Claim Text:
1. A method of manufacturing a semiconductor device, comprising the steps of: placing, on a heat sink made of a metal, a semiconductor element and a frame surrounding the semiconductor element; placing solder on an upper surface of the frame; placing a cap on the solder and the frame to thereby create, in a first region, a direct abutment between the cap and the frame, and, in a second region, an arrangement in which the solder is positioned between the cap and the frame, wherein the first region is positioned between the second region and the semiconductor element; and heating step for heating the solder while exerting on the cap a force to be applied toward the frame without scrubbing the cap on the frame; wherein in the heating step a heat source is brought into contact with the heat sink and the solder is heated with the heat source, and wherein the abutment between the cap and the frame in the first region prevents the solder from intruding from the second region into an interior of the semiconductor device.
