Abstract:
1. A wafer arrangement, comprising: two wafers placed one on top of the other; and a contact area between planar surfaces of the two wafers; wherein: the two wafers are connected to one another at selected connection areas of the contact area, at least one of the two wafers is a silicon wafer, a germanium wafer, a gallium arsenide wafer, an InP wafer, a ceramic wafer or a GaP wafer, a mechanical joint between the two wafers is mediated or effected by a material between the planar surfaces of the two wafers, wherein said material is applied as a continuous layer entirely covering the planar surfaces of the two wafers in the contact area, wherein the contact area comprises connection-free areas arranged therein where there is no mechanical joint between the two wafers, at least one of the two wafers comprises two or more individual layers, and at least one of the two or more individual layers is an epitaxially applied layer comprising an active layer configured to produce or to detect radiation, and wherein at least one of the two or more individual layers is part of an optoelectronic component.
