Claim 19:
20. A manufacturing method for a semiconductor apparatus, comprising:
bonding a semiconductor device to a lead frame;
forming a sealing member, after stacking in a mold, a metal base plate, an insulating layer, and the lead frame to which the semiconductor device is bonded, to seal the semiconductor device, the lead frame, the insulating layer, and the metal base plate in such a way that a portion of the lead frame and a portion of the metal base plate are exposed from the sealing member;
and, after inserting the portion of the metal base plate exposed from the sealing member into an opening of a support frame, welding a heat dissipating member having multiple fins formed by folding a metal plate to both the support frame and a part of the portion of the metal base plate exposed from the sealing member and inserted into the opening.
