Abstract
A radiation-emitting semi-conductor chip has a substrate and a semiconductor body arranged on the substrate and with a semiconductor layer sequence that includes an active region provided for producing radiation, an n-type region, and a covering layer arranged on a side of the n-type region that faces away from said active region. There is a contact structure arranged on the covering layer for the external electrical contacting of the n-type region. The covering layer has at least one recess through which the contact structure extends to the n-type region.
