Abstract
A semiconductor device includes: a first element formed of a first constituent as a main constituent; a second element formed of a second constituent as a main constituent; a heat sink on which the first element and the second element are disposed; a first connection layer electrically connecting the first element to the heat sink; a second connection layer electrically connecting the second element to the heat sink; and a mold resin covering and protecting the first element, the second element and the heat sink. Sizes of the first element and the second element are set so that an equivalent plastic strain increment of the first connection layer is greater than the second connection layer. Accordingly, in the semiconductor device including semiconductor elements formed of different constituents, the elements are thermally protected without providing a temperature detector to the semiconductor element formed of one of the constituents.
