    摘要: Radiation-emitting semiconductor device, method for fabricating same and radiation-emitting optical device. A radiation-emitting semiconductor device with a multilayer structure (100) comprising a radiation-emitting active layer (10), with electrical contacts (30, 40) for impressing a current in the multilayer structure (100) and with a radiotransparent window layer (20). The window layer is arranged exclusively on the side of the multilayer structure (100) facing away from a main direction of radiation of the semiconductor device and has at least one side wall that includes a first side wall portion (20a) which extends obliquely, concavely or in a stepwise manner toward a central axis of the semiconductor device lying perpendicular to the multilayer sequence. In its subsequent extension toward the back side, viewed from the multilayer structure, the side wall changes over into a second side wall portion (20b) that extends perpendicularly to the multilayer structure, that is, parallel to the central axis, and the portion of the window layer (20) encompassing the second side wall portion (20b) forms a mounting pedestal for the semiconductor device. The first and second side wall portions are fabricated especially preferably by means of a saw blade having a shaped edge. In a preferred optical device, the semiconductor device is mounted window layer downward in a reflector cup.

    摘要: A semiconductor component includes a semiconductor body with a semiconductor layer sequence having an active region, provided for generating coherent radiation, and an indicator layer. With respect to an interface which delimits the semiconductor body in regions in a vertical direction, on that side of said interface which is remote from the active region, the semiconductor body has a web-like region extending in a vertical direction between the interface and a surface of the semiconductor body. The indicator layer has a material composition that differs from that of the material of the web-like region which adjoins the indicator layer. A distance between the indicator layer and the surface is at most of the same magnitude as a distance between the interface and the surface.
