Abstract

L'INVENTION CONCERNE UN PROCEDE DE FORMATION D'UNE STRUCTURE MESA A PLUSIEURS ETAGES DANS UN SEMI-CONDUCTEUR. SELON L'INVENTION, DES PAROIS DE STRUCTURE MESA A PLUSIEURS ETAGES SONT FORMEES EN PRETRAITANT DES PORTIONS CHOISIES DU SEMI-CONDUCTEUR 110 QUI DOIVENT ETRE RETIREES POUR FORMER LA STRUCTURE MESA AFIN DE CHANGER LA VITESSE MOYENNE D'ENLEVEMENT DU MATERIAU PRETRAITE DANS L'ETAPE SUBSEQUENTE D'ENLEVEMENT; ON PROTEGE DES PORTIONS DE LA SURFACE DU MATERIAU SEMI-CONDUCTEUR PAR UN MASQUE 130, TANDIS QUE L'ON LAISSE SANS PROTECTION LES PORTIONS 122, 132 QUI DOIVENT ETRE RETIREES POUR FORMER LES PLATEAUX; ON EXPOSE LA PASTILLE DU SEMI-CONDUCTEUR A UNE SEULE ETAPE D'ENLEVEMENT QUI RETIRE LE MATERIEU PRETRAITE 118 A DES VITESSES DIFFERENTES DU MATERIAU NON PRETRAITE 116. L'INVENTION S'APPLIQUE NOTAMMENT A LA FORMATION DE TRANSISTORS.
