Abstract:
1. A submount substrate for mounting a light emitting device, comprising: a substrate doped with first polar impurities; a diffusion layer formed by second polar impurities, having a polarity different from that of the first polar impurities, injected and diffused into a top surface of the substrate, and the diffusion layer being divided into two parts by a substrate region with no diffusion region formed thereon; an insulating layer formed on a top surface of the substrate and having a first opening through which a part of one divided region of the diffusion layer is exposed and a second opening through which a part of the substrate region with no diffusion region formed thereon is exposed; a first electrode line formed on a top surface of the insulating layer and connected to the diffusion layer through the first opening; and a second electrode line connected to the substrate region through the second opening.
