Abstract: A method for fabricating a textured single crystal including depositing pads made of metal on a surface of a single crystal. A protective layer is deposited on the pads and on the single crystal between the pads; and etching the surface with a first compound that etches the metal more rapidly than the protective layer is carried out. Processing continues with etching the surface with a second compound that etches the single crystal more rapidly than the protective layer; and etching the surface with a third compound that etches the protective layer more rapidly than the single crystal. The textured substrate may be used for the epitaxial growth of GaN, AlN or III-N compounds (i.e. a nitride of a metal the positive ion of which carries a +3 positive charge) in the context of the fabrication of LEDs, electronic components or solar cells.
