Abstract:
Disclosed is an optoelectronic semiconductor chip (10) comprising: —a succession of semiconductor layers (1) that has a main plane of extension, an active layer (12) and a bottom surface (1c); —a substrate (41) that is arranged on the bottom surface (1c) of the succession of semiconductor layers (1) and has a base surface (41c) facing away from the bottom surface (1c); and —a succession of joining layers (3) which is arranged in at least some locations between the succession of semiconductor layers (1) and the substrate (41) in a vertical direction; wherein —the substrate (41) laterally protrudes from the succession of semiconductor layers (1) by a maximum of 10 μm.
