US 2022/0069170 A1 · LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME

Abstract

A light-emitting device includes: a light-emitting mesa structure having a first top surface and a peripheral surface connected to the first top surface; a transparent conductive layer that is disposed on the first top surface and that has a second top surface; a first insulating structure that is at least disposed on the peripheral surface and that has a third top surface and an inner tapered surface indented from the third top surface, the inner tapered surface having an acute angle with respect to the second top surface; and a reflective layer that is disposed on the transparent conductive layer and that has a first side surface in contact with the inner tapered surface. A method for manufacturing the light-emitting device is also disclosed.

A light-emitting device, comprising:

a light-emitting mesa structure having a first top surface and a peripheral surface connected to said first top surface;
a transparent conductive layer that is disposed on said first top surface of said light-emitting mesa structure and that has a second top surface;
a first insulating structure that is at least disposed on said peripheral surface of said light-emitting mesa structure and that has a third top surface and an inner tapered surface indented from said third top surface, said inner tapered surface having an acute angle with respect to said second top surface of said transparent conductive layer;
and
a reflective layer that is disposed on said transparent conductive layer and that has a first side surface in contact with said inner tapered surface of said first insulating structure.
