Abstract
In one embodiment, the invention relates to an optoelectronic semiconductor chip comprising a semiconductor layer sequence. The semiconductor layer sequence has an n-conducting first layer region, a p-conducting second layer region and an active zone lying therebetween for generating radiation. The second layer region comprises a first subregion directly adjacent to the active zone, the first subregion being composed of p-conducting InvAl1-vP. The second layer region also comprises a second subregion directly adjacent to the first subregion, the second subregion having p-conducting Iny(GaxAl1-x)1-yP. The second layer region also comprises a third subregion as a p-contact layer directly adjacent to the second subregion.
