Abstract:
In an embodiment a component assembly includes a plurality of components, a carrier, wherein the components are secured on the carrier by a connecting layer, wherein, for each component, the connecting layer forms at least one supporting structure at which the connecting layer is adjacent to the component, and a sacrificial layer arranged regionally between the components and the connecting layer, wherein one portion of the components is assigned to a first group, wherein a further portion of the components is assigned to a second group, and wherein the components of the first group are different than the components of the second group in respect of a coverage with the sacrificial layer.
Abstract:
An optoelectronic component includes a first layer sequence being designed to emit or to detect electromagnetic radiation, and a second layer sequence being arranged at a first side of the first layer sequence and designed to reflect the electromagnetic radiation emitted or to be detected by the first layer sequence. The second layer sequence has a first reflector layer, a second reflector layer and an adhesion promoting layer. The first reflector layer contains a first material and is arranged at a first side of the second layer sequence facing the first side of the first layer sequence, the adhesion promoting layer contains a second material and is arranged at a second side of the second layer sequence facing away from the first side of the first layer sequence, and the second reflector layer contains the first material and is arranged between the first reflector layer and the adhesion promoting layer.
Abstract:
A method for producing an optoelectronic semiconductor chip is disclosed. In some embodiment the method includes arranging a metallic mirror layer on a top side of a semiconductor layer sequence, arranging a mirror protection layer at least on exposed lateral surfaces of the mirror layer in a self-aligning manner, wherein the mirror layer has openings toward the semiconductor layer sequence, and wherein the openings are framed in lateral directions by the mirror protection layer and partially removing the semiconductor layer sequence in a region of the openings of the mirror layer.
