| Zusammenfassung: | A submount on which a semiconductor device is mounted and which is mounted on a base made of metal, the submount including: a substrate; a first coating layer formed on a first surface of the substrate and made of a material having a higher coefficient of thermal expansion than that of the substrate; and a second coating layer formed on a second surface, positioned on a side opposite to the first surface, of the substrate and made of a material having a higher coefficient of thermal expansion than that of the substrate, in which a coating area of the second coating layer is smaller than a coating area of the first coating layer. |
