Claim Text:
1. A thin-film Light Emitting Diode (LED), comprising: a substrate; a first electrode formed on the substrate; a second electrode; an epitaxial layer positioned between the first electrode and the second electrode and configured such that an electrical potential applied between the first electrode and the second electrode cause a portion of the active volume to emit light of a predetermined wavelength, wherein the epitaxial layer is provided with a proton implantation that destroys a crystalline structure of the epitaxial layer in selected locations to create an active volume having an area smaller than a total area of the epitaxial layer; and a passivation layer positioned over the active volume and being configured to at least one of: reduce reflection at an LED-air interface and protect material of the epitaxial layer from an environment surrounding the thin-film LED.
