Patent attributes
A peeling apparatus peels a protective member off a wafer, the protective member including a resin and a film which is fixed to one surface of the wafer with the resin interposed therebetween. The film has a protrusive marginal side extending radially outwardly beyond an outer circumferential edge of the wafer. A holding unit holds another surface of the wafer with the protective member disposed therebelow. A gripping unit grips the protrusive marginal side of the protective member. A peeling mechanism peels the protective member off the wafer by relatively moving the gripping unit and the holding unit radially inwardly from the outer circumferential edge of the wafer toward the center of the wafer. A camera then captures an image of the wafer, and a decision unit determines whether residue of the resin remains on the wafer from the image captured by the camera.
