Assignee: OSRAM OLED GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A radiation-emitting semiconductor chip comprising:
a semiconductor body comprising an active region configured to generate electromagnetic radiation;
a reflector configured to reflect a portion of the electromagnetic radiation; wherein the semiconductor body extends beyond the reflector in a lateral direction;
at least one cavity;
a supporting layer arranged on an underside of the reflector facing away from the semiconductor body; wherein the supporting layer comprises a top side, a bottom side opposite the top side, and two sidewalls adjacent to the top side and the bottom side; wherein the top side faces the underside of the reflector;
at least one support arranged between the reflector and the semiconductor body; wherein the at least one support is a metal material or a transparent conductive oxide; and wherein when the at least one support is a metal material, then the reflector has the same material as the at least one support; and
a seal impermeable to the material;, wherein the at least one cavity is arranged between the reflector and the semiconductor body, wherein the seal covers the underside of the reflector, wherein the seal contacts a portion of the semiconductor body that extends beyond the reflector in the lateral direction; and wherein the seal laterally surrounds the supporting layer and at least partially covers at least one side wall of the supporting layer,, wherein the at least one support imparts the at least one cavity as a singular gap absent of solid material and located between the semiconductor body and the reflector, and wherein the support comprises columns or posts situated within the singular gap.
