Abstract:
A method of fabricating a light-emitting apparatus comprising:depositing a layer of reflective material on a surface of a light-generating device; forming a diffusion barrier on said layer of reflective material such that said layer of reflective material is positioned between said diffusion barrier and said light-generating device, said diffusion barrier being a single layer of uniform material composition; depositing a layer of soldering material on said diffusion barrier so that said layer of reflective material and said layer of soldering material are physically separated by said diffusion barrier; placing said light-generating device with said layer of reflective material, said diffusion layer and said layer of soldering material on a mounting surface such that said layer of soldering material is in contact with said mounting surface; and melting said layer of solder material to attach said light-generating device to said mounting surface.
