摘要:
An LED and manufacturing method therefor. The LED comprises a compound semiconductor structure having first and second compound layers and active layer, first and second electrode layers atop the second compound semiconductor layer and connected to the two compound. An insulating layer is coated in regions other than where the first and second electrode layers are located. A conducting adhesive layer is formed atop the non-conductive substrate, connecting the same to the first electrode layer and insulating layer. Formed on one side surface of the non-conductive substrate and adhesive layer is a first electrode connection layer connected to the conducting adhesive layer. A second electrode connection layer on the other side surface is connected to the second electrode layer.

A semiconductor light-emitting device, and a method of manufacturing the same. The semiconductor light-emitting device includes a first electrode layer, an insulating layer, a second electrode layer, a second semiconductor layer, an active layer, and a first semiconductor layer that are sequentially stacked on a substrate, a first contact that passes through the substrate to be electrically connected to the first electrode layer, and a second contact that passes through the substrate, the first electrode layer, and the insulating layer to communicate with the second electrode layer. The first electrode layer is electrically connected to the first semiconductor layer by filling a contact hole that passes through the second electrode layer, the second semiconductor layer, and the active layer, and the insulating layer surrounds an inner circumferential surface of the contact hole to insulate the first electrode layer from the second electrode layer.
