Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the design, characterization, modeling and analysis of high voltage Silicon Carbide (SiC) metal-oxide-semiconductor field effect transistors (MOSFET), insulated gate bipolar transistors (IGBT) and emitter turn-off thyristors (ETO) to satisfy the stringent requirements of advanced power electronic systems. The loss information, frequency capability and switching ruggedness of these 10-kV SiC power devices are studied extensively in order to provide their application prospects in solid-state transformers (SST). Among 10-kV SiC power devices, SiC MOSFETs are of the greatest interest due to their lower specific on-resistance compared to silicon MOSFETs, and their inherently fast switching speed due to their majority carrier conduction mechanism. Therefore, 10-kV SiC MOSFETs are studied first in this dissertation. The characterization, modeling and analysis of 10-kV SiC MOSFETs were investigated extensively. The low losses and high switching frequency of 10-kV SiC MOSFETs were demonstrated in characterization study and a 4-kV 4 kW boost converter. The on-resistance of SiC MOSFETs increases rapidly with increased junction temperature and blocking voltage. This makes their conduction losses possibly unacceptable for applications where high DC supply voltages (more than 10-kV) and high temperature operation are used. This warrants the development of SiC bipolar devices (IGBTs and thyristors) to achieve smaller conduction losses due to the conductivity modulation of their thick drift layers, especially at elevated temperatures. Therefore, design, characterization and optimization of 10-kV SiC IGBT and ETO were dicussed. A 4H-SiC p-channel IGBT with improved conduction characteristics was developed and characterized experimentally as well as analyzed theoretically by numerical simulations. The device exhibited a differential on-resistance of 26 mOhm.cm^2 at a collector current density of 100 A/cm^2 at room temperature. An the SiC IGBT showed a turn-of.

Non-isothermal simulation to predict heat dissipation and lattice temperature rise in a SiC device structure under switching condition has been explained in detail. Key pointers including runtime error messages, code debugging, implications of using certain models and parameter values, and other factors beneficial to device simulation are provided based on the authors' experience while simulating SiC device structures.

This book was released on 2017 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Carbide is a promising wide bandgap material and gradually becoming the first choice of semiconductor for high density and high efficiency power electronics in medium voltage range (500-1500V). SiC has also excellent thermal conductivity and the devices fabricated with the material can operate at high temperature ( ̃400 0C). Thus, a power electronic system built with SiC devices requires less cooling requirement and saves board space and cost. The high temperature applications of SiC material can also be extended to space exploration, oil and gas rigging, aerospace and geothermal energy systems for data acquisition, sensing and instrumentation and power conditioning and conversion. But the high temperature capability of SiC can only be utilized when the integrated circuits can be designed in SiC technology and high fidelity compact models of the semiconductor devices are a priori for reliable and high yielding integrated circuit design. The objective of this work is to develop industry standard compact models for SiC NMOS and PMOS devices. A widely used compact model used in silicon industry called BSIM3V3 is adopted as a foundation to build the model for SiC MOSFET. The models optimized with the built-in HSPICE BSIM3V3.3 were used for circuit design in one tape-out but BSIM3V3 was found to be inadequate to model all of the characteristics of SiC MOSFET due to the presence of interface trapped charge. In the second tape-out, the models for SiC NMOS and PMOS were optimized based on the built-in HSPICE BSIM4V6.5 and a number of functioning circuits which have been published in reputed journal and conference were designed based on the models. Although BSIM4 is an enhanced version of BSIM3V3, it also could not model a few deviant SiC MOSFET characteristics such as body effect, soft saturation etc. The new model developed for SiC NMOS and PMOS based on BSIM4V7.0 is called BSIM4SIC and can model the entire range of device characteristics of the devices. The BSIM4SIC models are validated with a wide range of measured data and verified using the models in the simulation of numerous circuits such as op-amp, comparator, linear regulator, reference and ADC/DAC.

This book was released on 2014 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Carbide (SiC) has received a special attention in the last decades thanks to its superior electrical, mechanical and chemical proprieties. SiC is mostly used for applications where Silicon is limited, becoming a proper material for both unipolar and bipolar power device able to work under high power, high frequency and high temperature conditions. Aside from the outstanding theoretical and practical advantages still to be proved in SiC devices, the need for more accurate models for the design and optimization of these devices, along with the development of integrated circuits (ICs) on SiC is indispensable for the further success of modern power electronics. The design and development of SiC ICs has become a necessity since the high temperature operation of ICs is expected to enable important improvements in aerospace, automotive, energy production and other industrial systems. Due to the last impressive progresses in the manufacturing of high quality SiC substrates, the possibility of developing ICs applications is now feasible. SiC unipolar transistors, such as JFETs and MESFETs show a promising potential for digital ICs operating at high temperature and in harsh environments. The reported ICs on SiC have been realized so far with either a small number of elements, or with a low integration density. Therefore, this work demonstrates that by means of our SiC MESFET technology, multi-stage digital ICs fabrication containing a large number of 4H-SiC devices is feasible, accomplishing some of the most important ICs requirements. The ultimate objective is the development of SiC digital building blocks by transferring the Si CMOS topologies, hence demonstrating that the ICs SiC technology can be an important competitor of the Si ICs technology especially in application fields in which high temperature, high switching speed and harsh environment operations are required. The study starts with the current normally-on SiC MESFET CNM complete analysis of an already fabricated MESFET. It continues with the modeling and fabrication of a new planar-MESFET structure together with new epitaxial resistors specially suited for high temperature and high integration density. A novel device isolation technique never used on SiC before is approached. A fabrication process flow with three metal levels fully compatible with the CMOS technology is defined. An exhaustive experimental characterization at room and high temperature (300oC) and Spice parameter extractions for both structures are performed. In order to design digital ICs on SiC with the previously developed devices, the current available topologies for normally-on transistors are discussed. The circuits design using Spice modeling, the process technology, the fabrication and the testing of the 4H-SiC MESFET elementary logic gates library at high temperature and high frequencies are performed. The MESFET logic gates behavior up to 300oC is analyzed. Finally, this library has allowed us implementing complex multi-stage logic circuits with three metal levels and a process flow fully compatible with a CMOS technology. This study demonstrates that the development of important SiC digital blocks by transferring CMOS topologies (such as Master Slave Data Flip-Flop and Data-Reset Flip-Flop) is successfully achieved. Hence, demonstrating that our 4H-SiC MESFET technology enables the fabrication of mixed signal ICs capable to operate at high temperature (300oC) and high frequencies (300kHz). We consider this study an important step ahead regarding the future ICs developments on SiC. Finally, experimental irradiations were performed on W-Schotthy diodes and mesa-MESFET devices (with the same Schottky gate than the planar SiC MESFET) in order to study their radiation hardness stability. The good radiation endurance of SiC Schottky-gate devices is proven. It is expected that the new developed devices with the same W-Schottky gate, to have a similar behavior in radiation rich environments.
