About the Author This article was prepared on behalf of the ESD Association by Dr. Leo G. Henry, an IEEE Senior member. He is a member of the ESDA’s Board of Directors, with Chair responsibilities for the National ESD Symposium Workshop and the Device Design Certification Program. Dr. Henry is also chair/facilitator for the ESDA’s Device Testing Standard Committee (WG-5.0) that has several subgroups (HBM, CDM, MM, HMM, TLU and TLP). Dr. Henry is presently the Chief Engineer at ESD/TLP Consultants LLC, located in Silicon Valley, Fremont, CA. He has B.S. and M.S. degrees in Physics from the University of the West Indies, and M.S. and Ph.D. degrees in Materials Science & Engineering from U.C. Berkeley, CA. He can be reached at 510-657-5252 (office) or 510-708-5252 (mobile), and at leogesd@pacbell.net or leogesd@ieee.org. the protection structure. It is not only at what voltage will the ESD structure turn on, but also how fast the transient must be before the structure turns on. A simple look at the I-V curves (shown in Figure 1) from a device stressed on a TLP simulator/tester shows that, at different rise times ( 20.0 nsec , 2.0 nsec and 0.20 nsec), the turn on voltages are quite different. About the ESD Association Founded in 1982, the ESDA is a not-for-profit, professional organization directed by volunteers dedicated to furthering the technology and understanding of electrostatic discharge. The Association sponsors education programs, develops ESD standards, holds an annual technical symposium, and fosters the exchange of technical information among its members and others.

Website: www.esda.org. Q: A: CDM failure is the future failure? You are so correct that the World Council on ESD, a consortium of 18-20 of the top IC manufacturing companies in the world and 11 associate members, has made their general goal/mission to review the ESD robustness HBM, MM and CDM requirements of modern IC products for allowing safe handling and mounting in an ESD protected area. Q: A: What type of industry would be most affected by CDM failure in the future? The storage industry (hard disk drive, etc.) has been impacted by this much lower level CDM ESD failure threshold for many years now, so their learning curve may be ahead of the electronics and flat panel industries, which include the medical products, the telecommunications products, the consumer electronics/products and the computer products etc. n NOVEMBER 2007 CONfORMity 23 http://www.esda.org http://www.esda.org
