Proceedings of the 6h International Symposium on Ultra Clean Processing of Silicon Surfaces (UCPSS 2002), Held in Ostens, Belgium, September 2002

The issues addressed by the Sixth International Symposium on the Ultra Clean Processing of Silicon Surfaces included all aspects of ultra-clean Si-technology, cleaning and contamination control in both front-end-of-line (FEOL) and back-end-of-line (BEOL) processing. This covered studies of Si-surface chemistry and topography and its relationship to device performance and process yield, cleaning in relationship to new gate stacks, cleaning at the interconnect level, resist stripping and polymer removal, cleaning and contamination control of various new materials, wafer backside cleaning and cleaning following Chemical-Mechanical-Polishing (CMP). Judging from the large number of papers dealing with wet cleaning processes, it is clear that this is still the dominant cleaning technology at the moment. Various papers discussed simplified cleaning by the use of chelating additives, and single-wafer wet cleaning; which is expected to replace the more standard multi-step batch-type cleaning systems, in various applications, in the future. Several contributions dealt with new materials introduced into current process research and development: such as Cu, and especially (porous) low-k material, as well as high-k and metal gate stacks. Substantial progress had also been made in understanding the effects of megasonics, and in the area of cleaning following Chemical-Mechanical Polishing (CMP). Last, but not least, an encouraging number of contributions were presented on the relatively new topic of supercritical CO2 cleaning. Altogether, the 76 contributions presented at the symposium represent a timely and authoritative assessment of the state-of-the-art of this very interesting and essential field.

A totally new concept for clean surface processing of Si wafers is introduced in this book. Some fifty distinguished researchers and engineers from the leading Japanese semiconductor companies, such as NEC, Hitachi, Toshiba, Sony and Panasonic as well as from several universities reveal to us for the first time the secrets of these highly productive institutions. They describe the techniques and equipment necessary for the preparation of clean high-quality semiconductor surfaces as a first step in high-yield/high-quality device production. This book thus opens the door to the manufacturing of reliable nanoscale devices and will be extremely useful for every engineer, physicist and technician involved in the production of silicon semiconductor devices.

Developments in Surface Contamination and Cleaning: Methods for Surface Cleaning, Volume 9, part of the Developments in Surface Contamination and Cleaning series provide a state-of-the-art guide to the current knowledge on the behavior of film-type and particulate surface contaminants and their associated cleaning methods. This newest volume in the series discusses methods of surface cleaning of contaminants and the resources that are needed to deal with them. Taken as a whole, the series forms a unique reference for professionals and academics working in the area of surface contamination and cleaning. A strong theme running through the series is that of surface contamination and cleaning at the micro and nano scales. - Provides a comprehensive coverage of innovations in surface cleaning - Written by established experts in the surface cleaning field, presenting an authoritative resource - Contains a comprehensive review of the state-of-the-art, including case studies to enhance the learning process

As science pushes closer toward the atomic size scale, new challenges arise to slow the pace of the miniaturization that has transformed our society and fueled the information age. New technologies are necessary to surpass these obstacles and realize the tremendous growth predicted by Moore's law. Assembled from the works of pioneering researchers, Scientific Wet Process Technology for Innovative LSI/FPD Manufacturing presents new developments and technologies for producing the next generation of electronic circuits and displays. This book introduces radical-reaction-based semiconductor manufacturing technologies that overcome the limitations of the existing molecule-reaction-based technologies. It systematically details the procedures and underlying concepts involved in wet process technologies and applications. Following an introduction to semiconductor surface chemical electronics, expert contributors discuss the principles and technology of high-performance wet cleaning; etching technologies and processes; antistatic technology; wet vapor resist stripping technology; and process and safety technologies including waste reclamation, chemical composition control, and ultrapure water and liquid chemical supply systems and materials for fluctuation-free facilities. Currently, large production runs are needed to balance the costs of acquiring and tuning equipment for specialized operating conditions. Scientific Wet Process Technology for Innovative LSI/FPD Manufacturing explains the technologies and processes used to meet the demand for variety and low volumes that exists in today's digital electronics marketplace.

The second Edition of the Handbook of Silicon Wafer Cleaning Technology is intended to provide knowledge of wet, plasma, and other surface conditioning techniques used to manufacture integrated circuits. The integration of the clean processes into the device manufacturing flow will be presented with respect to other manufacturing steps such as thermal, implant, etching, and photolithography processes. The Handbook discusses both wet and plasma-based cleaning technologies that are used for removing contamination, particles, residue, and photoresist from wafer surfaces. Both the process and the equipment are covered. A review of the current cleaning technologies is included. Also, advanced cleaning technologies that are under investigation for next generation processing are covered; including supercritical fluid, laser, and cryoaerosol cleaning techniques. Additionally theoretical aspects of the cleaning technologies and how these processes affect the wafer is discussed such as device damage and surface roughening will be discussed. The analysis of the wafers surface is outlined. A discussion of the new materials and the changes required for the surface conditioning process used for manufacturing is also included. - Focused on silicon wafer cleaning techniques including wet, plasma, and other surface conditioning techniques used to manufacture integrated circuits - As this book covers the major technologies for removing contaminants, it is a reliable reference for anyone that manufactures integrated circuits, or supplies the semiconductor and microelectronics industries - Covers processes and equipment, as well as new materials and changes required for the surface conditioning process - Editors are two of the top names in the field and are both extensively published - Discusses next generation processing techniques including supercritical fluid, laser, and cryoaerosol
