Available in PDF, EPUB and Kindle. Book excerpt: A novel metallization for aluminum nitride substrates to package silicon carbide integrated circuits for use at temperatures of 600 deg C and above was investigated. Chemical equilibrium calculations were used to determine the chemical compatibility of several refractory and transition metal disilicides with AlN and SiC. Tungsten disilicide, niobium disilicide, and titanium disilicide were selected for diffusion couple and thin film deposition studies. AlN-WSi2-SiC, AlN-NbSi2-SiC, and AlN-TiSi2-SiC diffusion couples were formed at 1000 deg C and 1200 deg C. WSi2, NbSi2, and TiSi2 thin films were deposited by RF sputtering on AIN substrates and heat treated at 900 deg C, 1000 deg C, and l200 deg C in an argon atmosphere, while WSi2 thin film was deposited on a single crystal SiC wafer and heat treated at 900 deg C. Sheet resistivities were measured, and interfaces were characterized by scanning and transmission electron microscopy imaging, electron diffraction, and energy dispersive x ray microanalysis spectroscopy. The results show that metal silicides appear to be promising as metallization for aluminum nitride for use at 600 deg C and above.

Available in PDF, EPUB and Kindle. Book excerpt: A novel metallization for aluminum nitride substrates and related interconnection materials were investigated for packaging silicon carbide devices for use at temperatures up to 600 deg C. Aluminum nitride substrates were metallized with refractory metals using both thin and thick film metallization techniques. Excellent metallization adhesions (>- 10 ksi) were achieved at low sheet resistivities for both films. Phase diagrams were used to select potential bond pad, die attach and wire bond materials. Diffusion couples were constructed to screen the selected candidates. Gold and platinum were found to be stable bond pad materials on the refractory metallizations at 700 deg C. Gold-gold and platinum-platinum pad-wire combinations were suitable for use at temperatures of 600 deg C and beyond. Platinum-gold, copper-gold, and nickel-gold pad-wire combinations could be used with refractory metallized aluminum nitride substrate up to 400 deg C.

Download or read book High Temperature Electronics written by F. Patrick McCluskey and published by CRC Press. This book was released on 2018-05-04 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of electronics that can operate at high temperatures has been identified as a critical technology for the next century. Increasingly, engineers will be called upon to design avionics, automotive, and geophysical electronic systems requiring components and packaging reliable to 200 °C and beyond. Until now, however, they have had no single resource on high temperature electronics to assist them. Such a resource is critically needed, since the design and manufacture of electronic components have now made it possible to design electronic systems that will operate reliably above the traditional temperature limit of 125 °C. However, successful system development efforts hinge on a firm understanding of the fundamentals of semiconductor physics and device processing, materials selection, package design, and thermal management, together with a knowledge of the intended application environments. High Temperature Electronics brings together this essential information and presents it for the first time in a unified way. Packaging and device engineers and technologists will find this book required reading for its coverage of the techniques and tradeoffs involved in materials selection, design, and thermal management and for its presentation of best design practices using actual fielded systems as examples. In addition, professors and students will find this book suitable for graduate-level courses because of its detailed level of explanation and its coverage of fundamental scientific concepts. Experts from the field of high temperature electronics have contributed to nine chapters covering topics ranging from semiconductor device selection to testing and final assembly.
