Abstract:
A dicing die attachment film includes a die attachment layer attached to one surface of a semiconductor wafer; a dicing film layer attached to a dicing die that is used for cutting the semi-conductor wafer into die units; and an intermediate layer laminated between the die attachment layer and the dicing film layer. The intermediate layer has a modulus of 100 to 3000 MPa, which is greater than a modulus of the die attachment layer and the dicing film layer.
