Patent ID: 8704257

Claim:
A light-emitting element comprising: a light-emitting stack for emitting light; a transparent conductive layer disposed below the light-emitting stack; an ohmic contact layer disposed between the light-emitting stack and the transparent conductive layer; a substrate structure disposed under the light-emitting stack comprising: a first substrate disposed under the light-emitting stack and having a first surface facing the light-emitting stack; and a second substrate being a transparent substrate, disposed under the light-emitting stack, and having at least a second surface facing the light-emitting stack; and a reflective layer formed between the first substrate and the second substrate and having an inclined angle not perpendicular to the first surface to reflect the light from the light-emitting stack, wherein the second surface of the second substrate is discontinuous in cross-section; and a bonding structure formed between the substrate structure and the transparent conductive layer, wherein the bonding structure comprises a first conductive-attaching layer formed on the substrate structure and a second conductive-attaching layer formed on the bottom of the transparent conductive layer and wherein the bonding structure is offset laterally from the ohmic contact layer.
