Patent ID: 8151856

Claim:
A surface protection film peeling device for peeling a surface protection film adhered to a front surface of a wafer, a dicing tape being adhered on a back surface of the wafer opposite to the front surface, the wafer being integrated with a mount frame into one body, comprising: a movable table configured to move horizontally to support the wafer and the mount frame while the surface protection film is being directed upward; a covering means for covering an adhesive face of the dicing tape, the dicing tape being exposed between the mount frame and the wafer at one end of the wafer, wherein an upper face of the covering means has a concaved slope; a moving means for moving the covering means and positioning the edge portion of the covering means below a top face of the mount frame in front of a boundary portion between the wafer and the surface protection film; and an adhering means for adhering a peeling tape to the surface protection film at the one end of the wafer, wherein the surface protection film is peeled away from the front surface of the wafer by moving the movable table in a direction towards the one end of the wafer, after the peeling tape has been adhered, and wherein a plurality of raised portions including a plurality of adjacent grooves extending in the movement direction of the movable table are formed on the concaved slope of the covering means from a distal end to a proximal end of the concaved slope along a width of the covering means.
