Atomistic TNL TCAD simulators:

 TNL Framework: TNL Framework includes family of innovative simulators based on atomistic level. It provides innovative technology solution to semiconductor industry. The technology development is expensive process and suffers with lot of technical challenges & issues. TNL framework is designed to innovate the semiconductor device designing. It accommodate atomistic based thin film growth simulator, full band simulator, material characterization simulator and Monte Carlo particle device simulator. 

 EpiGrow Simulator: EpiGrow simulator is world's first commercial innovative atomistic epitaxial growth simulator to grow thin film inside MBE/MOCVD reactors. EpiGrow simulator is powerful tool to trace atomistic thin and thick film growth inside reactors. Kinetic Monte Carlo algorithms keeps Randomness in adsorption, hopping & desorption processes. It offer cost economical solution for thin film growth technology even for nm thin monolayer.

Different types of physical parameters e.g. carrier velocity, effective mass and density of states can be easily tracable on the full electronic band structures of the chosen materials. Provides flexibility to users to chose lattice constant and analyse the full electronic band structures over computer.

 TNL-EM Simulator: Electron Mobility Simulator is powerful tool, simulates carriers transport on full energy band. The microscopic simulation of the motion of individual particles in the presence of the forces acting on them due to external fields as well as the internal fields of the crystal lattice and other charges in the system. In solids, such as semiconductors and metals, transport is known to be dominated by random scattering events due to impurities, lattice vibrations, etc. has been inputted through Monte Carlo technique, which randomize the momentum and energy of charge particles in time. Hence, stochastic techniques to model these random scattering events are particularly useful in describing transport in semiconductors, in particular the Monte Carlo method. Provides flexibility to users to initialize the carriers over full energy band and analyze the transport of carrier to simulate the ensemble velocity of carriers under external electromagnetic forces on computer.

 TNL-TS (THz Spectroscopy) Simulator is powerful tool to simulates motion of charged and interacting particles. The microscopic simulation of the motion of individual particles under the influence of the THz pulse as well as the internal fields of the crystal lattice and influence of other charges, lattice defects etc. In solids, such as semiconductors and metals, transport is known to be dominated by random scattering events due to impurities, lattice vibrations, etc., which randomize the momentum and energy of charge particles in time. The stochastic techniques to model these random scattering events are particularly useful in describing inter and intraband transitions of charge carriers in bulk & nonmaterial. The Monte Carlo technique use for solution of Boltzmann transport equation provides flexibility to users to initialize the carriers over many or particular band of the material and analyze the position, momentum, energy & other properties associated with motion of charged particles under influence of THz Pulses, frequencies ranging from few hundred gigahertz to several terahertz. THz Spectroscopy simulator has capabilities to simulate the microscopic conductivity of weakly confined, classical electrons in absence of depolarization effects without need of any approximations of fitting parameters to calibrate the Drude-Smith conductivities..

 TNL-PD Simulator: World's Fastest Monte Carlo Particle Device simulator includes transport model solution with a self -consistent Boltzmann-Poisson equation and a GUI based feature helps users to select device geometry and doping density in 2D and 3D. The different carrier scattering mechanisms has major influence on the performance of device output and dependent on the density of states (DOS) in each valley which can be accurately inputted through full band structure. The effect of equilibrium states of carrier before start of free flight of carrier has been incorporated in term of inclusion of depletion region through movement of the ensemble of carriers under influence of external electrostatic field obtained by solving the Poisson equation. The quantum confinement effect includes density gradient approach and effective potential approach for computation of quantum confinement effects on the carrier transport under influence of external forces. Particle Device Simulator (PDS) is exploited for unipolar as well as bipolar semiconductor technologies based devices including MOSFET, Multigate FETS, HEMT and P-N junction devices.

[paper] Compact Model for SiC Power MOSFETs

A Compact Model for SiC Power MOSFETs 
for Large Current and High Voltage Operation Conditions

Abstract: This work presents a physics based compact model for SiC power MOSFETs that accurately describes the I-V characteristics up to large voltages and currents. Charge-based formulations accounting for the different physics of SiC power MOSFETs are presented. The formulations account for the effect of the large SiC/SiO2 interface traps density characteristic of SiC MOSFETs and its dependence with temperature. The modeling of interface charge density is found to be necessary to describe the electrostatics of SiC power MOSFETs when operating at simultaneous high current and high voltage regions. The proposed compact model accurately fits the measurement data extracted of a 160 milli ohms, 1200V SiC power MOSFET in the complete IV plane from drain-voltage Vd = 5mV up to 800 V and current ranges from few mA to 30 A.
Fig: Output characteristics up to high current and high voltage in logarithmic scale for VGS = 6V to 20V in steps of 0.5V. Symbols are measurements and solid lines simulations of the proposed model. The logarithmic scale eases the visualization of both low and high VDS voltages in a single graph.
