Abstract:
1. A manufacturing method of a semiconductor device comprising the steps of: (a) providing a semiconductor wafer having a first principal surface, a plurality of chip regions provided on the first principal surface, a cutting region provided between mutually adjacent chip regions, and a second principal surface on the side opposite to the first principal surface; (b) after the step (a), placing the semiconductor wafer on a front surface of a first support heated to a first temperature so that the first principal surface of the semiconductor wafer faces the front surface of the first support, and bonding a film-like adhesive sheet to the second principal surface of the semiconductor wafer in a state where heat has been applied to the semiconductor wafer; (c) after the step (b), applying a second temperature higher than the first temperature to the semiconductor wafer having the adhesive sheet bonded thereto; (d) after the step (c), cutting the semiconductor wafer and the adhesive sheet along one or more of the cutting regions, and obtaining a semiconductor chip having an adhesive patch bonded thereto; (e) after the step (d), placing the semiconductor chip on an upper surface of a mother substrate with the adhesive patch facing the upper surface to thereby fix the semiconductor chip to the upper surface of the mother substrate, the mother substrate including a metal and being arranged on a front surface of a second support heated to a third temperature; (f) after the step (e), electrically coupling an electrode pad of the semiconductor chip and an external terminal of the mother substrate via a conductive member; (g) after the step (f), forming a sealing body by sealing with resin the semiconductor chip, the adhesive patch, and the upper surface of the mother substrate; and (h) after the step (g), peeling off the mother substrate from the sealing body, and exposing a back surface of the adhesive patch from the sealing body.
