Abstract:
1. A light-emitting diode, comprising: a bonding substrate comprising a first surface and a second surface on opposite sides; a first conductivity type electrode disposed on the second surface of the bonding substrate; a bonding layer disposed on the first surface of the bonding substrate; an epitaxial structure including a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer stacked on the bonding layer in sequence, wherein the first conductivity type semiconductor layer and the second conductivity type semiconductor layer have different conductivity types, and a trench is set around the epitaxial structure and extends from the second conductivity type semiconductor layer to the first conductivity type semiconductor layer; a second conductivity type electrode electrically connected to the second conductivity type semiconductor layer; and a growth substrate disposed on the epitaxial structure, wherein the growth substrate comprises a cavity exposing a portion of the epitaxial structure and the trench.
