  • Production of high radiance light emitting diodes
    Patent number: 4086126
    Abstract: For aligning holes in substrates with the light emitting regions of light emitting diodes, particularly Burrus type diodes, an etchant based on an alkaline peroxide solution is ejected or sprayed onto the masked surface of the substrate. The etchant is selective and also avoids production of insoluble oxides in partially etched holes, as often happens in conventional processes. The invention is particularly applicable to producing holes through substrates to align optical fibres with the light emitting regions.
