  • Solid State Light Emitting Device
    Publication number: 20090159869
    Abstract: A semiconductor structure (10, 10?, 70, 80) includes a light emitter (12, 72) carried by a support structure (11). The light emitter (12, 72) includes a base region (24, 76) with a sloped sidewall (12a, 12b) and a light emitting region (25, 77) positioned thereon. The light emitting (25, 77) region includes a nitride semiconductor alloy having a composition that is different in a first region (26, 95) near the support structure (11) compared to a second region (27, 96) away from the support structure (11).
