Abstract:
A method of fabricating a light emitting diode device comprises providing a substrate, growing an epitaxial structure on the substrate. The epitaxial structure includes a first layer on the substrate, an active layer on the first layer and a second layer on the active layer. The method further comprises depositing a conductive and reflective layer on the epitaxial structure, forming a group of first trenches and a second trench. Each of the first and second trenches extends from surface of the conductive and reflective layer to the first layer to expose part of the first layer. The method further comprises depositing conductive material to cover a portion of the conductive and reflective layer to form a first contact pad, and cover surfaces between adjacent first trenches to form a second contact pad. The second contact pad electrically connects the first layer by filling the conductive material in the first trenches.
Abstract:
An LED device with improved LED efficiency is presented. A top surface of a circuit board carrying the LED die is covered with a reflective layer. The reflective surface on top of the circuit board allows the light reflected off a surface of a waveguide to be recycled by being redirected back to the waveguide.
Abstract:
An LED device with improved LED efficiency is presented. An LED die is positioned within a pocket formed by a substrate and an opening in a supporting layer arranged thereon. The increase in the LED efficiency is achieved by providing a device where at least a portion of the pocket surface is reflective. This portion of the pocket surface is reflective because it is covered by either a reflective layer of foil or film, or a reflective coating, or it is polished.

Abstract:
A light emitting diode and its fabricating method are disclosed. A light emitting diode epitaxy structure is formed on a substrate, and then the light emitting diode epitaxy structure is etched to form a recess. The recess is then filled with a transparent dielectric material. An adhesive layer is utilized to adhere a conductive substrate and the light emitting diode epitaxy structure. Next, the substrate is removed.

A method for processing an edge of a photovoltaic panel is described. A first electrically-conductive film, a photovoltaic film and a second electrically-conductive film are serially formed as a stack of three films over a surface of a substrate. An edge section of the stack of three films is removed from the surface of the substrate by sandblasting. At least two separate grooves are formed by laser scribing on all the three films adjacent to the removed edge section of the stack of three films.
