SEMICONDUCTOR DEVICE
A semiconductor device includes a semiconductor element, a conductive member, and solder portions. The semiconductor element includes first main electrodes and a protective film on a first main surface, and a second main electrode on a second main surface. The protective film has an interposed film portion between the first main electrodes. The conductive member has facing portions each facing a corresponding one of the first main electrodes and an interposed conductive portion disposed between the facing portions. The solder portions are disposed between the first main electrodes and the facing portions and separated away from each other by the interposed film portion and the interposed conductive portion to define a space between the solder portions. The interposed film portion and the interposed conductive portion are less likely wetted to the solder portions to avoid the solder portions in liquid phase entering into the space during soldering.
