Particles On Surfaces

This volume chronicles the proceedings of the Symposium on Particles on Surfaces: Detection, Adhesion and Removal held under the auspices of the Fine Particle Society in San Francisco, July 28-August 2, 1986. The study of particles on surfaces is extremely important in many areas of human endeavor (ranging from microelectronics to optics to biomedical). A complete catalog of modern precision and sophisticated technologies where particles on surfaces are of cardinal importance will be prohibitively long, but the following eclectic examples should underscore the concern about particles on a variety of surfaces. In the semiconductor world of shrinking dimensions, particles which, a few years ago, were cosmetically undesirable but functionally innocuous can potentially be killer defects now. As the device sizes get smaller, there will be more and more concern about smaller and smaller particles. In the information storage technology, the gap between the head and the disk is very narrow, and if a particle is trapped in the gap that can have very grave consequences. The implications of particulate contamination on sensitive optical surfaces is all too manifest. So the particulate contamination on surfaces is undesirable from functional, yield and reliability points of view. This symposium was organized with the following objectives in mind: to bring together active practitioners in this field; to provide a forum for discussion of the latest research and development activities in this area; to provide opportunity for cross-pollination of ideas; and to highlight topics which needed intensified effort.

This work comprises the proceedings of the Fourth Symposium on Particles on Surfaces. Papers cover: adhesion-induced deformations of particles on surfaces; the use of atomic force microscopy in probing particle-particle adhesion; particle contamination in microelectronics, on spacecraft, and on optical surfaces; the role of air ionization in reducing surface contamination by particles in the cleanroom; abrasive blasting media for contamination-free deburring processes; and more.;The book is intended for physical, chemical, surface and colloid chemists, materials scientists; polymers, plastics, electrical and electronics, computer, chemical and mechanical engineers; and upper-level undergraduate and graduate students in these disciplines.

This volume chronicles the proceedings of the Third Symposium on Particles on Surfaces : Detection, Adhesion and Removal held as a part of the 21st Annual Meeting of the Fine Particle Society in San Diego , California, August 21 - 25 , 1990 . The first two symposia i n t h i s series were held in 1986 and 1988 , respectively, and have been properly l documented ,2. Li ke its antecedent s the Third symposium was very well received, and the continuing success of these symposia reinforced our earlier belief that regular symposia on the topic of particles on surfaces were very much needed. Concomitantly, the fourth symposium in this series is planned in Las Vegas , July 13-17 , 199 2 . l As pointed out in the Preface to the earlier two volumes ,2, the topic of particles on surfaces is of tremendous interest and concern in a wide spectrum of technological areas . The objectives of the Third symposium were es s ent i a l ly the same as those of the earlier two and our intent her e was to provide an update on the research and development activities in the world of particles on surfaces . Apropos , there has been a deliberate attempt every time to s eek out new people to present their research results and we have been very succes s f ul in this mission.

This volume documents the proceedings of the Second Symposium on Particles on Surfaces: Detection, Adhesion and Removal held as part of the 19th Annual Meeting of the Fine Particle Society in Santa Clara, California, July 20-25, 1988. The premier symposium on this topic was l organized in 1986 and has been properly chronicled . Based on the success of these two events and the high interest evinced by the technical community, we plan to regularly hold symposia on this topic on a biennial basis and the next one is slated for August 20-24, 1990 in San Diego, California. l As pointed out in the Preface to the first volume , the topic of particles on surfaces is of paramount importance in legion of technological areas. Particularly in the semiconductor device fabrication area, all signals indicate that the understanding of the behavior of particles on surfaces and their removal will attain heightened importance in the times to come. As the device dimensions are shrinking at an accelerated pace, so the benign particles of today will become the killer defects in the not too distant future. The tempo of research and development activity in the field of particles on surfaces is very high, and better and novel ways are continuously being devised to remove smaller and smaller particles.

This volume chronicles the proceedings of the 9th International Symposium on Particles on Surfaces: Detection, Adhesion and Removal held in Philadelphia, PA, June 2004. The study of particles on surfaces is crucially important in a legion of diverse technological areas, ranging from microelectronics to biomedical to space. This volume contains a to

This volume documents the proceedings of the 7th International Symposium on Particles on Surfaces: Detection, Adhesion and Removal held in Newark, NJ, June 19-21, 2000. The study of particles on surfaces is extremely important in a host of diverse technological areas, ranging from microelectronics to optics to biomedical. This volume contains a total of 28 papers, which were all properly peer reviewed, revised and edited before inclusion. Therefore, this book is not merely a collection of unreviewed manuscripts, but rather represents information which has passed peer scrutiny. Furthermore, the authors were asked to update their manuscripts, so the information contained in this book should be current and fresh. This volume is divided into two parts: 1) Particle Analysis and General Cleaning-Related Topics; and 2) Particle Adhesion and Removal. The topics covered include: surface analysis techniques for particle identification; cleaning, rinsing and drying issues in post-CMP cleaning; fundamental forces involved in particle adhesion; factors affecting adhesion of small (nanosize) particles; factors important in particle detachment; particle adhesion measurement by AFM; various (wet and dry) techniques for particle removal, e.g., laser, ultrasonic, megasonic, use of surfactants; toner particles and pharmaceutical particles. This volume offers a wealth of information on the tremendously technologically important field of particles on surfaces and should provide a consolidated source of current R&D activity in this arena. Therefore, it will be of value and use to anyone interested in the topic of particles on surfaces.
