This book was released on 2004-08-24 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide (SiC) is a wide-bandgap semiconductor that can operate at temperatures well above 300ºC, where silicon cannot perform. In addition, due to a high thermal conductivity equal to copper at room temperature, SiC is an ideal candidate for operation in harsh environments and at high-power levels. Rapid advances in SiC materials and devices have recently resulted in implementation of SiC-based electronic systems, and the impact of these devices is expected to significantly increase in the next several years. This book documents the most recent results on growth of bulk and epitaxial layers, physical and structural properties, process technology, and device development obtained since the 10th International Conference on Silicon Carbide and Related Materials 2003 (ICSCRM2003) held in Lyon, France. Extended defects in silicon carbide are highlighted. The nature of defects induced by forward biasing of bipolar devices, as well as methods to suppress the degradation, are addressed.

Download or read book The Properties of SiC Barrier Diodes Fabricated with Ti Schottky Contacts written by Krishna Chaitanya Kundeti and published by . This book was released on 2017 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium (Ti) is a popular metal contact used in fabricating Schottky barrier diodes on silicon carbide (SiC) semiconductor. In this research, Ti/4H-SiC Schottky barrier diodes have been fabricated to investigate the effect of deposition temperature and annealing on the electrical characteristics of the fabricated devices. The parameters such as barrier height, ideality factor and on-resistance were determined from the current-voltage (I-V) and the capacitance-voltage (C-V) measurements at room temperature. The temperature-dependent electrical characteristics are realized by performing current-voltage-temperature (I-V-T) measurements. Furthermore, the material characterizations were performed using Auger Electron Spectroscopy (AES) and x-ray diffraction (XRD) measurements. Thin films of Titanium (Ti) as Schottky contacts were deposited on n-type 4H-SiC substrate by magnetron sputtering at different temperatures form room temperature ~25 °C to 900 °C. In addition, thermal processing was performed by annealing at 500 °C in vacuum and argon environment up to 60 hours and characterized using I-V, C-V, and I-V-T measurements accordingly. The diodes with Ti deposited at 200 °C yield better devices with an average ideality factor of 1.04 and Schottky barrier height of 1.13 eV. The electrical properties shows that the deposition of Schottky contact should be at least below 700 °C and the Schottky contact should be annealed at 500 °C for 12-36 hours in order to obtain acceptable quality of Schottky diode. We believe that these variations in the electrical properties are due to the change in the quality of interfacial layer. The variations in physical/compositional properties of Ti/SiC interface has been investigated using Auger electron spectroscopy and x-ray diffraction, which reveled mainly two kinds of phases: Ti5Si3 and Ti3SiC2 formed at the interfacial layer.
Download or read book Physics and Technology of Silicon Carbide Devices written by Yasuto Hijikata and published by BoD – Books on Demand. This book was released on 2012-10-16 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, some SiC power devices such as Schottky-barrier diodes (SBDs), metal-oxide-semiconductor field-effect-transistors (MOSFETs), junction FETs (JFETs), and their integrated modules have come onto the market. However, to stably supply them and reduce their cost, further improvements for material characterizations and those for device processing are still necessary. This book abundantly describes recent technologies on manufacturing, processing, characterization, modeling, and so on for SiC devices. In particular, for explanation of technologies, I was always careful to argue physics underlying the technologies as much as possible. If this book could be a little helpful to progress of SiC devices, it will be my unexpected happiness.

Available in PDF, EPUB and Kindle. Book excerpt: Current power electronics world require semiconductor devices which are capable of highly reliable performances under extreme conditions of voltages and temperature. Wide band gap semiconductors are more suitable in comparison to the traditional semiconductors in such cases. One such semiconductor currently in focus is SiC. This book describes the strucutral, electronic and magnetic properties of SiC. It presents the results of coputational studies of few intrinsic and extrinsic impurities in SiC and their combination too. Many conclusions are found which can throw some light on its practical usefulness. The impurities considered are, B, Al, Ga, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and W. We have used first principle density functional theory with different exchange and correlation schemes using pseudopotentials to perform the electronic structure calculations of several defects in SiC. The theoretical background for computation has also been described in this book.
