Last Updated on Wednesday, May 20, 2020 17:39 Industry Council Launches Survey on Latch-up Latch-up, which is the triggering of a low-ohmic path between power supply rails that can either damage the IC or make the IC inoperable, became a reliability concern in the mid 80's. The first practical Industry IC latch-up testing method with injection current requirement, JESD78, was published in the mid 90's by JEDEC and has been revised five times by the JESD78 Working Group. Some more info is available here. For various reasons including technology scaling, increasing amounts of integration, and the complexity and variety of semiconductor components, the standard has faced challenges addressing the needs of the increasingly diverse semiconductor product space. Some of those challenges are: It is unclear how this test method correlates to real threats.In many low-voltage cases, the current injected in the IO is very limited.There are many technicalities that can disqualify a result. Examples are the active state of the DUT, the definition of special pins and power supply instability. This has prompted the Industry Council on ESD Target Levels, working with the JESD78 Working Group, to re-evaluate the latch-up standard in today's context. To understand more on how people are dealing with the topic and to get more information on how the Industry uses latch-up testing results and to understand what industry expects from latch-up testing, the Industry Council has set up a survey. ...

Last Updated on Thursday, August 25, 2016 18:20 White Paper 4: Understanding Electrical Overstress - EOS Revision 1.2 has been released! Begun as an effort by the Council in 2013 to compile survey feedback and consultation from leading experts in the field from both the system OEM and IC supplier sides, we are pleased to announce the final JEDEC release of White Paper 4 as JEP174. This 189 page document is a major achievement of the Industry Council team and thanks go out to all contributing members, authors, chapter owners, industry advisers and reviewers for their continued support and commitment. This is also a major leap for the industry in improving collaboration between suppliers and system customers to prevent EOS events and damage. The document is also approved by the ESD Association. A first comprehensive overview of the results of WP4 was presented to the public during IEW in May, 2016. A full customer presentation based on WP4 will soon be forthcoming.
Last Updated on Monday, October 08, 2012 22:04 White Paper 3 Part 2 on System ESD: "Implementation of Effective ESD Robust Designs" has been released! After more than a year of preparation effort by the Council, combined with feedback and consultation from leading experts in the field from both the system OEM and IC supplier sides, we are pleased to announce the release of Part II. This 153 page document continues from Part I and reviews the state of the art in ESD/EMI analysis and development techniques, "System Efficient ESD Design (SEED)" methodologies, and future challenges in the ESD/EMI field. It has been approved by JEDEC and will soon be published as JEP162.

Last Updated on Wednesday, November 30, -0001 00:00 The Industry Council met for 1.5 days at the JA Nugget in Sparks (Reno) Nevada, Oct 7-8. We're close to finalizing White Paper 3 (WP3), Part 1, on System ESD. We now continue into Part 2 of WP3 and have outlined what we want in the document. WP3 Part 1 will be posted soon, stay tuned for a link. Posted by Tim Maloney at 3:32 PM
