Abstract
Es wird eine mikroelektronische Struktur mit einem verbesserten Schutz eines wasserstoffempfindlichen Dielektrikums vor einer Wasserstoffkontamination vorgeschlagen. Dazu ist vorgesehen, das wasserstoffempfindliche Dielektrikum (14) zumindest mit einem Zwischenoxid (18) zu bedecken, dessen Materialstärke mindestens das Fünffache der Dicke des wasserstoffempfindlichen Dielektrikums beträgt. Das Zwischenoxid (18) dient gleichzeitig als Intermetalldielektrikum, und trägt somit auf seiner Oberseite eine Metallisierung. Das ausreichend dicke Zwischenoxid (18) absorbiert den eventuell bei der Abscheidung einer Wasserstoffbarrierenschicht (22, 26) freiwerdenden Wasserstoff und schützt so das wasserstoffempfindliche Dielektrikum (14).
