Claim 4:
5. A method for producing a semiconductor device including:
cutting the semiconductor processing adhesive tape according to claim 1 along an outer circumference of a semiconductor wafer which is adhered with the semiconductor processing adhesive tape;
forming a groove from a front surface side of the semiconductor wafer or forming a modified region inside the semiconductor wafer from the front surface or a back surface of the semiconductor wafer;
dicing the semiconductor wafer, of which the adhesive tape is adhered on the front surface and the groove or the modified region is formed, using the groove or the modified region as a starting point for forming a plurality of chips by grinding from the back surface; and
releasing the semiconductor processing adhesive tape from the plurality of chips.
