Development of energy efficient next generations of Silicon Carbide (SiC) power MOSFETs is necessary to meet a growing demand for SiC technology from a wide range of applications that includes electric vehicles, solar inverters, power supplies, industrial motor drives and energy storage etc. Success of R&D efforts critically depends on ability to perform predictive TCAD simulations of SiC power MOSFETs. Although significant progress has been made in TCAD modelling of 4H-SiC, we observe that the existing set of models needs further improvements and calibration.
In this presentation, we focus on the bulk mobility model for 4H-SiC. We observe that the temperature dependence of bulk resistivity cannot be predicted accurately using the popular mobility models. A careful investigation reveals that these mobility models need to be revised and replaced by a comprehensive model that can describe the impurity scattering effects dominant at low temperatures. We present a well calibrated bulk mobility model for 4H-SiC exhibiting excellent agreement with measured data, making it suitable for device simulation purposes using TCAD tools.

Performance predictions of nanodevices ideally include 1) atomistic resolution, 2) a consistent description of all quantum phenomena, and 3) a realistic treatment of incoherent scattering on phonons and impurities. It is common believe that atomistic quantum transport either entails unfeasible numerical load or neglects scattering effects altogether. Victory Atomistics indeed covers all 3 aspects, and this presentation showcases new modeling features in the realm of 2D materials and carbon nanotubes.
While Victory Atomistic covers all those points for only a small fraction of the typical numerical costs, some of the atomistic simulations might still take a few CPU hours to finish. Therefore, Silvaco’s and Purdue’s teams are bridging the gap between atomistic simulations and TCAD to enable reliable simulation results in TCAD typical simulation times.

The traps characterization based on the lateral and vertical device of growth GaN material on other substrates and results in high density of threading dislocation (the order of >108 cm-2). In order to improve the threading dislocation, previously; patterned-sapphire substrates (PSS) or nano patterned-sapphire substrates (NPSS) that can elevate the device optical/electrical characteristics, replace the plane-sapphire and the expensive SiC/free-standing GaN substrates. Using the TCAD simulation, resulting the traps affect the device performances within leakage current, hard-breakdown voltage, switch turn on/off, and especially the reliability issues. In addition, commercially, the productions of GaN-on-Silicon (Si) power device focuses on horizontal structures high electron mobility transistor (HEMT) with current collapse phenomenon to modify Epi-structures by TCAD.

Standard cells are form the lowest level foundation in the hierarchy of modern chip design architectures. FinFET technologies have enabled designs with increased density and performance while reducing power, when compared to traditional planar layouts. However, the transition to FinFET technologies has come at the cost of increased standard cell design rule complexity. Many design rules violations can no longer be fixed within a local scope, since they may span a large region of a cell and interact with many layers, negatively impacting productivity for both initial design, migration and opportunities for specialization of standard cell libraries. In this talk we are going to review some of the most challenging aspects of FinFET standard-cell layout design, and how Silvaco Cello FinFET can be used to meet these challenges.

Photodiodes are a key technology to many growing application areas. Automotive vision systems, Advanced industrial machinery, and high-speed communications systems all rely on photodiodes to link optical inputs into usable electrical signal.
In this talk Silvaco will discuss these technologies, and how TCAD can be broadly applied to multiple detector topologies/material sets and thus multiple end-user markets. Additionally, we’ll detail simulation and analysis of an InGaAs Avalanche Photodiode. Through this demonstration, it will be shown how TCAD can be used to explore and characterize diode performance and extracting key Figures of Merit. Through TCAD, photodiode designers and technologists can increase their device performance, while decreasing engineering manufacturing and test cycles.

This talk covers two extremely important aspects related to the design and simulation of Flat Panel Displays: 4-terminal TFT devices, and image retention.
Many TFT technologies in the market today are based on 4-terminal devices. In contrast, the SPICE simulators from other vendors can only support 3-terminal TFT compact models. Silvaco’s 4-terminal TFT model is unique in the market, and we will present some of the characteristics of this compact model, and some of the degrees of freedom that it brings to both modeling and the design teams.
Additionally, image retention is a long-standing issue in the display community. To effectively solve this issue, or even to minimize its impact on their products, display manufacturers and consumer electronics vendors need to simulate this effect at the SPICE level. We describe how SmartSpice Flex Modeling technology can be used to simulate image retention issues. This solution, which is unique to Silvaco, can model any dynamic device effects in SPICE simulation.

The back-end-of-line (BEOL) compatible amorphous oxide semiconductor (AOS) thin-film transistor (TFT) is a suitable technology platform for the development of monolithic three-dimensional integrated circuits (M3D-ICs). In this work, n-channel amorphous indium tungsten oxide (a-IWO) nanosheet transistors have been successfully demonstrated in the class of InOx-based TFTs, especially with channel thickness scaling down to 4 nm. The integration of a-IWO nanosheet TFT with HfO2 gate insulator exhibits low operation voltages, good electrical characteristics: near ideal subthreshold swing ~ 63mV/dec., high field-effect mobility ~ 25.3 cm2/V-s. Through TCAD analysis, the effects of oxygen flow during a-IWO thin-film deposition on oxygen interstitials (Oi) defect at the front channel were numerically proved, validating the proposed physical mechanisms with a quantum model for a-IWO nanosheet TFT.
