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 1997 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond's unique properties are potentially superior among the existing substrate materials for electronic applications. Among these properties, diamond's physical hardness, molar density, thermal conductivity, and sound velocity are the highest while its thermal expansion coefficient, compressibility, and bulk modules are the lowest. Because of this unique combination of properties, diamond has diverse applications in electronics, optics, and material coatings. Scientists around the world have been studying possible applications of diamond and its synthesis by chemical vapor deposition (CVD) in the semiconductor industry for almost the latter half of this century. The use of bulk crystals severely limits semiconductor applications of diamond due to difficulty in doping, device integration, high cost, and small area of bulk diamond. Therefore, a great deal of effort has been undertaken by researchers around the world on diamond synthesis by chemical vapor deposition (CVD). With some of the same limitations, homoepitaxial growth of diamond is not considered to be a feasible solution. As a result, heteroepitaxial growth of diamond is being considered to be an attractive possibility. Heteroepitaxial diamond growth has been the main subject of research since the first successful growth of diamond thin films on foreign substrates was reported. Polycrystalline and highly oriented diamond thin films grown on various substrates, especially silicon, have been reported over the years. There also have been reports of device fabrication on diamond such as diamond based point contact transistors, Schottky diodes, and field effect transistors at a laboratory level. The technology has been very challenging and there remain many obstacles to overcome before diamond based devices are to become part of the semiconductor industry. For example, epitaxial growth of CVD diamond, selective doping, n-type doping, and metallization of the grown films are not totally understood due to the polycrystalline nature of CVD diamond films. The objective of this work is the study of hot-filament chemical vapor deposited boron doped polycrystalline diamond thin films grown on both silicon and sapphire. A new horizontal gas flow configuration rather than the typical vertical gas flow configuration is utilized to provide larger area and better quality films grown on these substrates. The study includes characterization of grown films using scanning electron microscopy, Raman spectroscopy, X-ray diffraction analysis, and electrical characterization. Two types of contacts to the films grown on silicon substrates are fabricated enabling various electrical measurements. However, on sapphire substrates, low volume resistivity diamond films are grown despite severe adhesion problems. The effects of various substrate pre-treatments, growth conditions, and doping concentrations are presented.

This book was released on 1990-02-01 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent discoveries enabling the growth of crystalline diamond by chemical vapor deposition offer the potential for a wide variety of new applications. This new book examines the state of the technology arising from these discoveries in relation to other allied materials, such as high-pressure diamond and cubic boron nitride. Most of the potential defense, space, and commercial applications are related to diamond's hardness, but some utilize its other qualities, such as optical and electronic properties. The authors review growth processes and discuss techniques for characterizing the resulting materials' properties. Crystalline diamond is emphasized, but other diamond-like materials (e.g. silicon carbide and amorphous carbon containing hydrogen) are also examined. In addition, the authors identify scientific, technical, and economic problems that could impede the rapid exploitation of these materials, and present recommendations covering broad areas of research and development.
