Abstract

Matrice à semi-conducteurs pour mémoire permanente intégrée, réalisée à base d'éléments comportant une région semi-conductrice d'un premier type de conductivité, la région d'au moins une partie des éléments étant pourvue dans la couche présuperficielle d'une région semi-conductrice du second type de conductivité, lesdits éléments étant formés à l'intersection de barres semi-conductrices du premier type de conductivité, réalisées dans un substrat semi-conducteur, et de barres métalliques disposées sur une couche de diélectrique qui isole les barres semi-conductrices par rapport aux barres métalliques, tandis qu'au-dessus d'une partie des éléments dans la couche diélectrique, sont pratiquées au-dessus du second type de conductivité des ouvertures pour assurer le contact électrique entre lesdites régions du second type de conductivité et les barres métalliques, ladite matrice à semi-conducteurs étant caractérisée en ce que les barres semi-conductrices 4 comportent une couche supplémentaire 6 disposée entre le substrat 1 et la couche présuperficielle 5 et de même type de conductivité que ladite couche présuperficielle, la conductivité de la couche supplémentaire étant supérieure à la conductibilité de la couche présuperficielle et limitée par la solubilité limite de l'impureté de dopage dans le matériau d'une barre semi-conductrice.
