Abstract
An optoelectronic semiconductor device may include a carrier having a roughened first main surface and optoelectronic semiconductor chips arranged over the roughened first main surface. The combined surface area of the optoelectronic semiconductor chips is smaller than the surface area of the carrier, and a part of the roughened first main surface is arranged between adjacent optoelectronic semiconductor chips.
