Abstract

UN METODO PARA FABRICAR UNA CAPA DE OXIDO TUNEL DE GRAN CALIDAD INCLUYE UN PROCESO DE OXIDACION EN DOS ETAPAS. LA PRIMERA ETAPA DE OXIDACION CONSISTE EN OXIDAR UN SUBSTRATO EN UNA ATMOSFERA QUE CONTIENE OXIGENO Y NITROGENO A UNA TEMPERATURA DE 900 (GRADOS) C APROXIMADAMENTE, Y ASI ES UNA OXIDACION SIN HCL. LA SEGUNDA ETAPA DE OXIDACION SE LLEVA A CABO EN UNA ATMOSFERA QUE CONTIENE HCL Y ARGON A UNA TEMPERATURA DE 1050 (GRADOS) C APROXIMADAMENTE. LA PRIMERA ETAPA DE OXIDACION SE LLEVA A CABO A UNA TEMPERATURA EN EL INTERVALO DE TEMPERATURAS DEL FLUJO VISCOSO DEL OXIDO PARA EVITAR CUALQUIER DEFECTO FISICO DE LA FORMA DE LA CAPA DE OXIDO. LA SEGUNDA ETAPA DE OXIDACION SE LLEVA A CABO A UNA TEMPERATURA SUFICIENTE PARA PASIVAR CUALQUIER ION MOVIL EN LA CAPA DE OXIDO EN UNA ATMOSFERA QUE CONTIENE UN AGENTE ENGENDRADOR, POR EJEMPLO HCL. MEDIANTE ESTE PROCESO DE OXIDACION EN DOS ETAPAS SE FABRICA UNA CAPA DE OXIDO TUNEL QUE ES DE GRAN CALIDAD Y NO SE DETERIORA DURANTE LAS ETAPAS DE PROCESADO SUBSIGUIENTES LLEVADAS A CABO A TEMPERATURAS DE HASTA 1100 (GRADOS) C Y SUPERIORES.
