Abstract
A method of thinning the substrate under the junctions has been developed to improve the extraction of light through the front surface of LED´s. This new technique has been applied to diodes made by Ga(AsP):N / GaP and Ga(AsP) / GaAs technologies. An increase in efficiency of a factor 3 is demonstrated. A simple theoretical model is presented.
