Understanding Failure Mechanisms 3-Day Course

Course Description

Failure mechanisms in reliability engineering will be introduced. The methods of the physics of failure of devices, materials, components and systems are reviewed. The main emphasis will be given to basic degradation mechanisms through understanding the physics, chemistry and mechanics of such mechanisms. Mechanical failures are introduced through understanding fatigue, creep and yielding in materials, devices and components. Physical or chemical related failures are introduced through a basic understanding of physical mechanisms such as diffusion, electromigration, defects and defect migration. Failure mechanisms observed in real devices and systems will also be presented. Problems related to manufacturing and microelectronics will be analyzed.

Who Should Take the Course

This program is for electrical engineers and materials engineers who wish to understand the basics of failure mechanisms.

What the Student Will Learn

The student will leave the course with an understanding of the basics of failure mechanisms and life modeling.

Aris Christou, Ph.D.

Picture of Christou Professor Aris Christou was the Chairman of the University of Maryland, Materials and Nuclear Engineering Department (until July 2003), and presently holds professorial appointments in the Department of Materials Science and Engineering and Mechanical Engineering. Professor Christou received his Ph.D. in Materials Science from the University of Pennsylvania in 1971. He presently conducts research in compound semiconductor materials and process science, radiation effects in materials and devices, manufacturing science, and reliability. Dr. Christou was previously a Professor of Electronic Materials at Rutgers University, and research scientist at the Naval Research Laboratory. He has authored two books and has been the editor of three others. Dr. Christou has more than 150 publications in archival journals and 14 patents (including two pending), and has organized international conferences in GaAs devices, materials and reliability. Dr. Christou is a Fellow of the IEEE, a Fullbright Fellow, a recipient of the DoD-Berman Publication Awards, and an IEEE Guest Lecturer. Professor Christou's technical contributions encompass the development of materials surface and interface science and methodologies for achieving reliable high frequency devices, optoelectronic devices and circuits. Professor Christou's contributions established the critical relationships which exist between materials, materials surfaces and interfaces, process science, and reliability.
