Abstract
Provided are a circuit connecting material able to provide good bonding with an opposing electrode, and a semiconductor device manufacturing method using the same. The present invention uses a circuit connecting material, in which a first adhesive layer to be adhered to the semiconductor chip side, and a second adhesive layer having a lowest melting viscosity attainment temperature higher than that of the first adhesive layer are laminated. When the semiconductor chip on which the circuit connecting material is stuck is mounted on a circuit board, a thickness of the first adhesive layer is within a range satisfying formula (1), thereby providing good bonding with the opposing electrode.
