Available in PDF, EPUB and Kindle. Book excerpt: Silicon (Si) is by far the most widely used semiconductor material for power devices. On the other hand, Si-based power devices are approaching their material limits, which has provoked a lot of efforts to find alternatives to Si-based power devices for better performance. With the rapid innovations and developments in the semiconductor industry, Silicon Carbide (SiC) power devices have progressed from immature prototypes in laboratories to a viable alternative to Si-based power devices in high-efficiency and high-power density applications. SiC devices have numerous persuasive advantages--high-breakdown voltage, high-operating electric field, high-operating temperature, high-switching frequency and low losses. Silicon Carbide (SiC) devices belong to the so-called wide band gap semiconductor group, which offers a number of attractive characteristics for high voltage power semiconductors when compared to commonly used silicon (Si). Recently, some SiC power devices, for example, Schottky-barrier diodes (SBDs), metal-oxide-semiconductor field-effecttransistors (MOSFETs), junction FETs (JFETs), and their integrated modules have come onto the market. Physics and Technology of Silicon Carbide Devices abundantly describes recent technologies on manufacturing, processing, characterization, modeling, etc. for SiC devices.

This book was released on 2012 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficiency of power management circuits depends significantly on their constituent switches and rectifiers. The demands of technology are increasingly running up against the intrinsic properties of Si based power devices. 4H-Silicon Carbide (SiC) has superior properties that make it attractive for high power applications. SiC rectifiers are already a competitive choice and SiC switches have also been commercialized recently. Junction Barrier Schottky (JBS) diodes, which combine the advantages of PN and Schottky, have higher Figure of Merit (FOM) as rectifiers. Among switches, a robust and mature process has been developed for Silicon Carbide Vertical Junction Field Effect Transistors (VJFETs), which currently gives it the highest unipolar FOM. Switches are frequently combined with anti-parallel diodes in power circuits. This thesis describes the development of a SiC-based monolithically integrated power switch and diode. Monolithic integration increases reliability and efficiency, and reduces cost. Because of their superior properties and similarities in fabrication, we chose the SiC VJFET and JBS diode as the switch and rectifier. Detailed design, fabrication and characterization of the integrated switch to block above 800 V and conduct current beyond 100 A/cm2 is explained. In this process, the first physics-based 2-D compact model is developed for reverse leakage in a JBS diode as a function of design parameters. Since the gate-channel junctions of SiC VJFETs cannot be assumed to be abrupt, an existing analytical model for Si VJFETs is extended to account for graded gate-channel junctions. Using these analytical models, design rules are developed for the VJFET and JBS diode. Finite element simulations are used to find the best anode layout of the JBS diode and optimize electric field termination in the integrated device to ensure their capability to operate at high voltage. Finally, a spin-on glass based process is developed for filling the gate trenches of the VJFET to improve long-term robustness in extreme environments. The integrated power switch developed in this thesis points to the attractions of monolithic integration in SiC power circuits. Analytical compact design equations derived here will facilitate faster and easier design of switches and rectifiers for desired circuit operation.

Available in PDF, EPUB and Kindle. Book excerpt: 4H-Silicon Carbide (4H-SiC) is a promising semiconductor for the next generation of high power, high frequency, and high temperature applications. Significant progresses have been made on SiC technologies since 1990's. Superior device performance demonstrated by SiC discrete power devices is leading to the commercialization of SiC diodes and transistors targeting mid and high power level applications. As compared to the vertical power devices, the lateral device technology promises to fulfill the monolithic integration of both power devices and control circuits. SiC power integrated circuits (PICs) share similar advantages as Si PICs while providing a much higher power handling capability at higher frequency. In addition, SiC power junction field transistor (JFET) is promising for high temperature, reliable operation without suffering from the reliability problems faced by metal-oxide-semiconductor junction field transistors (MOSFETs) and bipolar junction transistors (BJTs). Therefore, the lateral JFET technology is investigated under this research. This thesis describes design, fabrication, characterization, and further optimization and analysis of a novel vertical channel lateral JFET (VC-LJFET) technology in 4H-SiC and the demonstration of the world's first SiC power Integrated circuit. A double reduced surface electric field (RESURF) structure is applied to achieve higher voltage and lower on-resistance for the power lateral JFET (LJFET). A 4-stage buffer circuit based on the resistive-load n-type JFET inverter is designed and integrated with the power LJFET to form a monolithic power integrated circuit. Important fabrication procedures are presented. The fabricated power LJFET demonstrates a blocking voltage of 1028 V and a specific on-resistance of 9.1 m[ohm]; cm2, resulting in a record-high VBR2/RON, SP figure-of-merit (FOM) of 116 MW/cm2 for lateral power devices. The optimized RESURF structure demonstrates blocking capability of 120 V/[micro]m in 4H-SiC. The temperature dependences of important device parameters, such as threshold voltage, transconductance, and electron mobility, are also discussed. Based on the technology, the integration of a high performance lateral power JFET with buffer circuits has been demonstrated for the first time. The SiC LJFET power IC chips demonstrate a record high power level at frequencies up to a few MHz. An on-chip temperature sensing diode is implemented to monitor the chip junction temperature. The rise time and fall time around 20 ns for the SiC power LJFET are observed and remains unchanged even at a junction temperature as high as 250 oC when driven by a Si MOS gate driver. The demonstration of SiC power integration technology points to the robust integrated power electronics applications in the harsh environment and boosts the power level of single-chip power electronic system from 100 W to 1000 W.
