This third edition has been extended considerably to incorporate more information on instrument influences on the interpretation of X-ray scattering profiles and reciprocal space maps. Another significant inclusion is on the scattering from powder samples, covering a new theoretical approach that explains features that conventional theory cannot. The new edition includes some of the latest methodologies and theoretical treatments, including the latest thinking on dynamical theory and diffuse scattering. Recent advances in detectors also present new opportunities for rapid data collection and some very different approaches in data collection techniques; the possibilities associated with these advances will be included. This edition should be of interest to those who use X-ray scattering to understand more about their samples, so that they can make a better judgment of the parameter and confidence levels in their analyses, and how the combination of instrument, sample and detection should be considered as a whole to ensure this.

X-ray scattering is used extensively to provide detailed structural information about materials. Semiconductors have benefited from X-ray scattering techniques as an essential feedback method for crystal growth, including compositional and thickness determination of thin layers. The methods have been developed to reveal very detailed structural information concerning material quality, interface structure, relaxation, defects, surface damage, and more.

During the last 20 years interest in high-resolution x-ray diffractometry and reflectivity has grown as a result of the development of the semiconductor industry and the increasing interest in material research of thin layers of magnetic, organic, and other materials. For example, optoelectronics requires a subsequent epitaxy of thin layers of different semiconductor materials. Here, the individuallayer thicknesses are scaled down to a few atomic layers in order to exploit quantum effects. For reasons of electronic and optical confinement, these thin layers are embedded within much thicker cladding layers or stacks of multilayers of slightly different chemical composition. It is evident that the interface quality of those quantum weHs is quite important for the function of devices. Thin metallic layers often show magnetic properties which do not ap pear for thick layers or in bulk material. The investigation of the mutual interaction of magnetic and non-magnetic layers leads to the discovery of colossal magnetoresistance, for example. This property is strongly related to the thickness and interface roughness of covered layers.

This book presents a practical guide to the analysis of materials and includes a thorough description of the underlying theories and instrumental aberrations caused by real experiments. The main emphasis concerns the analysis of thin films and multilayers, primarily semiconductors, although the techniques are very general. Semiconductors can be very perfect composite crystals and therefore their study can lead to the largest volume of information, since X-ray scattering can assess the deviation from perfection.The description is intentionally conceptual so that the reader can grasp the real processes involved. In this way the analysis becomes significantly easier, making the reader aware of misleading artifacts and assisting in the determination of a more complete and reliable analysis. The theory of scattering is very important and is covered in such a way that the assumptions are clear. Greatest emphasis is placed on the dynamical diffraction theory including new developments extending its applicability to reciprocal space mapping and modelling samples with relaxed and distorted interfaces.A practical guide to the measurement of diffraction patterns, including the smearing effects introduced to the measurement, is also presented.

Semiconductors have benefited from X-ray scattering techniques as an essential feedback method for crystal growth, including compositional and thickness determination of thin layers. The methods have been developed to reveal very detailed structural information concerning material quality, interface structure, relaxation, defects, surface damage, etc.This book provides a thorough description of the techniques involved in obtaining that information, including X-ray diffractometers and their associated instrument functions, data collection methods, and the simulation of the diffraction patterns observed. Also presented are examples and procedures for interpreting the data to build a picture of the sample, much of which will be common to materials other than semiconductors./a

The scales involved in modern semiconductor manufacturing and microelectronics continue to plunge downward. Effective and accurate characterization of materials with thicknesses below a few nanometers can be achieved using x-rays. While many books are available on the theory behind x-ray metrology (XRM), X-Ray Metrology in Semiconductor Manufacturing is the first book to focus on the practical aspects of the technology and its application in device fabrication and solving new materials problems. Following a general overview of the field, the first section of the book is organized by application and outlines the techniques that are best suited to each. The next section delves into the techniques and theory behind the applications, such as specular x-ray reflectivity, diffraction imaging, and defect mapping. Finally, the third section provides technological details of each technique, answering questions commonly encountered in practice. The authors supply real examples from the semiconductor and magnetic recording industries as well as more than 150 clearly drawn figures to illustrate the discussion. They also summarize the principles and key information about each method with inset boxes found throughout the text. Written by world leaders in the field, X-Ray Metrology in Semiconductor Manufacturing provides real solutions with a focus on accuracy, repeatability, and throughput.

With contributions by Paul F. Fewster and Christoph Genzel While X-ray diffraction investigation of powders and polycrystalline matter was at the forefront of materials science in the 1960s and 70s, high-tech applications at the beginning of the 21st century are driven by the materials science of thin films. Very much an interdisciplinary field, chemists, biochemists, materials scientists, physicists and engineers all have a common interest in thin films and their manifold uses and applications. Grain size, porosity, density, preferred orientation and other properties are important to know: whether thin films fulfill their intended function depends crucially on their structure and morphology once a chemical composition has been chosen. Although their backgrounds differ greatly, all the involved specialists a profound understanding of how structural properties may be determined in order to perform their respective tasks in search of new and modern materials, coatings and functions. The author undertakes this in-depth introduction to the field of thin film X-ray characterization in a clear and precise manner.

This volume collects the proceedings of the 23rd International Course of Crystallography, entitled "X-ray and Neutron Dynamical Diffraction, Theory and Applications," which took place in the fascinating setting of Erice in Sicily, Italy. It was run as a NATO Advanced Studies Institute with A. Authier (France) and S. Lagomarsino (Italy) as codirectors, and L. Riva di Sanseverino and P. Spadon (Italy) as local organizers, R. Colella (USA) and B. K. Tanner (UK) being the two other members of the organizing committee. It was attended by about one hundred participants from twenty four different countries. Two basic theories may be used to describe the diffraction of radiation by crystalline matter. The first one, the so-called geometrical, or kinematical theory, is approximate and is applicable to small, highly imperfect crystals. It is used for the determination of crystal structures and describes the diffraction of powders and polycrystalline materials. The other one, the so-called dynamical theory, is applicable to perfect or nearly perfect crystals. For that reason, dynamical diffraction of X-rays and neutrons constitutes the theoretical basis of a great variety of applications such as: • the techniques used for the characterization of nearly perfect high technology materials, semiconductors, piezoelectric, electrooptic, ferroelectric, magnetic crystals, • the X-ray optical devices used in all modem applications of Synchrotron Radiation (EXAFS, High Resolution X-ray Diffractometry, magnetic and nuclear resonant scattering, topography, etc. ), and • X-ray and neutron interferometry.
