Abstract
A light-emitting semiconductor chip is provided, the semiconductor chip comprising a semiconductor body having a pixel region with at least two electrically isolated sub-regions, each sub-region comprising an active layer, which generates electromagnetic radiation of a first wavelength range during operation, a separately manufactured ceramic conversion die over a radiation emission area of at least one sub-region, said conversion die being configured to convert radiation of the first wavelength range into electromagnetic radiation of a second wavelength range, wherein a width of the conversion die does not exceed 100 μm. Further, a method for the production of a light-emitting semiconductor chip and method for the production of a conversion die are provided.
