Abstract

Un processo di realizzazione su semiconduttori di regioni impiantate a basso rischio di channeling, del tipo applicato a dispositivi elettronici a semiconduttore aventi almeno uno strato di silicio policristallino (7) ricoprente sia regioni (5) di isolamento, sia aeree (4) attive sensibili al fenomeno di channeling, prevede la successione delle seguenti fasi:- Mascheratura delle aree o regioni (8) da impiantare sullo strato (7) policristallino;- Impiantazione di una prima specie drogante avente elevato peso atomico, con conseguente amorfizazzione del silicio policristallino nelle aree prive di mascheratura;- Rimozione della mascheratura e successiva fase di impiantazione su tutto il semiconduttore di una seconda specie drogante.Ciò consente di ottenere una amorfizzazione selettiva delle sole zone sovrastanti un area attiva, quelle cioè in cui il fenomeno di channeling potrebbe essere dannoso.
