Abstract:
1. An adhesive film for manufacturing a semiconductor device comprising a thermosetting adhesive layer having an elastic modulus of from 1×10 2 to 1×10 5 Pa at 120° C. before curing, and an elastic modulus of 1 MPa or more at 200° C. after curing and a heat-resistant backing layer, wherein said adhesive film can be used for manufacturing a semiconductor device comprising the steps of: (a) embedding at least a part of a conductor in the adhesive film to form a conductor adhered thereto; (b) mounting a semiconductor chip on the conductor; (c) connecting the semiconductor chip to the conductor; (d) encapsulating the semiconductor chip with an encapsulation resin to form an assembly comprising at least said adhesive film, said conductor, said semiconductor chip and said encapsulation resin; and (e) removing the adhesive film from said assembly.
