  • Semiconductor light source and method for manufacturing a semiconductor light source
    Patent number: 10855051
    Abstract: What is shown is a method for manufacturing a semiconductor light source. The semiconductor light source has a substrate and a layer sequence arranged above the substrate, the same having a light-emitting layer and an upper boundary layer arranged above the light-emitting layer. The layer sequence is patterned in order to form a light-emitting stripe for defining the semiconductor light source and an alignment stripe, extending in parallel thereto, as a horizontal alignment mark at the same time. Then, a cover layer is applied on the patterned layer sequence and a part of the cover layer is removed in order to expose the alignment stripe and expose a region of the layer sequence outside the light-emitting stripe and spaced apart from a light-entrance edge or a light-exit edge of the light-emitting stripe as a vertical alignment mark.
