Abstract

L'INVENTION SE RAPPORTE A L'AJUSTAGE OBTENU PAR CREATION D'ENTAILLES AU MOYEN D'UN FAISCEAU LUMINEUX FOCALISE, DE COMPOSANTS DISPOSES EN COUCHE MINCE OU EN COUCHE EPAISSE DEPOSEE SUR UNE COUCHE ISOLANTE DEPOSEE A LA SURFACE D'UN SUBSTRAT CONDUCTEUR. LE PROCEDE DE REGLAGE SELON L'INVENTION CONSISTE A DETERMINER L'ECHAUFFEMENT A PRODUIRE DANS LA COUCHE CONDUCTRICE PAR LE FAISCEAU LUMINEUX POUR ASSURER LE PERCAGE DE LA COUCHE CONDUCTRICE SANS PERCER EN MEME TEMPS LA COUCHE ISOLANTE. A CET EFFET, ON DEPOSE SUR LA COUCHE ISOLANTE UN OU PLUSIEURS ELEMENTS DE TEST SUR LESQUELS ON EFFECTUE DES MESURES EN FAISANT VARIER L'INTENSITE DE LA SOURCE LUMINEUSE, ETOU LA VITESSE DE TRACE DES ENTAILLES. LES VALEURS QUI SERONT UTILISEES POUR L'AJUSTAGE SONT CHOISIES ENTRE CELLES QUI PRODUISENT LE PERCAGE DE LA COUCHE CONDUCTRICE ET CELLES QUI PRODUISENT LE PERCAGE DE LA COUCHE ISOLANTE SOUS-JACENTE. L'INVENTION S'APPLIQUE A LA FABRICATION DES CIRCUITS REALISES EN COUCHE MINCE OU EPAISSE SUR DES SUBSTRATS CONDUCTEURS.
