Embodiments of the invention include a light emitting diode including a semiconductor structure including an active layer disposed between an n-type region and a p-type region. The active layer emits UV radiation. A first metal layer is in direct contact with the p-type region. A second metal layer is in direct contact with the n-type region. The first and second metal layers are both formed on a first side of the semiconductor structure. A transparent optic is optically coupled to a major surface of the light emitting diode.

Package for ultraviolet emitting devices

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.

Ultraviolet disinfection system

Sputtering apparatus and method suitable for forming a step coating on a workpiece. A workpiece is supported in a chamber, particles are emitted from a sputtering source, and the particles are passed through a collimating filter having a plurality of transmissive cells positioned between the sputtering source and the workpiece to limit the angles at which the particles can be deposited onto the workpiece. The collimating filter varies in height from a center portion to an outer portion while preferably maintaining a constant cell aspect ratio.
