A semiconductor chip which emits electromagnetic radiation is presented. The chip includes an epitaxially produced semiconductor layer stack based on nitride semiconductor material, which includes an n-conducting semiconductor layer, a p-conducting semiconductor layer, and an electromagnetic radiation generating region, which is arranged between these two semiconductor layers. The chip further includes a base on which the semiconductor layer stack is arranged, and a mirror layer, which is arranged between the semiconductor layer stack and the base. The n-conducting semiconductor layer faces away from the base, and the n-conducting semiconductor layer or an outcoupling layer located on the n-conducting semiconductor layer has a radiation-outcoupling surface which, in turn, includes planar outcoupling sub-surfaces, which are positioned obliquely with respect to a main plane of the radiation-generating region and each form an angle of between 15.degree. and 70.degree. with this plane.
