Abstract

SE DESCRIBE UN METODO PARA PRODUCIR GRANDES CRISTALES INDIVIDUALES.SE PRODUCE UN CRISTAL INDIVIDUAL DE DIAMANTE DE GRADO ELECTRONICO CON UN GROSOR DE 100-1000 MICRONES Y UN AREA SUSTANCIALMENTE MAYOR DE 1 CM2 Y QUE TIENE UNA ALTA PERFECCION CRISTALINA, QUE PUEDE SER UTILIZADO EN APLICACIONES MECANICAS OPTICAS ,ELECTRONICAS U OTRAS.UNA LAMINA DE DIAMANTE CRISTALINO SE DEPOSITA PRIMERO SOBRE UN CRISTAL PRINCIPAL EN GRANO Y LAS LAMINAS DE DIAMANTE RESULTANTES SE PUEDEN SEPARAR DEL CRISTAL EN GRANO POR MEDIOS FISICOS MECANICOS Y QUIMICOS.EL CRISTAL PRINCIPAL PUEDE RESTAURARSE POR CRECIMIENTO EPITAXIAL CON SU USO REPETIDO COMO CRISTAL EN GRANO EN POSTERIORES OPERACIONES.SE PUEDE LOGRAR UN GRAN CRISTAL PRINCIPAL DE DIAMANTE EN GRANO AL COMBINAR LOS PEQUEÑOS CRISTALES EN GRANO ORIENTADOS POR FUSION EPITAXIAL LATERAL.DESDE AQUI NO HAY LIMITE DE VECES EN QUE SE PUEDEN REPETIR LOS PASOS DE COMBINACION DEL CRISTAL.SE PUEDEN FABRICAR GRANDES SECTORES DE DIAMANTE COMPARABLES EN TAMAÑO A LOS DE SILICONA.
