Book Description
This report results from a contract tasking Technion as follows: Investigate the characteristics of thin silicon nitride films deposited on substrates via the use of chemical laser deposition techniques. This report summarized the research activities during the first year of work as was planned in the proposal. It completes the information which was given in the previous two progress reports. Basically, the aim of the first year was to study the possibility of deposition of silicon nitride thin films from silane and ammonia at low temperatures. The investigation was carried out by studying the effect of substrate temperature on deposition rate and film quality. In addition, the photochemical reaction was studied by analyzing the composition of gas molecules prior and during laser irradiation. At the end of the first year it was also possible to start doing experiments for deposition of silicon carbide from silane and acetylene.

Book Description
Laser processing is now a rapidly increasing field with many real and potential applications in different areas of technology such as micromecha nics, metallurgy, integrated optics, and semiconductor device fabrication. The neces s ity for such soph i st i cated 1 i ght sources as 1 asers is based on the spatial coherence and the monochromaticity of laser light. The spatial coherence permits extreme focussing of the laser light resulting in the availability of high energy densities which can be used for strongly loca lized heat- and chemical-treatment of materials, with a resolution down to 1 ess than 1 lJIll. When us i ng pul sed or scanned cw-l asers, 1 oca 1 i zat i on in time is also possible. Additionally, the monochromaticity of laser light allows for control of the depth of heat treatment and/or selective, nonthermal bond breaking - within the surface of the material or within the molecules of the surrounding reactive atmosphere - simply by tuning the laser wavelength. These inherent advantages of laser light permit micromachining of materials (drilling, cutting, welding etc.) and also allow single-step controlled area processing of thin films and surfaces. Processes include structural transformation (removal of residual damage, grain growth in polycrystalline material, amorphization, surface hardening etc.), etching, doping, alloying, or deposition. In addition, laser processing is not 1 imited to planar substrates.

Book Description
An up-to-date collection of tutorial papers on the latest advances in the deposition and growth of thin films for micro and nano technologies. The emphasis is on fundamental aspects, principles and applications of deposition techniques used for the fabrication of micro and nano devices. The deposition of thin films is described, emphasising the gas phase and surface chemistry and its effects on the growth rates and properties of films. Gas-phase phenomena, surface chemistry, growth mechanisms and the modelling of deposition processes are thoroughly described and discussed to provide a clear understanding of the growth of thin films and microstructures via thermally activated, laser induced, photon assisted, ion beam assisted, and plasma enhanced vapour deposition processes. A handbook for engineers and scientists and an introduction for students of microelectronics.

Book Description
The explosive growth in the semiconductor industry has caused a rapid evolution of thin film materials that lend themselves to the fabrication of state-of-the-art semiconductor devices. Early in the 1960s an old research technique named chemical vapour phase deposition (CVD), which has several unique advantages, developed into the most widely used technique for thin film preparation in electronics technology. In the last 25 years, tremendous advances have been made in the science and technology of thin films prepared by means of CVD. This book presents in a single volume, an up-to-date overview of the important field of CVD processes which has never been completely reviewed previously. Contents: Part I. 1. Evolution of CVD Films. Introductory remarks. Short history of CVD thin films. II. Fundamentals. 2. Techniques of Preparing Thin Films. Electrolytic deposition techniques. Vacuum deposition techniques.

Book Description
The authoritative reference on catalytic chemical vapor deposition, written by the inventor of the technology. This comprehensive book covers a wide scope of Cat-CVD and related technologies from the fundamentals to the many applications, including the design of a Cat-CVD apparatus. Featuring contributions from four senior leaders in the field, including the father of catalytic chemical vapor deposition, it also introduces some of the techniques used in the observation of Cat-CVD related phenomena so that readers can understand the concepts of such techniques. Catalytic Chemical Vapor Deposition: Technology and Applications of Cat-CVD begins by reviewing the analytical tools for elucidating the chemical reactions in Cat-CVD, such as laser-induced fluorescence and deep ultra-violet absorption, and explains in detail the underlying physics and chemistry of the Cat-CVD technology. Subsequently it provides an overview of the synthesis and properties of Cat-CVD-prepared inorganic and organic thin films. The last parts of this unique book are devoted to the design and operation of Cat-CVD apparatuses and the applications. Provides coherent coverage of the fundamentals and applications of catalytic chemical vapor deposition (Cat-CVD) Assembles in one place the state of the art of this rapidly growing field, allowing new researchers to get an overview that is difficult to obtain solely from journal articles Presents comparisons of different Cat-CVD methods which are usually not found in research papers Bridges academic and industrial research, showing how CVD can be scaled up from the lab to large-scale industrial utilization in the high-tech industry.
