This book was released on 2007 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determining the composition of thin layers is increasingly important for a variety of industrial materials such as adhesives, coatings and microelectronics. Secondary ion mass spectrometry (SIMS), Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), glow discharge optical emission spectroscopy (GDOES), glow discharge mass spectrometry (GDMS), and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) are some of the techniques that are currently employed for the direct analysis of the sample surface. Although these techniques do not suffer from the contamination problems that often plague sample dissolution studies, they do require matrix matched standards for quantification. Often, these standards are not readily available. Despite the costs of clean hoods, Teflon pipette tips and bottles, and pure acids, partial sample dissolution is the primary method used in the semiconductor industry to quantify surface impurities. Specifically, vapor phase decomposition (VPD) coupled to ICP-MS or total reflection x-ray fluorescence (TXRF) provides elemental information from the top most surface layers at detection sensitivities in the 107-101°atoms/cm2 range. The ability to quantify with standard solutions is a main advantage of these techniques. Li and Houk applied a VPD-like technique to steel. The signal ratio of trace element to matrix element was used for quantification. Although controlled dissolution concentrations determined for some of the dissolved elements agreed with the certified values, concentrations determined for refractory elements (Ti, Nb and Ta) were too low. LA-ICP-MS and scanning electron microscopy (SEM) measurements indicated that carbide grains distributed throughout the matrix were high in these refractory elements. These elements dissolved at a slower rate than the matrix element, Fe. If the analyte element is not removed at a rate similar to the matrix element a true representation of the sample layer cannot be realized. Specifically, the ratio of analyte signal to matrix element signal does not equal the actual ratio in the bulk sample. The objective of this work was to investigate the controlled dissolution of other materials, simpler than steel. Matrices of copper, high copper alloy and NIST C1100 brass were investigated but the matrix that showed the best agreement between measured and certified values was NIST 612 glass. Further studies were conducted to limit the amount of surface layers removed for the NIST 612 matrix.

Download or read book Semiconductor Materials Analysis and Fabrication Process Control written by G.M. Crean and published by Elsevier. This book was released on 2012-12-02 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing awareness that the successful implementation of novel material systems and technology steps in the fabrication of microelectronic and optoelectronic devices, is critically dependent on the understanding and control of the materials, the process steps and their interactions. The contributions in this volume demonstrate that characterisation and analysis techniques are an essential support mechanism for research in these fields. Current major research themes are reviewed both in the development and application of diagnostic techniques for advanced materials analysis and fabrication process control. Two distinct trends are elucidated: the emergence and evaluation of sophisticated in situ optical diagnostic techniques such as photoreflectance and spectroellipsometry and the industrial application of ultra-high sensitivity chemical analysis techniques for contamination monitoring. The volume will serve as a useful and timely overview of this increasingly important field.

Download or read book Lea s Chemistry of Cement and Concrete written by Peter Hewlett and published by Elsevier. This book was released on 2003-11-12 with total page 1087 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lea's Chemistry of Cement and Concrete deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in manufacture and use. As such it is addressed not only to the chemist and those concerned with the science and technology of silicate materials, but also to those interested in the use of concrete in building and civil engineering construction. Much attention is given to the suitability of materials, to the conditions under which concrete can excel and those where it may deteriorate and to the precautionary or remedial measures that can be adopted. First published in 1935, this is the fourth edition and the first to appear since the death of Sir Frederick Lea, the original author. Over the life of the first three editions, this book has become the authority on its subject. The fourth edition is edited by Professor Peter C. Hewlett, Director of the British Board of Agrement and visiting Industrial Professor in the Department of Civil Engineering at the University of Dundee. Professor Hewlett has brought together a distinguished body of international contributors to produce an edition which is a worthy successor to the previous editions.
