Patent ID: 8410513

Claim:
A light emitting device package comprising: a first conductive type package body; an insulating layer comprising a first opening on a top surface of the package body; a plurality of compound semiconductor layers disposed on the package body through the first opening of the insulating layer; an electrode electrically connected to the plurality of compound semiconductor layers; a first metal layer electrically connected to the package body and disposed on a part of the insulating layer; a second metal layer electrically connected to the electrode and disposed on the other part of the insulating layer; and a protection device disposed on the package body, the protection device electrically connected to the first metal layer and the second metal layer, wherein the plurality of compound semiconductor layers comprises a conductive type buffer layer disposed on the top surface of the package body, wherein the conductive type buffer layer contacts the top surface of the package body, wherein the conductive type buffer layer is formed of a semiconductor doped with a first conductive type dopant, and wherein the protection device comprises: a first well connected to the first metal layer, the first well having a polarity opposite to that of the package body; and a second well connected to the second metal layer at a portion of the first well, the second well having the same polarity as the package body.
