Patent ID: 8159000

Claim:
A light-emitting diode package, comprising: a heat sink; a nitride semiconductor light-emitting chip arranged on a top side of the heat sink, a first surface of the nitride semiconductor light-emitting chip comprising a first type nitride semiconductor layer, a semi-insulating layer, or an insulating nitride semiconductor layer, a second surface of the nitride semiconductor light-emitting chip comprising a second type nitride semiconductor layer and a concave cut-out region, the first type nitride semiconductor layer being exposed in the concave region; a package body coupled with the heat sink, a bottom side of the heat sink not being covered by the package body; a lead frame coupled with the package body, the lead frame being spaced apart from the heat sink and protruding from the package body; a substrate arranged between the heat sink and the nitride semiconductor light-emitting chip; a passivation layer arranged between the substrate and the nitride semiconductor light-emitting chip; a plurality of electrode patterns arranged between the substrate and the nitride semiconductor light-emitting chip; and a bonding pad arranged at an edge of the substrate, wherein the bottom side of the heat sink and a portion of the lead frame are coplanar, and wherein inner walls of the package body comprise a stepped portion.
