This book was released on 2013-03-14 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large amount of literature on the technology of thin film silicon nitride indi cates the interest of the Department of Defense, NASA and the semiconductor industry in the development and full utilization of the material. This survey is concerned only with the thin film characteristics and properties of silicon nitride as currently utilized by the semiconductor or microelectronics industry. It also includes the various methods of preparation. Applications in microelectronic devices and circuits are to be provided in Part 2 of the survey. Some bulk silicon nitride property data is included for basic reference and comparison purposes. The survey specifically excludes references and information not within the public domain. ACKNOWLEDGEMENT This survey was generated under U.S. Air Force Contract F33615-70-C-1348, with Mr. B.R. Emrich (MAAM) Air Force Materials Laboratory, Wright-Patterson Air Force Base, Ohio acting as Project Engineer. The author would like to acknowledge the assis tance of Dr. Judd Q.

This book was released on 2018-07-25 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a four year program to improve the strength and reliability of injection-molded silicon nitride are summarized. Statistically designed processing experiments were performed to identify and optimize critical processing parameters and compositions. Process improvements were monitored by strength testing at room and elevated temperatures, and microstructural characterization by optical, scanning electron microscopes, and scanning transmission electron microscope. Processing modifications resulted in a 20 percent strength and 72 percent Weibull slope improvement of the baseline material. Additional sintering aids screening and optimization experiments succeeded in developing a new composition (GN-10) capable of 581.2 MPa at 1399 C. A SiC whisker toughened composite using this material as a matrix achieved a room temperature toughness of 6.9 MPa m(exp .5) by the Chevron notched bar technique. Exploratory experiments were conducted on injection molding of turbocharger rotors. Yeh, Harry C. and Fang, Ho T.

Download or read book Fabrication of Heat Resistant and Plastic Formable Silicon Nitride written by Toshiyuki Nishimura and published by Springer. This book was released on 2015-07-23 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, improvements in the heat resistance of silicon nitride (Si3N4) ceramics using grain boundary control and in plasticity at high temperatures using grain size control in order to reduce the cost of shaping Si3N4 are described. The heat resistance of Si3N4 is improved by mixing a slight amount of sintering additive as an impurity into the original material powder. The author presents his findings on the high heat resistance of Si3N4. The author also develops a new fabrication method for Si3N4 nano-ceramics that produces high plastic formability. The method developed offers two improved points in grinding and sintering processes. The author found that the plastic formability of Si3N4 nanoceramics is dependent on load stress; the results of his research are detailed in this book.

Book excerpt: This survey is concerned with the use of silicon nitride in the semi conductor and microelectronics industries. The Handbook of Electronic Materials, volume 3, comprises part 1 of this survey and includes preparation and properties information. This report was prepared by Hughes Aircraft Company, Culver City, California under Contract Number F336lS-70-C-1348. The work was admini stered under the direction of the Air Force Materials Laboratory, Air Force Systems Command, Wright-Patterson Air Force Base, Ohio, with Hr. B. Emrich, Project Engineer. The Electronic Properties Information Center (EPIC) is a designated Information Analysis Center of the Department of Defense, authorized to pro vide information to the entire DoD community. The purpose of the Center is to provide a highly competent source of information and data on the electronic, optical and magnetic properties of materials of value to the Department of Defense. Its major function is to evaluate, compile and publish the experi mental data from the world's unclassified literature concerned with the properties of materials. All materials relevant to the field of electronics are within the scope of EPIC: insulators, semiconductors, metals, super conductors, ferrites, ferroelectrics, ferromagnetics, electroluminescents, thermionic emitters and optical materials. The Center's scope includes information on over 100 basic properties of materials; information generally regarded as being in the area of devices and/or circuitry is excluded. v CONTENTS Foreword. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . v Introduction. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Diffusion Mask Applications . . . . . . . . . . . . . . . . . . . . . . . . . . .
