We simulate the capacitance-voltage (C-V) characteristics of the MOS devices with ultrathin oxide using ATLAS, a commercially available TCAD tool from SILVACO. The tool has investigated the effect on C-V characteristics of different oxide thickness and doping concentration of SiO2 and HfO2 as insulators and Si and SiC as semiconductor based MOS devices. Excellent agreement was observed over a wide range of oxide thickness and substrate doping for the materials. The C-V characteristics of different polytype of SiC semiconductor also studied for n-type MOS devices.
