1. A light-emitting diode with enhanced brightness, comprising:

  • an epitaxial LED structure having at least one light-emitting active layer and a highly doped layer, said highly doped layer having a plurality of windows formed therethrough;

    at least one conductive contact formed on a bottom surface of said highly doped layer;

    a transparent material layer formed in said windows;

    an adhesion layer formed between said transparent material layer and a permanent substrate;

    a bottom electrode formed on a bottom surface of said permanent an opposed electrode formed on a top surface of said epitaxial LED structure.
