape into close contact with the wafer after performing the bending step.

Claim (Index 2):
A protective tape attaching apparatus for attaching a protective tape to a wafer, said protective tape having an adhesive layer formed on one side, said adhesive layer having adhesion to be reduced by applying ultraviolet light, said protective tape having a size corresponding to the size of said wafer, said protective tape attaching apparatus comprising:\n holding means for holding said wafer; sheet feeding means for feeding a sheet from a protective tape roll, said sheet being composed of a release paper and said protective tape, said adhesive layer of said protective tape being previously attached to said release paper, said protective tape roll being previously formed by rolling said sheet; release paper winding means for winding said release paper; bending means for bending said release paper, stretching said release paper in cooperation with said sheet feeding means and said release paper winding means to peel a front end portion of said protective tape from said release paper, and attaching said front end portion of said protective tape to said wafer held by said holding means; attaching means for pressing the other side of said protective tape opposite to said adhesive layer by using a pressure roller to thereby bring said adhesive layer of said protective tape into close contact with said wafer, and further stretching said release paper in cooperation with said sheet feeding means and said release paper winding means to fully peel said protective tape from said release paper and attach the whole of said protective tape to said wafer; and ultraviolet applying means for previously applying said ultraviolet light to said front end portion of said protective tape to thereby reduce the adhesion of said adhesive layer of said front end portion before operating said bending means, thereby forming a peeling start point where peeling of said protective tape from said release paper is started, at said front end portion of said protective tape.
