Abstract
The semiconductor device has a semiconductor structure directly bonded onto another semiconductor structure of a different kind from the former. These two semiconductor structures are arranged in such a way that their crystal structures in a cross section perpendicular to the bonded interface of the two semiconductor structures are different from each other or that their lattice orders are not equivalent. This can be applied to direct bonding of any combination of semiconductor structures in any crystallographic orientation relation. This also allows bonding of three or more kinds of semiconductor structures.
