Abstract (en)
[origin: WO2013127672A1] The invention relates to an optoelectronic semiconductor chip, comprising a plurality of active regions (1) that are arranged at a distance from each other and a substrate (2) that is arranged on an underside (1a) of the plurality of active regions (1), wherein one of the active regions (1) has a main extension direction (R), the active region (1) has a core region (10) that is formed using a first semiconductor material, the active region (1) has an active layer (11) that which covers the core region (10) at least in directions (x, y) perpendicular to the main extension direction (R) of the active region (1), and the active region (1) has a cover layer (12) that is formed using a second semiconductor material and covers the active layer (11) at least in directions (x, y) perpendicular to the main extension direction (R) of the active region (11).
