System Level Direct PIN ESD (SL-DPE) Survey Call to Action The Industry Council White Paper 3, Part 3 (published by JEDEC as JEP164) has discussed the industry practice to apply IEC 61000-4-2 pulses to pins of a system port. While this practice is widely used, there is neither a standard test procedure nor a common understanding of the robustness levels. This survey should help to collect the approaches in industry and to consolidate them. It will provide the base for a White Paper recommending an industry standard procedure. Call To Action! Please Click on this Link to take the Survey Now! The newly coined term "System level direct PIN ESD (SL-DPE)" testing describes a modification of the IEC 61000-4-2 test standard or test methods that are derived from the standard applied to system port pins. While not directly supported by IEC 61000-4-2 the direct pin stress testing is often used to stress: LAN pins USB interfaces Automotive LIN or CAN interfaces A schematic view of a system level direct pin ESD stress testing is provided in Figure 1. <figure > <img src="/shared/sl-dpe-fig1.png" /> <figcaption>Figure 1: Schematic view of system level direct pin ESD stress testing</figcaption> </figure><p> A few examples of real world concerns of ESD discharge to port interfaces are shown in Figures 2-4.

Last Updated on November 29, 2023 White Paper 2 Part II: Die-to-Die Interfaces - A Case for Lowering Component-level CDM ESD Specifications and Requirements has been Released Revision 1.1 - Adopted as JEDEC JEP196 November 2023 This white paper on die-to-die (D2D) interfaces is an extension of the second revision of White Paper 2 on CDM target levels released in 2021. It addresses the need for a clear CDM target roadmap for D2D interfaces. D2D interfaces are the central intellectual property (IP) blocks for a heterogeneous integration architecture. This heterogeneous integration technology, with several variants of 2.5D and 3D package integration schemes, is the key enabler for the continuation of Moore’s law and will drive the growth of the semiconductor market in the coming years. This white paper presents an industry-wide survey on the relevance of industry-aligned D2D CDM targets and the currently used targets for D2D interfaces.
Last Updated on Monday, April 25, 2022 White Paper 5 - Survey on Latch-up Testing Practices and Recommendations for Improvements Revision 1.0 has been released!
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, February 1, 2021 Industry Council Survey on Latch-up [THIS SURVEY IS NOW CLOSED] 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 ...

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
Last Updated November 11, 2020 White Paper 3 (WP3), Part 3, on System ESD testing with IEC61000-4-2 has been released.
Last Updated on Friday, May 14, 2021 01:44 White Paper 3 Part III (WP3P3) on System ESD testing with IEC61000-4-2 has been updated. WP3P3 proposes a consistent and standardized contact discharge test for System Efficient ESD Design (SEED) and also addresses the many industry difficulties and shortcomings with air discharge testing. White Paper 2 (WP2) on CDM Target Levels has also been updated to address the realities of optimizing CDM levels for safe manufacturing within the constraints of very high speed serial interfaces and 2.5D and 3D processes in 7nm and beyond.
