发明名称 Laminated sheet
摘要 A laminated sheet for adhering to a circuit side of a projected electrode-mounting wafer in a step of grinding a backside of the wafer, wherein the laminated sheet comprises at least a layer (layer A) contacting with the circuit side, made of a thermosetting resin, a layer (layer B) directly laminated on the layer A, made of a thermoplastic resin having a tensile modulus of from 1 to 300 MPa at 40° to 80° C., and an outermost layer (layer C) made of a thermoplastic resin which is non-plastic at a temperature of at least 25° C.; A method for manufacturing a semiconductor device, comprising the steps of grinding a backside of a projected electrode-mounting wafer wherein the laminated sheet is adhered to a circuit side of the wafer, removing other layers besides the layer A of the laminated sheet, and cutting the wafer into individual chips; and a semiconductor device obtainable by the method.
