Comparison of Different High-k Dielectric Materials in MOS Device from C-V Characteristics

Abstract

In this paper different characteristic parameters using high-k dielectric materials in Metal Oxide Semiconductor (MOS) device have been compared from the theoretical and simulated Capacitance-Voltage (C-V) graphs. The simulation has been done using ATLAS device simulator. The agreement of the specified values while deriving and simulating and that extracted is excellent. Further, the extracted parameters for high-k dielectric materials show an inferior interfacial quality.
