Abstract
An optoelectronic semiconductor chip includes a contact layer that impresses current directly into a first semiconductor region present in direct contact with a current web, the first semiconductor region is an n-side and a second semiconductor region is a p-side of a semiconductor layer sequence, and a second mirror layer is applied directly to a second semiconductor region, a plurality of contact fields and isolator fields are arranged alternately along a longitudinal direction of the current web, in the contact fields, the contact layer is in direct contact with the current web, and the isolator fields are free of the contact layer, and a first mirror layer is located between the current web and the first semiconductor region.
