Abstract

Masques de projection d'images électroniques convenant pour la fabrication des circuits intégrés et circuits à bulles magnétiques consistant en un masque optique classique portant de plus un revêtement transparent recouvrant le motif de masque et les régions du substrat exposées à travers les ouvertures du motif de masque. Ce revêtement transparent porte une image métallique dont le motif correspond aux ouvertures du motif de masque, la densité optique de l'image étant de nature à faire baisser la transmission lumineuse moyenne par les ouvertures du masque jusqu'à une valeur de 25 à 80 % de la transmission lumineuse moyenne par ces ouvertures en l'absence d'image métallique. Un tel masque permet d'engendrer le faisceau d'électrons voulu à l'aide d'une seule exposition à la lumière. Application : fabrication de circuits intégrés.
