Abstract

Procedimento per la realizzazione di celle di memoria a sola lettura programmabili e cancellabili elettricamente a singolo livello di polisilicio la cui peculiarità consiste nel fatto di sfruttare uno strato sacrificale di ossido di silicio per realizzare uno strato di ossido di silicio su area attiva di elevato spessore e di proteggere l'area attiva della cella dell'impianto pesante di source e drain per migliorare l'affidabilità.
