Abstract:

This report investigates the advantages of high-k materials as gate dielectrics for high power SiC trench MOSFET devices, by means of TCAD simulation. The study makes a comparison between the breakdown characteristics of gate dielectrics comprising SiO2, HfO2 and TiO2. I-V and Transfer functions show forward characteristics with on-state resistivity of 8.27 m*⋅cm2, 8.65 m*⋅cm2, 15.8 m*⋅cm2 for the respective devices, at a gate voltage of 20 V. The threshold voltage is 10 V for all devices. The blocking voltage for the HfO2 and TiO2 is increased from 1800 V (for the SiO2 device) to 2200 V. With

Abstract:

The mechanism of threshold voltage shift was studied. It is believed that the instability in threshold voltage during gate bias stress is due to capture of electrons by the SiC/gate dielectric interface traps and the gate dielectric near interface traps. New experimental platform was designed and built successfully. When positive stress or negative stress is applied to the gate, the change of threshold voltage occur immediately. After stress removal, the recovery of the threshold voltage occur soon. The change and recovery of threshold voltage are very sensitive to time. In order to get accura

An Analytical study for the surface potential, threshold voltage and Subthreshold swing (SS) of Dual-metal Gate Graded channel and Dual Oxide Thickness with two dielectric constant different cylindrical gate surrounding-gate (DMG-GC-DOTTDCD) metal–oxide–semiconductor field-effect transistors (MOSFETs) is proposed to investigate short-channel effects (SCEs). The performance of the modified structure was studied by developing physics-based analytical models for the surface potential, threshold voltage shift, and Subthreshold swing.

Abstract:

Operation of SiC MOSFETs beyond 300°C opens up opportunities for a wide range of CMOS based digital and analogue applications. However the majority of the literature focuses only on the optimization of a single type of MOS device (either PMOS or more commonly NMOS) and there is a lack of a comprehensive study describing the challenge of optimizing CMOS devices. This study reports on the impact of gate oxide performance in channel implanted SiC on the electrical stability for both NMOS and PMOS capacitors and transistors. Parameters including interface state density (Dit), flatband voltage (VFB

Abstract:

In this paper, we have analyzed the effect of chiral vector, temperature, metal work function, channel length and High-K dielectric on threshold voltage of CNTFET devices. We have also compared the effect of oxide thickness on gate capacitance and justified the advantage a CNTFET provides over MOSFET in nanometer regime. Simulation on HSPICE tool shows that high threshold voltage can be achieved at low chiral vector pair in CNTFET. It is also observed that the temperature has a negligible effect on threshold voltage of CNTFET. After that we have simulated and observed the effect of channel len

Abstract:

Gate oxide reliability measurements of 4H-SiC DMOSFETs were performed using the Time Dependent Dielectric Breakdown (TDDB) technique at 175°C. The oxide lifetime is then plotted as a function of the electric field. The results show the projected oxide lifetime to be > 100 years at an operating field of ~3 MV/cm. Device reliability of 2.0 kV DMOSFETs was studied by stressing the gate with a constant gate voltage of +15 V at a temperature of 175°C, and monitoring the forward I-V characteristics and threshold voltage for device stability. Our very first measurements show very little variation

Abstract:

In this paper, an analytical threshold voltage model of double gate-all-around metal-oxide-semiconductorfield-effect-transistors (DGAA MOSFETs) including the fringing field effects is developed. The total fringing capacitance arising due to induced fringing fields in the device is divided into inner, outer and bottom fringing capacitance. A simple expression for each fringe capacitance is developed individually. The 3-D Poisson's equation has been solved in the channel region using the parabolic potential approximation method to develop the surface potential expressions. The effects of fringin

Abstract:

AbstractThe quest for high device density in advanced technology nodes makes strain engineering increasingly difficult in the last few decades. The mechanical strain and performance gain has also started to diminish due to aggressive transistor pitch scaling. In order to continue Moore’s law of scaling, it is necessary to find an effective way to enhance carrier transport in scaled dimensions. In this regard, the use of alternative nanomaterials that have superior transport properties for metal-oxide-semiconductor field-effect transistor (MOSFET) channel would be advantageous.

Abstract:

The performance and characteristics of Double Gate MOSFET with high dielectric constant (high-κ) gate stack have been analyzed and compared with those of conventional pure SiO2gate MOSFET. Quantum Ballistic Transport Model has been used to demonstrate the performance of the device in terms of threshold voltage, drain current in both low and high drain voltage regions and subthreshold swing. The effect of temperature on the threshold voltage and subthreshold characteristics has also been observed. This work reveals that improved performance of this structure can be achieved by scaling the gate

Abstract:

This work deals with the assessment of gate dielectric for 4H-SiC MOSFETs using technology based two-dimensional numerical computer simulations. Results are studied for variety of gate dielectric candidates with varying thicknesses using well-known Fowler-Nordheim tunneling model. Compared to conventional SiO2as a gate dielectric for 4H-SiC MOSFETs, high-kgate dielectric such as HfO2reduces significantly the amount of electric field in the gate dielectric with equal gate dielectric thickness and hence the overall gate current density. High-kgate dielectric further reduces the shift in the thre

Abstract:

Progress in advanced microlithography and deposition techniques have made feasible high- k dielectric materials for MOS transistors. The continued scaling of CMOS devices is pushing the Si-SiO2 to its limit to consider high-k gate dielectrics. The demand for faster, low power, smaller, less expensive devices with good functionality and higher performance increases the demand for high-k dielectric based MOS devices. This thesis gives an in-depth study of threshold voltages of PMOS and NMOS transistors using various high-k dielectric materials like Tantalum pent oxide (Ta2O5), Hafnium oxide (HfO

Abstract:

This work describes computer simulations of various, Silicon on Insulator (SOI) Metal Oxide Semiconductor Field Effect Transistor (MOSFETs) with double and triple-gate structures, as well as gate-all-around devices. To explore the optimum design space for four different gate structures, simulations were performed with four variable device parameters: gate length, channel width, doping concentration, and silicon film thickness. The efficiency of the different gate structures is shown to be dependent of these parameters. Here short-channel properties of multi-gate SOI MOSFETs (MuGFETs) are studi
