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.

This book was released on 2001 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion flame assisted CVD of diamond has been carried out on variety of substrates to examine the mechanism of nucleation and growth and the role of the interface in this process. Initial studies were carried out on native oxide covered Si (100), and Si (100) with thin thermal oxide films (100 nm, 200 nm). After pretreatment under reducing flame conditions, a SiC layer, identified by X-ray Photoelectron Spectroscopy, was produced on all three substrates. The SiC/SiO2 ratio varied systematically with deposition time. Atomic Force Microscopy (AFM) suggests SiC particles were randomly distributed over the substrates early in the nucleation phase. Pretreatments in the fuel rich flame induce SiC formation after an induction time dictated by the thickness of the oxide film. Following SiC formation, diamond crystals, detected by photoelectron spectroscopy and Micro-Raman spectroscopy, can be grown on all three substrates with similar growth rates. In a laser pyrolysis study, with the subsequent deposition of diamond films in mind, the laser powered decompositions of silacyclobutane (SCB). 1,3-disilacyclobutane (DSCB) have been investigated. By changing the deposition conditions and the mixing ratio of the precursors, amorphous silicon carbide CVD films (Si1-xCx) have been deposited as buffer layers for subsequent diamond film deposition. Atomic Force Microscopy (AFM) shows that the deposits consist of very uniform films. XPS shows the stoichiometry of the deposits obtained from SCB and DSCB are SiC2.4O0.3 and SiC1.1O0.2 respectively. The laser pyrolysis technique has the advantages of producing desirable and controllable Si/C stoichiometry at lower deposition temperatures than conventional CVD methods. However, the instability of the films on exposure to air makes the method unsuitable as a precursor to CA-CVD diamond deposition. In the last part of thesis, the role of carbide and oxy-carbide films in the adhesion of CA-CVD deposited diamond films on commercial pure Ti metal, and a Ti, 6%Al,4%V substrates was examined. It was found that the carbon to oxygen ratio in an oxy-carbide structure formed at the interface broadly correlates with the adhesive strength of the diamond/substrate bond. Deposition experiments suggest the nature of the substrate is important in aiding carbide and subsequently diamond formation. The formation of a stable carbide clearly assists in the nucleation phase and in enhancing bonding at the interface, but it is far from clear that it is an essential precursor to the formation of diamond. Rather it appears to act to stabilize the substrate surface while diamond growth is established. SIMS depth profiles also show that the interfacial surface on Ti-6Al-4V contains several percent of aluminium and nitrogen, both at the outermost surface and in the interior of the interfacial layer. The aluminum is enriched at the surface as compared with the bulk concentration, and diamond nucleation is accelerated on this surface relative to pure Ti- These experiments with CA-CVD diamond deposition confirm that despite the very different gas composition used in diamond deposition, the initial mechanisms of nucleation and growth are very similar to those observed in other CVD diamond growth technologies. The major difference is the much higher rate at which these steps occur. This has made it a significant challenge to examine the nature and role of the interface in these experiments. It is clear that this zone is critical in controlling adhesion and growth of diamond on the various substrates used.

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 1994-12-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of diamond for electronic applications is not a new idea. As early as the 1920's diamonds were considered for their use as photoconductive detectors. However limitations in size and control of properties naturally limited the use of diamond to a few specialty applications. With the development of diamond synthesis from the vapor phase has come a more serious interest in developing diamond-based electronic devices. A unique combination of extreme properties makes diamond partiCularly well suited for high speed, high power, and high temperature applications. Vapor phase deposition of diamond allows large area films to be deposited, whose properties can potentially be controlled. Since the process of diamond synthesis was first realized, great progress have been made in understanding the issues important for growing diamond and fabricating electronic devices. The quality of both intrinsic and doped diamond has improved greatly to the point that viable applications are being developed. Our understanding of the properties and limitations has also improved greatly. While a number of excellent references review the general properties of diamond, this volume summarizes the great deal of literature related only to electronic properties and applications of diamond. We concentrate only on diamond; related materials such as diamond-like carbon (DLC) and other wide bandgap semiconductors are not treated here. In the first chapter Profs. C. Y. Fong and B. M. Klein discuss the band structure of single-crystal diamond and its relation to electronic properties.
