Patent ID: 7642560

Claim:
A composite semiconductor light-emitting device comprising: a first semiconductor element portion including a nitride-based semiconductor material, said first semiconductor element portion having a first semiconductor layered structure, said first semiconductor element portion including a plurality of light-emitting regions that emit lights of different wavelengths, a second semiconductor element portion including a second semiconductor material different from said first semiconductor material, said second semiconductor element portion having a second semiconductor layered structure, said second semiconductor element portion including at least one light-emitting region that emits light whose wavelength is different from any of the lights emitted by said light-emitting regions, and a metal wiring extending on at least said first semiconductor element portion to electrically connect said light-emitting regions of said first semiconductor element portion and said at least one light-emitting region of said second semiconductor element portion, wherein said light-emitting regions of said first semiconductor element portion are composed of the same constituent material which is different from said at least one light-emitting region of said second semiconductor element portion.
