Patent ID: 7319247

Claim:
A light-emitting diode chip, comprising: an electrically conductive substrate having a first substrate surface, a second substrate surface opposite the first substrate surface, and at least one side surface; a GaN-based radiation-emitting epitaxial layer sequence comprising an n-type epitaxial layer deposited on the first substrate surface and a p-type epitaxial layer deposited on the n-type epitaxial layer; a reflective, bondable p-contact layer comprising a first layer transmissive of radiation emitted by the epitaxial sequence and disposed on a side of the epitaxial layer sequence opposite the substrate and a second layer reflective of radiation emitted by the epitaxial sequence and disposed on the first layer; and a contact metallization disposed over only a portion of the second substrate surface, wherein radiation emitted by the epitaxial layer is decoupled through a portion of the second substrate surface over which the metallization is not disposed and through the substrate side surface.
