Abstract
Aggressive scaling of Complementary Metal Oxide Semiconductor (CMOS) devices is driving SiO2 based gate dielectrics to its physical limits. Currently several alternative dielectric materials are being studied extensively as replacement for SiO2. This work mainly discusses charge trapping and the dielectric reliability of SiO2 / Al2O3 and SiO2 / HfO2 dual layer gate dielectrics. Due to the presence of transient charging / discharging effects measurement techniques down to the µs time range are being introduced.

| Aufgrund der raschen Miniaturisierung von komplementären Metall Oxyd Halbleiter (CMOS) Schaltkreisen werden die physikalischen Grenzen von Dielektrika auf SiO2 Basis in naher Zukunft erreicht. Verschiedene alternative dielektrische Materialien werden derzeit intensiv als Ersatz für SiO2 untersucht. In dieser Arbeit werden vorwiegend der Ladungseinfang und die Zuverlässigkeit von SiO2 / Al2O3 and SiO2 / HfO2 Schichten diskutiert. Aufgrund transienter Lade / Entladevorgänge werden schnelle Messverfahren im µs Bereich vorgestellt. | German |
