    Abstract: Embodiments of the invention include a first semiconductor layer grown over a growth substrate and a plurality of pixels grown on the first semiconductor layer, each pixel including an active layer disposed between an n-type region and a p-type region. Trenches isolate individual pixels and form at least one sidewall for each pixel. A first metal layer in direct contact with the p-type region is disposed on a top surface of each pixel. A second metal layer in direct contact with the n-type region is disposed on a bottom surface of a trench adjacent to each pixel. An insulating layer electrically isolating the first and second metal layers is disposed on the sidewall of each pixel and is substantially conformal to the sidewall.

    Abstract: Embodiments of the invention include a light emitting diode (LED) including a semiconductor structure. The semiconductor structure includes an active layer disposed between an n-type region and a p-type region. The active layer emits UV radiation. The LED is disposed on the mount. The mount is disposed on a conductive slug. A support surrounds the conductive slug. The support includes electrically conductive contact pads disposed on a bottom surface, and a thermally conductive pad disposed beneath the conductive slug, wherein the thermally conductive pad is not electrically connected to the LED.

    Abstract: Embodiments of the invention include an elongate chamber. A UV source includes a semiconductor device, the semiconductor device including an active layer disposed between an n-type region and a p-type region. The active layer emits radiation having a peak wavelength in a UV range. The semiconductor device is positioned on a wall of the elongate chamber. An inner surface of the elongate chamber is reflective.
