<p>The invention provides an adhesive sheet for grinding a back surface of a semiconductor wafer, which is to be adhered to a circuit forming surface of the semiconductor wafer when the back surface of the semiconductor wafer is ground, in which the adhesive sheet contains an adhesive layer, an intermediate layer and a substrate in this order from the circuit forming surface side, the intermediate layer has a JIS-A hardness of more than 55 to less than 80, and the intermediate layer has a thickness of 300 to 600 µm. Furthermore, the invention also provides a method for grinding a back surface of a semiconductor wafer, including adhering the above-mentioned adhesive sheet to a circuit forming surface of the semiconductor wafer, followed by grinding the back surface of the semiconductor wafer.</p> |
