  • Publication number: 20190157498
    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.
    Type: Application

  • Patent number: 8049242
    Abstract: An optoelectronic device such as a light-emitting diode chip is disclosed. It includes a substrate, a multi-layer epitaxial structure, a first metal electrode layer, a second metal electrode layer, a first bonding pad and a second bonding pad. The multi-layer epitaxial structure on the transparent substrate comprises a semiconductor layer of a first conductive type, an active layer, and a semiconductor layer of a second conductive type. The first bonding pad and the second bonding pad are on the same level. Furthermore, the first metal electrode layer can be patterned so the current is spread to the light-emitting diode chip uniformly.
