Abstract

Procédé de fabrication de transistors. On utilise ici les techniques dites de décollement pour obtenir une couche 30 de blocage d'ions recouvrant l'une des parois en pentes douces d'une ouverture située dans une couche de SiO2 déposée sur un substrat semi-conducteur 2. Soumettant ensuite l'élément ainsi obtenu, à une implantation ionique, on obtient une couche uniforme 34 dont l'un des bords, 38, est abrupt, l'autre, 36, en pente douce. Fabrication de semi-conducteurs.
