Abstract
LAS CAVIDADES DE FONDO PLANO SE FORMAN EN UN SUBSTRATO (2) MEDIANTE UN METODO QUE CONSTA DE DOS PASOS DE AGUAFUERTE: UN PRIMER AGUAFUERTE ANISOTROPICO A TRAVES DE UN MASCARON (4) QUE DEJA BANDAS EXPUESTAS (6, 8) DEL SUBSTRATO (2) Y UN SEGUNDO AGUAFUERTE ANISOTROPICO A TRAVES DE UN MASCARON QUE DEJA EXPUESTAS TODAS LAS ZONAS (Z1, Z2) PARA EL GRABADO. EL PRIMER AGUAFUERTE TIENE RANURAS EN V (10, 12) LA PROFUNDIDAD (X SUB 1, X SUB 2) DEL CUAL DEPENDE DE LA ANCHURA DE LAS BANDAS, MIENTRAS QUE EL SEGUNDO AGUAFUERTE AUMENTA LA PROFUNDIDAD DE LAS CAVIDADES EN IGUAL MEDIDA Y, AL ELIMINAR LAS BANDAS LOCALIZADAS ENTRE LAS RANURAS. VENTAJA: SE PUEDEN OBTENER CAVIDADES PLANAS DE DIFERENTES PROFUNDIDADES SIMULTANEAMENTE.
