Patent ID: 7482696

Claim:
A light-emitting diode package structure, comprising: a semiconductor sub-mount having a first surface with a cavity therein and comprising a first conductive type semiconductor substrate and a second conductive type region enclosed by the first conductive type semiconductor substrate; a first patterned conductive-reflective film set up on a portion of the first surface, a first sidewall of the cavity and a bottom surface of the cavity, wherein the first patterned conductive-reflective film contacts with the first sidewall of the cavity and a part of the first conductive type semiconductor substrate; a second patterned conductive-reflective film set up on a portion of the first surface, a second sidewall of the cavity and a bottom surface of the cavity, wherein the second patterned conductive-reflective film covers the second sidewall of the cavity; an insulating layer only set up in-between the semiconductor sub-mount and the second patterned conductive-reflective film; and a light-emitting diode chip set up inside the cavity of the semiconductor sub-mount, wherein the light-emitting diode has a first electrode and a second electrode electrically connected to the first patterned conductive-reflective film and the second patterned conductive-reflective film.
