Abstract
An organic adhesive light-emitting device with an ohmic metal contact, including a conductive substrate having a first surface and a second surface over the upper surface, a light-emitting stack layer, an ohmic metal bulge formed over the first surface of the conductive substrate, a reflection layer formed over the light-emitting stack layer, a first reaction layer formed over the ohmic metal bulge and the second surface of the conductive substrate, a second reaction layer formed over the reflection layer, and an organic adhesive material. The reaction layer can punch through the organic adhesive material for forming the ohmic contact with the first reaction layer bonded to the second reaction layer by the organic adhesive material, and with the ohmic metal bulge.
