Particle Control for Semiconductor Manufacturing


Book Description

There is something Alice-in-Wonderlandish about powerful and vital computer systems being shut down by a microscopic mote that a hay-feverist wouldn't sneeze at, but as computer chips get smaller, smaller and smaller particles on their surface have a larger and larger effect on their performance.

Particle Contamination Control in Plasma Processing


Book Description

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.

Contamination Control for Semiconductor, FPD, and Suppliers


Book Description

This book is about contamination control, which is an important technology for semiconductor and FPD production. Contamination control technology is an essential technology for improving product yield and improving quality, which is essential for devices such as the latest semiconductors and OLEDs to succeed in mass production and make reasonable profits. Part 1 of this book was about particle control, starting with understanding the properties of particles, and then covering controlling particles through clean rooms and controlling particles beyond clean rooms. Part 2 of this book is about static electricity control, and introduces the part controlling the adsorption of particles by static electricity along with damage caused by static electricity. Together with our previous work, Cotamination Control for CEO and Engineers in IC & AMOLED Industry, we will continue our efforts to share the knowledge and experience necessary for the production of semiconductors and FPDs in a series with the theme of Contamination Control.




Contamination and ESD Control in High-Technology Manufacturing


Book Description

A practical "how to" guide that effectively deals with the control of both contamination and ESD This book offers effective strategies and techniques for contamination and electrostatic discharge (ESD) control that can be implemented in a wide range of high-technology industries, including semiconductor, disk drive, aerospace, pharmaceutical, medical device, automobile, and food production manufacturing. The authors set forth a new and innovative methodology that can manage both contamination and ESD, often considered to be mutually exclusive challenges requiring distinct strategies. Beginning with two general chapters on the fundamentals of contamination and ESD control, the book presents a logical progression of topics that collectively build the necessary skills and knowledge: Analysis methods for solving contamination and ESD problems Building the contamination and ESD control environment, including design and construction of cleanrooms and ESD protected environments Cleaning processes and the equipment needed to support these processes Tooling design and certification Continuous monitoring Consumable supplies and packaging materials Controlling contamination and ESD originating from people Management of cleanrooms and ESD protected workplace environments Contamination and ESD Control in High-Technology Manufacturing conveys a practical, working knowledge of contamination and ESD control strategies and techniques, and it is filled with case studies that illustrate key principles and the benefits of contamination and ESD control. Moreover, its straightforward style makes the material, which integrates many disciplines of engineering and science, clear and accessible. Written by three leading industry experts, this book is an essential guide for engineers and designers across the many industries where contamination and ESD control is a concern.
