摘要:
A light-emitting diode chip (1) with a semiconductor layer sequence (2) is described, which is contacted electrically by contacts (5) via a current spreading layer (3). The contacts (5) cover around 1%-8% of the surface of the semiconductor layer sequence (2). The contacts (5) consist for example of separate contact points (51), which are arranged at the nodes of a regular grid (52) with a grid constant of 12 μm. The current spreading layer (3) contains for example indium-tin oxide, indium-zinc oxide or zinc oxide and has a thickness in the range from 15 nm to 60 nm.
