Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Materials processing with lasers is a rapidly expanding field which is increasingly captivating the attention of scientists, engineers and manufacturers alike. The aspect of most interest to scientists is provided by the basic interaction mechanisms between the intense light of a laser and materials exposed to a chemically reactive or nonreactive surrounding medium. Engineers and manufacturers see in the laser a new tool which will not only make manufacturing cheaper, faster, cleaner and more accurate but which also opens up entirely new technologies and manufacturing methods that are simply not available using existing techniques. Actual and potential applications range from laser machining to laser-induced materials transformation, coating, patterning, etc. , opening up the prospect of exciting new processing methods for micromechanics, metallurgy, integrated optics, semiconductor manufacture and chemical engineering. This book concentrates on the new and interdisciplinary field of 1 aser-i nduced chemicaZ process i ng of materi als. The techni que permits maskless single-step deposition of thin films of metals, semiconductors or insulators with lateral dimensions ranging from a few tenths of a micrometer up to several centimeters. Moreover, materials removal or synthesis, or surface modifications, such as oxidation, nitridation, reduction, metallization and doping, are also possible within similar dimensions. This book is meant as an introduction. It attempts to cater for the very broad range of specific interests which different groups of readers will have, and this thinking underlies the way in which the material has been arranged.

Download or read book Reduced Thermal Processing for ULSI written by R.A. Levy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: As feature dimensions of integrated circuits shrink, the associated geometrical constraints on junction depth impose severe restrictions on the thermal budget for processing such devices. Furthermore, due to the relatively low melting point of the first aluminum metallization level, such restrictions extend to the fabrication of multilevel structures that are now essential in increasing packing density of interconnect lines. The fabrication of ultra large scale integrated (ULSI) devices under thermal budget restrictions requires the reassessment of existing and the development of new microelectronic materials and processes. This book addresses three broad but interrelated areas. The first area focuses on the subject of rapid thermal processing (RTP), a technology that allows minimization of processing time while relaxing the constraints on high temperature. Initially developed to limit dopant redistribution, current applications of RTP are shown here to encompass annealing, oxidation, nitridation, silicidation, glass reflow, and contact sintering. In a second but complementary area, advances in equipment design and performance of rapid thermal processing equipment are presented in conjunction with associated issues of temperature measurement and control. Defect mechanisms are assessed together with the resulting properties of rapidly deposited and processed films. The concept of RTP integration for a full CMOS device process is also examined together with its impact on device characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: Using lasers to induce and probe surface processes has the advantages of quantum state specificity, species selectivity, surface sensitivity, fast time-resolution, high frequency resolution, and accessibility to full pressure ranges. These advantages make it highly desirable to use light to induce, control, or monitor surface chemical and physical processes. Recent applications of laser based techniques in studying surface processes have stimulated new developments and enabled the understanding of fundamental problems in energy transfer and reactions. This volume will include discussions on spectroscopic techniques, energy transfer, desorption dynamics, and photochemistry.

This book was released on 2012-12-06 with total page 835 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the Proceedings of the November 8-10, 1982 Conference on EMERGENT PROCESS METHODS FOR HIGH TECHNOLOGY CERAMICS, held at North Carolina State University in Raleigh. It was the nineteenth in a series of "University Conferences on Ceramic Sci ence" initiated in 1964 by four institutions of which North Carolina State University is a charter member, along with the University of California at Berkeley, Notre Dame University, and the New York State College of Ceramics at Alfred University. More recently, ceramic oriented faculty in departments at the Pennsylvania State University and Case-Western Reserve University have joined the four initial institutions as permanent members of the consortium. These research oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both international and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference addressed the fundamental scientific background as well as the technological state-of-the-art of several novel methods which are beginning to influence present and future directions for non-traditional ceramic processing, thus affecting many of the advanced ceramic materials needed for a wide variety of research and industrial applications. The number, the importance and the application of new ceramic processing techniques have expanded considerably during the last ten years.
