Patent ID: 11942756
Assignee: OSRAM OPTO SEMICONDUCTORS GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A radiation emitting semiconductor chip comprising:
a semiconductor layer sequence having at least two active regions, which generate electromagnetic radiation during operation,
at least one reflective outer surface arranged laterally of each active region, and
an electrically insulating region arranged between the active regions, wherein
the electrically insulating region has a reflective inner surface arranged opposite the reflective outer surface,
the reflecting inner surface includes an angle of at least 35° and at most 55° with a main extension plane of the semiconductor chip
the reflecting outer surface includes an angle of at least 35° and at most 55° with a main extension plane of the semiconductor chip and
a reflective coating is arranged on the semiconductor layer sequence in a region of the reflective outer surface and an anti-reflective coating is arranged on the semiconductor layer sequence in the electrically insulating region, or
an anti-reflective coating is arranged on the semiconductor layer sequence in the region of the reflective outer surface and a reflective coating is arranged on the semiconductor layer sequence in the electrically insulating region.
