Available in PDF, EPUB and Kindle. Book excerpt: Chemical vapor deposited (CVD) diamond thin films grown homoepitaxially as well as on non-diamond substrates have been the subject of intense investigation since the beginning of the last decade. Diamond's remarkable properties such as physical hardness, chemical inertness, high thermal conductivity, high breakdown voltage, and high carrier mobility are the main factors for the attention it has received from many researchers around the world. Although these properties are somewhat degraded in polycrystalline diamond films, they are still superior to many other materials. One of the most potentially useful applications of diamond thin films is in the semiconductor industry. Although a few prototype devices such as field effect transistors and Schottky diodes have been fabricated on diamond, some major obstacles remain to be overcome before full scale commercial applications of diamond as a semiconductor is possible. The high cost of large area monocrystalline diamond substrates has forced researchers to look for alternative substrates for the heteroepitaxial growth of diamond. So far only marginal results have been reported on the growth of highly oriented diamond films and on the heteroepitaxial growth involving substrates that are as costly as diamond. Silicon, as the dominant material in semiconductor industry, has been the subject of much research as a substrate for the growth of polycrystalline diamond. Another problem in development of diamond as a semiconductor is the effective doping of diamond, particularly for n-type conductivity. Although many researchers have studied boron-doped (p-type) diamond thin films in the past several years, there have been few reports on the effects of doping diamond films with phosphorous (n-type). Once these two issues have been solved, other fabrication steps such as oxidation, etching, masking, etc. may be attempted. The present work is a study directed toward solving some of these problems by looking at in-situ doping of n-type hot filament CVD (HFCVD) grown diamond films on silicon substrates. The study includes electrical characterization, stable metallic contacts, effect of silicon substrate surface pretreatment, and selective area deposition. A number of different techniques for inducing diamond nucleation on Si substrates are studied and the resulting diamond films characterized by common techniques such as Raman spectroscopy, X-ray diffraction, optical and scanning electron microscopy, and profilometery. The effect of doping the diamond films with different concentrations of phosphorous as well as calculation of the activation energy by temperature measurement was also carried out in this work. A new technique is presented for the selective deposition of diamond films onto silicon substrates.

This book was released on 2004-08-08 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond, as well as being a precious gem, is a versatile material par excellence. No other material comes anywhere near to matching its properties, which are both extreme, and also expressed in rare combinations. However, natural diamonds, and those synthesised under high sandpressure temperatures, are too expensive or small for many technological applications. These limitations can be overcome by using large-area diamond coatings; chemically bonded to inexpensive non-diamond surfaces. The consequent economic advantages provide the driving force for much diamond-related research and technology.

This book was released on 2012-12-06 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond films grown by activated chemical vapor deposition have superlative thermal, mechanical, optical, and electronic properties combined with a very high degree of chemical inertness to most environments. These properties, together with the ability to fabricate films and shapes of considerable size, promise an exciting new material with many applications. Some applications are on the verge of commercialization but many await a few more technological developments. Diamond-like films are already employed in both commercial and military applications. The popular press, as well as the scientific and technological and industrial communities, are increasingly interested in the potential for future development of these materials. Although there are many technical papers and review articles published, there is no Single comprehensive introduction to these technologies. The Scientific Affairs Division of NATO recognized the need and the future importance of these technologies and authorized an Advanced Study Institute on diamond and diamond-like films. NATO Advanced Study Institutes are high level teaching activities at which a carefully defined subject is presented in a systematic and coherently structured program. The subject is treated in considerable depth by lecturers eminent in their fields and of international standing. The presentations are made to students who are scientists in the field or who possess an advanced general scientific background.

Book excerpt: - Discusses the most advanced techniques for diamond growth - Assists diamond researchers in deciding on the most suitable process conditions - Inspires readers to devise new CVD (chemical vapor deposition Ever since the early 1980s, and the discovery of the vapour growth methods of diamond film, heteroexpitaxial growth has become one of the most important and heavily discussed topics amongst the diamond research community. Kobashi has documented such discussions with a strong focus on how diamond films can be best utilised as an industrial material, working from the premise that crystal diamond films can be made by chemical vapour disposition. Kobashi provides information on the process and characterization technologies of oriented and heteroepitaxial growth of diamond films.

Available in PDF, EPUB and Kindle. Book excerpt: An intensifying interest from the scientific, technical, and industrial community in the new diamond technology can be attested to by the wide range of contributions in this proceedings volume. The papers discuss topics such as the applications of diamond films and related wide bandgap semiconductors and superhard materials. These materials are rapidly becoming economically significant due to their combination of superior properties: great hardness, high thermal conductivity, chemical inertness, high stiffness, high carrier mobilities, etc. Initial commercial products employing the new diamond technology are already on the market. These include diamond loudspeakers, diamond X-ray windows, diamond bonders, diamond cutting tools, and heads for magnetic disks coated with diamond-like carbon. The developments reported in this volume are important not only in terms of their own markets, but, also because they are expected to enable a wide range of other new products and production methods.

Available in PDF, EPUB and Kindle. Book excerpt: Scaleup of hot filament chemical vapor deposition of diamond films requires knowledge of how filament geometry affects the deposition process. The effect of multiple filament geometry on the growth rate and surface morphology of diamond films is presented. Three factors were varied: the number of helical turns in a filament - 5, 10 or 15; the number of filaments present --1 or 2; and the CH4 fraction in the CH4-H2 feed gas mixture -- 0.25%, 0.5%, 0.75% or 1.0%. Other depositions parameters were 750 C substrate temperature, 52 standard cm/m total feed gas flow rate, and 5300 Pa deposition pressure. The deposition chamber volume was 1.9 liters. Increasing the CH4 concentration in the feed gas results in higher growth rates. However, increasing the number of filament turns in dual filament systems resulted in lower than expected growth rates for dual 10 and 15 turn filaments.
