Claim Text:
1. A semiconductor device comprising: a semiconductor element having a first face and a rear face opposite to the first face, the first face including a solder region for soldering and a non-solder region not for soldering, the rear face being for soldering; a first metal member disposed on the first face of the semiconductor element; a second metal member disposed on the rear face of the semiconductor element; a first solder that connects the solder region of the semiconductor element and the first metal member; and a second solder that connects the rear face of the semiconductor element and the second metal member, wherein: at least the second solder provides a melt-bond in the semiconductor device, in which the semiconductor element is stacked on the second metal member through the second solder, and the first metal member is stacked on the semiconductor element through the first solder; and a gravity center position of the first metal member coincides with a center position of the semiconductor element in a projection view from a stacking direction.
