Abstract
A radiation-emitting semiconductor chip (1) having a semiconductor layer sequence (3) comprising at least one active layer (2) that generates an electromagnetic radiation, and having a passivation layer (12) arranged on the radiation-emerging side of the semiconductor layer sequence (3), it being possible to set the degree of transmission of the semiconductor chip by means of the passivation layer.
Claims15
A radiation-emitting semiconductor chip (1) having a semiconductor layer sequence (3) comprising at least one active layer (2) that generates an electromagnetic radiation, and having a passivation layer (12) arranged on the radiation-emerging side of the semiconductor layer sequence (3),
- wherein
- the passivation layer (12) is partly absorbent, it being possible to set the degree of transmission for the radiation emitted by the semiconductor layer sequence during operation of the semiconductor chip (1) during the production of the passivation layer (12).
A radiation-emitting semiconductor chip (1) having a semiconductor layer sequence (3) comprising at least one active layer (2) that generates an electromagnetic radiation, and having a passivation layer (12) arranged on the radiation-emerging side of the semiconductor layer sequence (3),
- wherein
- the passivation layer (12) comprises a brightness setting layer (22), which, during operation of the semiconductor chip (1), absorbs part of the electromagnetic radiation generated in the chip.
