US 2025/0160073 A1 · SEMICONDUCTOR LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME

Abstract

Provided is a semiconductor light emitting device capable of performing bonding of a phosphor plate and a light emitting element in the atmosphere by surface activated bonding. A semiconductor light emitting device includes a light emitting element including a semiconductor light emitting layer, and a phosphor plate bonded to the light emitting element. A buffer layer formed of a dielectric that transmits light emitted by the light emitting element is disposed between the light emitting element and the phosphor plate. The light emitting element and the phosphor plate are bonded with the buffer layer interposed therebetween. The buffer layer is amorphous.
