The content is designed as a practical guide for engineers working at chip makers, equipment suppliers and materials suppliers, and university students studying plasma, focusing on the topics they need most, such as detailed etching processes for each material (Si, SiO2, Metal etc) used in semiconductor devices, etching equipment used in manufacturing fabs, explanation of why a particular plasma source and gas chemistry are used for the etching of each material, and how to develop etching processes. The latest, key technologies are also described, such as 3D IC Etching, Dual Damascene Etching, Low-k Etching, Hi-k/Metal Gate Etching, FinFET Etching, Double Patterning etc.

Learn about fundamental and advanced topics in etching with this practical guide Atomic Layer Processing: Semiconductor Dry Etching Technology delivers a hands-on, one-stop resource for understanding etching technologies and their applications. The distinguished scientist, executive, and author offers readers in-depth information on the various etching technologies used in the semiconductor industry, including thermal, isotropic atomic layer, radical, ion-assisted, and reactive ion etching. The book begins with a brief history of etching technology and the role it has played in the information technology revolution, along with a collection of commonly used terminology in the industry. It then moves on to discuss a variety of different etching techniques, before concluding with discussions of the fundamentals of etching reactor design and newly emerging topics in the field such as the role played by artificial intelligence in the technology. Atomic Layer Processing includes a wide variety of other topics as well, all of which contribute to the author's goal of providing the reader with an atomic-level understanding of dry etching technology sufficient to develop specific solutions for existing and emerging semiconductor technologies. Readers will benefit from: A complete discussion of the fundamentals of how to remove atoms from various surfaces An examination of emerging etching technologies, including laser and electron beam assisted etching A treatment of process control in etching technology and the role played by artificial intelligence Analyses of a wide variety of etching methods, including thermal or vapor etching, isotropic atomic layer etching, radical etching, directional atomic layer etching, and more Perfect for materials scientists, semiconductor physicists, and surface chemists, Atomic Layer Processing will also earn a place in the libraries of engineering scientists in industry and academia, as well as anyone involved with the manufacture of semiconductor technology. The author's close involvement with corporate research & development and academic research allows the book to offer a uniquely multifaceted approach to the subject.

This volume collects together for the first time a series of in-depth, critical reviews of important topics in dry etching, such as dry processing of III-V compound semiconductors, dry etching of refractory metal silicides and dry etching aluminium and aluminium alloys. This topical format provides the reader with more specialised information and references than found in a general review article. In addition, it presents a broad perspective which would otherwise have to be gained by reading a large number of individual research papers. An additional important and unique feature of this book is the inclusion of an extensive literature review of dry processing, compiled by search of computerized data bases. A subject index allows ready access to the key points raised in each of the chapters.

Semiconductor market value of 2018 was around 468.8 billion US dollars. It is increased for about 13.7% than year 2017. For 2019, it is estimated decrease about 10% to 13% which is 422 to 408 billion US dollars.This market is in a way winner takes all, for example, TSMC (Taiwan Semiconductor Manufacturing Company) which is the world leading semiconductor foundry company has more than 50% market share. Intel has more than 90% market share of personal computer CPU (Central Process Unit) for many years. However, the semiconductor IC process technology sometimes might change the rule of market. Just recently, AMD (Advanced Micro Devices, Inc.) has more than 17% market share of personal computer CPU because they use foundry of TSMC with 7nm EUV technology node (Extreme Ultraviolet, its wavelength is 13.5 nm, shorter wavelength has better critical dimension (CD) resolution for IC process).For the present time, there are four leading semiconductor companies in the world with EUV technology process node which are as follows: (1)Samsung: the world leading semiconductor IC process company for commodity IC such as DRAM、Flash memory and IC for cell phone. The world leading company in cell phone market share, Samsung has highest volume unit of mobile phone which is 75.1 million unit representing 23% of world market share. Samsung also is the leading company in OLED (organic light emitting diode) process technology and display panel which is more than 90% of world market share.(2)Intel: is the world leading company in personal computer CPU which has more than 90% market share of personal computer CPU (Central Process Unit) for many years. Intel is actually a world leading semiconductor IC technology in DRAM (many years ago) and Flash (at the present time) memory.(3)TSMC: TSMC is brief of Taiwan Semiconductor Manufacturing Company which is the world leading semiconductor foundry company has more than 50% market share. The author worked there for a few years as an R & D manager many years ago.(4)Micron: a world leading in DRAM and Flash memory IC.

This book has been written as part of a series of scientific books being published by Plenum Press. The scope of the series is to review a chosen topic in each volume. To supplement this information, the abstracts to the most important references cited in the text are reprinted, thus allowing the reader to find in-depth material without having to refer to many additional publications. This volume is dedicated to the field of dry (plasma) etching, as applied in silicon semiconductor processing. Although a number of books have appeared dealing with this area of physics and chemistry, these all deal with parts of the field. This book is unique in that it gives a compact, yet complete, in-depth overview of fundamentals, systems, processes, tools, and applications of etching with gas plasmas for VLSI. Examples are given throughout the fundamental sections, in order to give the reader a better insight in the meaning and magnitude of the many parameters relevant to dry etching. Electrical engineering concepts are emphasized to explain the pros and cons of reactor concepts and excitation frequency ranges. In the description of practical applications, extensive use is made of cross-referencing between processes and materials, as well as theory and practice. It is thus intended to provide a total model for understanding dry etching. The book has been written such that no previous knowledge of the subject is required. It is intended as a review of all aspects of dry etching for silicon semiconductor processing.

Microcomponents and microdevices are increasingly finding application in everyday life. The specific functions of all modern microdevices depend strongly on the selection and combination of the materials used in their construction, i.e., the chemical and physical solid-state properties of these materials, and their treatment. The precise patterning of various materials, which is normally performed by lithographic etching processes, is a prerequisite for the fabrication of microdevices. The microtechnical etching of functional patterns is a multidisciplinary area, the basis for the etching processes coming from chemistry, physics, and engineering. The book is divided into two sections: the wet and dry etching processes are presented in the first, general, section, which provides the scientific fundamentals, while a catalog of etching bath composition, etching instructions, and parameters can be found in the second section. This section will enhance the comprehension of the general section and also give an overview of data that are essential in practice.
