Abstract:
1. A method for manufacturing a semiconductor device in which a semiconductor element, a first electrode and a second electrode placed holding the semiconductor element from both sides, the first and second electrodes functioning as heat dissipating plates, and a block electrode placed between the semiconductor element and the first electrode are molded with resin, wherein the block electrode is integrally formed with one of the semiconductor device and the first electrode, and the block electrode is joined through solder to the other one of the first electrode and the block electrode, the other one being formed with no block electrode, the method includes the steps of: spraying metal powder onto the semiconductor element or the first electrode by a cold spray method to form the block electrode integrally with the one of the semiconductor element and the first electrode; and joining the block electrode to the other one of the first electrode and the semiconductor element through solder.
