Patent ID: 8907359

Claim:
An optoelectronic semiconductor component comprising a semiconductor layer sequence based on a nitride compound semiconductor and containing an n-doped region, a p-doped region and an active zone arranged between the n-doped region and the p-doped region, wherein the p-doped region comprises a p-doped contact layer composed of In x Al y Ga 1-x-y N where 0≦x≦1, 0≦y≦1 and x+y≦1, which adjoins a connection layer composed of a metal, a metal alloy or a transparent conductive oxide, and wherein the p-doped contact layer has first domains having a Ga-face orientation and second domains having an N-face orientation at an interface with the connection layer, wherein the p-doped contact layer is doped with magnesium, wherein the p-doped contact layer has a dopant concentration of between 5*10 19 cm −3 and 2*10 21 cm −3 inclusive, and wherein the p-doped contact layer has a thickness of between 5 nm and 200 nm, inclusive, and further wherein the p-doped contact layer has an area proportion of at least 10% and at most 90% of domains having Ga-face orientation at the interface with the connection layer.
