Get a better understanding of how CMOS circuits work and, more importantly, how they fail!

CMOS manufacturing environments are rife with symptoms that can indicate serious test, design, or reliability problems. CMOS Electronics: How It Works, How It Fails provides both practitioners and students in the industry with the electronic knowledge that relates not just to the design of a product, but other important aspects of manufacturing such as testing, reliability, failure analysis, yield–quality issues, and common problems that may occur during production.

The majority of those who work in the CMOS integrated circuit (IC) industry have educational backgrounds other than electrical engineering. The first part of the book assumes little knowledge of circuitry and transistors, covering the relevant basic electronics of CMOS ICs at a tutorial level or as a quick review for electrical engineers. The second half offers thorough descriptions of failure mechanisms that both audiences can appreciate.

A valuable addition to the CMOS literature, CMOS Electronics addresses such common questions as:

  • Is the symptom an outcome of random defects, or is it symptomatic with a common failure signature?
  • Why doesn’t my test program detect certain defects?
  • Are my test escapes a reliability problem?
  • Is the defect a bridging problem, an open circuit problem, or a subtle speed–related problem?

Providing rapid guidance to the nature of these problems and offering unique descriptions of many circuit failure mechanisms found previously only in research papers, CMOS Electronics is an essential text for practitioners in the CMOS industry, or students headed there.
