EUV Lithography


Book Description

Editorial Review Dr. Bakshi has compiled a thorough, clear reference text covering the important fields of EUV lithography for high-volume manufacturing. This book has resulted from his many years of experience in EUVL development and from teaching this subject to future specialists. The book proceeds from an historical perspective of EUV lithography, through source technology, optics, projection system design, mask, resist, and patterning performance, to cost of ownership. Each section contains worked examples, a comprehensive review of challenges, and relevant citations for those who wish to further investigate the subject matter. Dr. Bakshi succeeds in presenting sometimes unfamiliar material in a very clear manner. This book is also valuable as a teaching tool. It has become an instant classic and far surpasses others in the EUVL field. --Dr. Akira Endo, Chief Development Manager, Gigaphoton Inc. Description Extreme ultraviolet lithography (EUVL) is the principal lithography technology aiming to manufacture computer chips beyond the current 193-nm-based optical lithography, and recent progress has been made on several fronts: EUV light sources, optics, optics metrology, contamination control, masks and mask handling, and resists. This comprehensive volume is comprised of contributions from the world's leading EUVL researchers and provides all of the critical information needed by practitioners and those wanting an introduction to the field. Interest in EUVL technology continues to increase, and this volume provides the foundation required for understanding and applying this exciting technology. About the editor of EUV Lithography Dr. Vivek Bakshi previously served as a senior member of the technical staff at SEMATECH; he is now president of EUV Litho, Inc., in Austin, Texas.

Principles of Lithography


Book Description

Lithography is a field in which advances proceed at a swift pace. This book was written to address several needs, and the revisions for the second edition were made with those original objectives in mind. Many new topics have been included in this text commensurate with the progress that has taken place during the past few years, and several subjects are discussed in more detail. This book is intended to serve as an introduction to the science of microlithography for people who are unfamiliar with the subject. Topics directly related to the tools used to manufacture integrated circuits are addressed in depth, including such topics as overlay, the stages of exposure, tools, and light sources. This text also contains numerous references for students who want to investigate particular topics in more detail, and they provide the experienced lithographer with lists of references by topic as well. It is expected that the reader of this book will have a foundation in basic physics and chemistry. No topics will require knowledge of mathematics beyond elementary calculus.







Materials and Processes for Next Generation Lithography


Book Description

As the requirements of the semiconductor industry have become more demanding in terms of resolution and speed it has been necessary to push photoresist materials far beyond the capabilities previously envisioned. Currently there is significant worldwide research effort in to so called Next Generation Lithography techniques such as EUV lithography and multibeam electron beam lithography. These developments in both the industrial and the academic lithography arenas have led to the proliferation of numerous novel approaches to resist chemistry and ingenious extensions of traditional photopolymers. Currently most texts in this area focus on either lithography with perhaps one or two chapters on resists, or on traditional resist materials with relatively little consideration of new approaches. This book therefore aims to bring together the worlds foremost resist development scientists from the various community to produce in one place a definitive description of the many approaches to lithography fabrication. - Assembles up-to-date information from the world's premier resist chemists and technique development lithographers on the properties and capabilities of the wide range of resist materials currently under investigation - Includes information on processing and metrology techniques - Brings together multiple approaches to litho pattern recording from academia and industry in one place




Efficient Extreme Ultra-Violet Mirror Design


Book Description

Extreme ultraviolet (EUV) lithography is a next generation platform with the potential to extend Moore's Law. The EUV mirror is a fundamental component of this system. Efficient Extreme Ultraviolet Mirror Design describes an approach to designing EUV mirrors with reduced computational time and memory requirements, providing a comprehensive grounding in the fundamentals of the EUV mirror and knowledge of the finite-difference time-domain (FDTD) method. The discussion is made timely by the opening of commercial avenues for the application of EUV as it begins to be implemented in the development of 5G, AI, edge computing, VR and the Internet of Things. This book explores the theory, function and fabrication of EUV mirrors, as well as the correlation between design by Fresnel's equations and design by photonic bands, and develops a rigorous and efficient FDTD method by applying these considerations to three simulation cases. Intended primarily for EUV industry professionals, Efficient Extreme Ultraviolet Mirror Design will be of particular use to researchers investigating large scale problems or near-field scattering problems in EUV lithography. It will serve as an excellent reference text for anyone working in or studying optical engineering, as well as a high-level introduction for researchers from other fields interested in photolithography and the FDTD method. Key Features Addresses knowledge of extreme ultraviolet (EUV) mirrors and EUV lithography. Establishes a relation between photonic bands and Fresnel's equation. Introduces the high reflectivity EUV mirror design rules. Applies numerical simulation for EUV mirror design. Details efficient finite-difference time-domain (FDTD) approach.

Fundamental Principles of Optical Lithography


Book Description

The fabrication of an integrated circuit requires a variety of physical and chemical processes to be performed on a semiconductor substrate. In general, these processes fall into three categories: film deposition, patterning, and semiconductor doping. Films of both conductors and insulators are used to connect and isolate transistors and their components. By creating structures of these various components millions of transistors can be built and wired together to form the complex circuitry of modern microelectronic devices. Fundamental to all of these processes is lithography, ie, the formation of three-dimensional relief images on the substrate for subsequent transfer of the pattern to the substrate. This book presents a complete theoretical and practical treatment of the topic of lithography for both students and researchers. It comprises ten detailed chapters plus three appendices with problems provided at the end of each chapter. Additional Information: Visiting http://www.lithoguru.com/textbook/index.html enhances the reader's understanding as the website supplies information on how you can download a free laboratory manual, Optical Lithography Modelling with MATLABĀ®, to accompany the textbook. You can also contact the author and find help for instructors.
