Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung einer Silicon-On-Insulator-Schichtstruktur auf einer Silizium-Oberfläche mit beliebiger Geometrie, mit dem die Silicon-on-Insulator-Struktur auch nur lokal erzeugt werden kann. Das Verfahren umfaßt das Bilden von Mesoporen (10) in dem Silizium-Oberflächenbereich (3), die Oxidation der Mesoporen-Oberfläche unter Bildung von Siliziumoxid und Stegbereichen (22) aus einkristallinem Silizium, die zwischen benachbarten Mesoporen (10) verbleiben, wobei dieser Schritt beendet wird, sobald eine vorgegebene minimale Silizium-Wandstärke der Stegbereiche (22) erreicht ist, das Freilegen der an dem von dem Halbleiter-Substrat (2) abgewandten Ende angeordneten Stegbereiche (22) zwischen benachbarten Mesoporen; und das Durchführen eines selektiven Epitaxieverfahrens, durch das Silizium auf den freigelegten Stegbereichen (22) selektiv gegenüber den Siliziumoxidbereichen (11) aufwächst. Das Verfahren kann verwendet werden, um einen vertikalen Transistor und eine Speicherzelle mit einem derartigen Auswahltransistor herzustellen.
