LIGHT EMITTING DEVICE AND METHOD OF FORMING THE SAME
First Claim
1. A method of forming a light-emitting device, comprising:
- providing a temporary substrate having a multi-layer epitaxial structure and a first transparent conductive layer thereon;
cutting said temporary substrate to form a first dice comprising a portion of each of said multi-layer epitaxial structure, said first transparent conductive layer, and said temporary substrate;
providing a transparent substrate having a transparent adhesive layer on said transparent substrate;
attaching said first dice to said transparent adhesive layer; and
cutting said transparent substrate to form a second dice comprising said first dice, a portion of each of said transparent adhesive layer and said transparent substrate,wherein said transparent substrate of said second dice has a first surface facing said transparent adhesive layer and a second surface opposite to said first surface, the ratio of the area of said second surface to the area of a light-emitting layer of said second dice is not less than 1.6.

Abstract
A light-emitting device includes a transparent substrate, a transparent adhesive layer on the transparent substrate, a first transparent conductive layer on the transparent adhesive layer, a multi-layer epitaxial structure and a first electrode on the transparent conductive layer, and a second electrode on the multi-layer epitaxial structure. The multi-layer epitaxial structure includes a light-emitting layer. The transparent substrate has a first surface facing the transparent adhesive layer and a second surface opposite to the first surface, wherein the area of the second surface is larger than that of the light-emitting layer, and the area ratio thereof is not less than 1.6.
