| Zusammenfassung: | A semiconductor device is disclosed that includes a ceramic substrate having first and second surfaces, a semiconductor element, a radiator, and an interposed portion located between the second surface and the radiator. The interposed portion has coupling regions that couple the second surface to the radiator, and non-coupling regions that do not couple the second surface to the radiator. Each non-coupling region is formed as an elongated groove. In the group of the non-coupling regions, the width of the outermost non-coupling region in the interposed portion is greater than the width of the innermost non-coupling region in the interposed portion. Regarding an adjacent pair of the non-coupling regions in the width direction, the width of the outer non-coupling region is greater than or equal to the width of the inner non-coupling region. |
