Zusammenfassung:In a method for manufacturing a semiconductor device, a plurality of first provisional fixing portions are supplied on a front surface of a substrate such that the plurality of first provisional fixing portions are spaced from each other and thus dispersed. A first solder layer processed into a plate to be a first soldering portion is disposed in contact with the plurality of first provisional fixing portions. A semiconductor chip is disposed on the first solder layer. In addition a conductive member in the form of a flat plate is disposed thereon via a second provisional fixing portion and a second solder layer. A reflow process is performed to solder the substrate, the semiconductor chip and the conductive member together.
