The objective of the present work is to study the effect of hot carrier damage/stress induced damage/process damage/radiation damage induced fixed charges at the semiconductor-oxide interface of the cylindrical nanowire MOSFET. Also the circuit reliability issues of the device are discussed in terms of the performance degradation due to interface fixed charges. The performance has been compared for the three materials in terms of drain current driving capability, I on /I off ratio, early voltage, transconductance, parasitic gate capacitance, intrinsic delay, current gain and power gain of the device.

The sensitivity is quantified in terms of relative change in the threshold voltage and sub-threshold drain current derived using the model. The impact of various device geometrical parameters (i.e. channel thickness, nanogap cavity length and thickness) on the sensitivity has been also been investigated. Moreover, two types of architecture: Nanogap embedded DG-FET with a nanogap cavity at the source/drain etched in the oxide and other with complete cavity over the channel length are analyzed through the model.
