Plasma processing is a central technique in the fabrication of semiconductor devices. This self-contained book provides an up-to-date description of plasma etching and deposition in semiconductor fabrication. It presents the basic physics and chemistry of these processes, and shows how they can be accurately modeled. The author begins with an overview of plasma reactors and discusses the various models for understanding plasma processes. He then covers plasma chemistry, addressing the effects of different chemicals on the features being etched. Having presented the relevant background material, he then describes in detail the modeling of complex plasma systems, with reference to experimental results. The book closes with a useful glossary of technical terms. No prior knowledge of plasma physics is assumed in the book. It contains many homework exercises and serves as an ideal introduction to plasma processing and technology for graduate students of electrical engineering and materials science. It will also be a useful reference for practicing engineers in the semiconductor industry.

Plasma processing is used for (approximately)35% of the process steps required for semiconductor manufacturing. Recent studies have shown that plasma processes create the greatest amount of contaminant dust of all the manufacturing steps required for device fabrication. Often, the level of dust in a plasma process tool exceeds the cleanroom by several orders of magnitude. Particulate contamination generated in a plasma tool can result in reliability problems as well as device failure. Inter-level wiring shorts different levels of metallization on a device is a common result of plasma particulate contamination. We have conducted a thorough study of the physics and chemistry involved in particulate formation and transport in plasma tools. In-situ laser light scattering (LLS) is used for real-time detection of the contaminant dust. The results of this work are highly surprising: all plasmas create dust; the dust can be formed by homogeneous as well as heterogeneous chemistry; this dust is charged and suspended in the plasma; additionally, it is transported to favored regions of the plasma, such as those regions immediately above wafers. Fortunately, this work has also led to a novel means of controlling and eliminating these unwanted contaminants: electrostatic {open_quotes}drainpipes{close_quotes} engineered into the electrode by means of specially designed grooves. These channel the suspended particles out of the plasma and into the pump port before they can fall onto the wafer.

Plasma processing of materials is a critical technology to several of the largest manufacturing industries in the worldâ€"electronics, aerospace, automotive, steel, biomedical, and toxic waste management. This book describes the relationship between plasma processes and the many industrial applications, examines in detail plasma processing in the electronics industry, highlights the scientific foundation underlying this technology, and discusses education issues in this multidisciplinary field. The committee recommends a coordinated, focused, and well-funded research program in this area that involves the university, federal laboratory, and industrial sectors of the community. It also points out that because plasma processing is an integral part of the infrastructure of so many American industries, it is important for both the economy and the national security that America maintain a strong leadership role in this technology.

The MURI Center on Modeling and Control of Plasma Processing at the University of Michigan started in September, 1995, and concluded technical work at the end of August 2001. As the name indicates, the major research goals of the center are in the areas of modeling and control of plasma deposition and etching processing. These plasma processes are used extensively in the manufacture of integrated circuits as well as active matrix liquid crystal displays. These applications areas motivate our selection of research problems in modeling and control. Significant accomplishments were made in all of these areas (as will be discussed in the body of the report) Particular program highlights include: (1) An optical technique was developed to monitor in situ and in real time the critical dimensions and wall-shapes of evolving features in reactive ion etchers. An advanced signal processing scheme was devised to use this technique to perform the first fully-automated etch-to-target-dimension etches. One-nanometer-level (or better) accuracy was demonstrated enabling possibilities for extremely high accuracy semiconductor fabrication control. (2) The state-of-the-art of 1st principles plasma equipment modeling was advanced so that the entire system of the sensors, plasma process equipment, and control systems could be modeled numerically. (3) Novel RF Sensing to non-invasively measure the electrical state of plasma systems was developed and applications to detecting common faults were demonstrated. (4) Improved statistical methods for detecting and identifying the causes of spatially clustered defects in semiconductor manufacturing. (5) Development of a novel ion-beam modification process for the deposition of Al films which are more resistant to grain-growth.

Presents state-of-the-art research in microelectronic processing for very large scale integration. Emphasizing applications and techniques, this book provides considerable insight into Japan's technological effort in this important area of science. Focuses on research involving plasma deposition and dry etching. Considerable attention is devoted to MOS gate fabrication, the studies of the influence of process parameters on electrical properties, dry processing technologies, and the theory of plasma chemical reactions.

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.
