Abstract:
Impact ionization in fully depleted (FD) Silicon On Insulator (SOI) n-Channel MOSFET is investigated as a function of the doping concentration. We have found that impact ionization increases with the decrease in the doping concentration and vice versa. Simulation results obtained from Sentaurus TCAD with the higher doping concentration can control the threshold voltage (Vth). Furthermore we have examined the effect of doping concentration on the transconductance (gm) and have observed that transconductance is inversely proportional of the doping concentration.

Abstract:
High temperature effects on the impact ionization of the n-channel fully depleted (FD) SOI MOSFET are investigated over a wide range of temperature from 300 to the 600 K by using TCAD. In particular, we have studied the current voltage characteristics (Id-Vd and Id-Vg ) , threshold voltage (Vth)and transconductance (gm). By the simulation results, we have analyzed that impact ionization decreases with increasing the temperature and vice versa. Furthermore, we have observed that threshold voltage and transconductance are both inversely proportional to the temperature.

Abstract:
This paper discusses linearity and robustness together for the first time, disclosing a way to improve them. It reveals that the nonlinear transconductance with device working at quasi-saturation region is significant factor of device linearity. The peak electric field is the root cause of electron velocity saturation. The high electric field at the drift region near the drain will cause more electron-hole pairs generated to trigger the parasitic NPN transistor turn-on, which may cause failure of device. Devices with different drift region doping are simulated with TCAD and measured. With LDD4

Abstract:
The article shows the practical implementation of the impurity freeze-out effect in the lightly-doped areas of the drain and source (LDD) in the Verilog-A model of the resistor. This model is based on a theoretical understanding of the freeze-out effect at cryogenic temperatures and data from the TCAD simulation of a MOSFET. The TCAD simulation data were represented by transconductance characteristics of n- and p-channel transistors Id(Vg) in linear mode (Vd=0.1 V) at temperature range from -200 °C to 27 °C for transistors with dimensions 10 um × 10 um.

The impact of work-function variation (WFV) on performance of an inversion-mode (IM) dual-metal gate (DMG) fin field-effect transistor (FinFET) was investigated for the first time. The statistical fluctuations induced by WFV on the threshold-voltage (VTH), transconductance (gm), and subthreshold slope (SS) were demonstrated and estimated utilizing a 3D technology computer-aided design (TCAD) simulator. We found that the performance variations of the DMG FinFET were affected by two different metals near the drain and near the source, respectively. Additionally, this effect of the two metals on

Abstract:
In this study, a heterodielectric BOX (HDB) Nanoribbon FET (NR-FET) is built using the TCAD device simulator to reduce the effect of trap charges on numerous electrical properties in traditional NR-FETs. Initially, a reasonable study in terms of transfer characteristics of NR-FET is highlighted between homodielectric and HD BOX. Because of the existence of high-k dielectric below the drain area, it is assumed that the impact of trap charges is insignificant in HDB NR-FET. Furthermore, the trap charge effect on transconductance (gm ), total gate capacitance (Cgg), and cut-off frequency (fc ) in
