Title:
OPTOELECTRONIC SEMICONDUCTOR COMPONENT
Document Type and Number:
WIPO Patent Application WO/2015/189056
Kind Code:
A3
Abstract:
Disclosed is an optoelectronic semiconductor component (1) comprising a semiconductor body (2) that has a sequence of semiconductor layers including an active region (20) provided for generating radiation, a semiconductor layer (21) and another semiconductor layer (22); the active region is located between the semiconductor layer and the other semiconductor layer; a current spreading layer is disposed on a radiation exit surface (210) of the semiconductor body; the current spreading layer is connected in an electrically conducting manner to a contact structure (4) for electrically contacting the semiconductor layer externally; from a bird's eye view of the semiconductor component, the current spreading layer borders the semiconductor layer in a connecting region (30); and the current spreading layer has a structure (31) that includes a plurality of recesses (35) through which radiation exits the semiconductor component during operation.
