摘要:
A method for producing an optoelectronic semiconductor chip based on a nitride semiconductor system is specified. The method comprises the steps of: forming a semiconductor section with at least one p-doped region; and forming a covering layer disposed downstream of the semiconductor section in a growth direction of the semiconductor chip, said covering layer having at least one n-doped semiconductor layer. An activation step suitable for electrically activating the p-doped region is effected before or during the formation of the covering layer. An optoelectronic semiconductor chip which can be produced by the method is additionally specified.
