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.

Available in PDF, EPUB and Kindle. Book excerpt: The turn-on characteristics of a SiC Schottky diode are analyzed theoretically, by simulation, and by experiment. The static characteristics of SiC Schottky diodes and Si junction diodes are analyzed for normal and high temperatures. The effects of diffusion capacitance and junction capacitance on the turn-off transition of SiC Schottky diode have been analyzed theoretically. The turn-off transition of a SiC Schottky barrier diode is analyzed by modeling the metal-semiconductor junction capacitance considering the linear and the non-linear effects. Behavior of the linear and the non-linear metal-semiconductor junction capacitance models are evaluated exper- imentally. The performance of SiC Schottky diodes is compared to the performance of similarly rated Si junction diodes. The effect of diode reverse-recovery current on the primary switch of a PFC boost converter is analyzed by the aid of PSPICE simulations. A 250 W, PFC boost con- verter is designed and simulated. In the 250 W PFC boost converter, the perfor- mance of SiC Schottky diode and similarly rated Si junction diodes are evaluated. The PSPICE simulation models of a SiC Schottky diode and two Si junction diodes are compared and some important parameters are discussed and their effect on the turn-off transition of the diodes are presented. The principle and advantages of polyphase operation of buck converters is ana- lyzed. The design equations for a two-phase buck converter operating in CCM are derived. A two-phase 6 V/120 W (PWM) buck converter is designed and simulated using PSPICE. The design equations are verified by PSPICE simulation results.

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.
