Abstract
A silicon carbide semiconductor device includes a substrate, a drift layer, a base layer, a first electrode, and a second electrode. The substrate includes a cell region at which a semiconductor element is disposed and a temperature detection region at which a diode element is disposed. The first electrode is disposed at a side facing the substrate with the drift layer sandwiched between the substrate and the first electrode. The second electrode is disposed at a side facing the drift layer with the substrate sandwiched between the drift layer and the second electrode. The semiconductor element includes a first impurity region and a second impurity region disposed at a surface layer portion of the base layer. The diode element includes a first constituent layer at a surface layer portion of the base layer and a second constituent layer connected to the first constituent layer.
