Abstract
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.
