• Ultra-Sensitivity Trends and CDM
T. Dangelmayer
The electronics industry faces a double challenge: increasing use of ultra sensitive devices and lack of experience with the Charge Device Model (CDM). This class will give you the background to understand the challenges and prepare to meet them. Case studies will illustrate how CDM failures can persist even with a robust HBM program in place. A series of photographs of common CDM issues in manufacturing will enable students to visualize how to implement CDM controls. A brief summary of the work by the Industry Council on ESD Target Levels will be included.
• Charged Board Events: A Growing Industry Concern
T. Welsher
A charged board stores much more energy than a device (IC) because its capacitance is many times larger. In fact, the charge (energy) transferred in the event is so large that it can cause EOS-like failures to the components on the board. In this seminar, this board-level ESD event will be compared with the component level CDM ESD event. The waveforms from both ESD events will be compared and it will be shown that for the same voltage, the current in the board-level ESD event will be much higher than that from the chip-level ESD event. A summary of literature and industry data will be given. It is suggested that failure analysts give stronger consideration to these types of board level events before assigning an EOS diagnosis to the failure. This will support more effective root cause analysis and prevention of these failures.
• Susceptibility Testing of Devices and Systems
M. Hopkins
There is a disconnect in the EMC (ElectroMagnetic Compatibility) world between system manufacturers testing systems for upset and device manufacturers testing devices for failure. Some system level manufacturers are pushing device manufacturers to test semiconductor devices using system level compliance standards – specifically, IEC 61000-4-2 for ESD (Electrostatic Discharge). Product manufacturers would like to believe that if devices are qualified to IEC standard(s), finished products will likewise be qualified. Unfortunately, there is a fundamental difference between system level and device level testing; fortunately however, this difference can be bridged using new susceptibility scanning techniques on the board or device. Until now, EMC and ESD susceptibility testing at the device level has not been done. In this course, we will cover scanning methods (using a magnetic field noise source and probe) that allow identification of susceptible devices in a system, sensitive areas/pins of devices and associated circuitry.
• Advanced ESD/EMI Auditing Techniques
A. Wallash
In order to solve today’s ESD problems, ESD auditing must provide data on not only the static charge and voltage on tooling and devices, but also the transient voltage, current and electromagnetic field interference (EMI) up to at least 1 GHz. This practical course will teach how to use a variety of charge, current, voltage and E-field probes to understand the ESD/EMI threats during processing of ESD sensitive devices.
• ESD Problem Solving
J. Kinnear
Its Friday at 3:00 and your quality manager calls you, “We are having ESD failures”. Now what do you do? Go out and audit your line? This online course will outline the steps that you should take to examine your process before you audit your line or even leave your office. A systematic approach will be explained on the logical steps to take for ESD troubleshooting. Only after such an analysis should you go on the line for measurements or assessments.
• The Good, The Challenges, and the Improvements in CDM ESD Testing
L. G. Henry
CDM ESD Stress Testing of ICs has changed and improved since CDM standards were first published in 1995 (JEDEC) and 1999 (ESDA). The method on which these standards are based was introduced in 1989. The purpose of this Webinar is to present these improved changes and at the same time teach the basics of good CDM stress testing of ICs as required by the CDM standard. Minimum equipment requirements to produce an adequate CDM waveform will be discussed. The need for good and proper equipment/tester qualification, calibration and periodic verification will be presented. It will be shown how the CDM stress testing requirements combined with proper stress testing procedures will lead to good and reliable qualification of product. Finally, improvements associated with the most recent releases of 2 documents ( the ANSI/ESD CDM-5.3.1 standard and the JEDEC- CDM JESD-22C-101E- standard) will be presented and the commonality between the 2 documents will be emphasized.
• Electrostatic Attraction
C. Newberg
This training will cover the causes and effects of electrostatic attraction (ESA) and the solution to ESA problems in a variety of industries. Electrostatic attraction problems plague industries from photographic to medical and electronics. In the electronics industry alone, electrostatic attraction problems can be found in disk drive assembly, wafer fabrication and PC board assembly. The solutions to these problems can be found by applying a combination of the fundamentals of electrostatics and contamination control. An overview of clean rooms, ionization, materials and the control of static electricity will be presented. Real world problems and their solutions will be discussed using case histories.
I. Basics of electrostatics
II. Types of bonding
III. Physics of electrostatic attraction
IV. Industrial problems
V. Solving electrostatic attraction problems
VI. Case studies
• Developing a Compliance Verification Program
J. Kinnear
Compliance verification is one of the required elements in the ANSI/ESD S20.20 standard. Without periodic verification of the ESD materials used within an Electrostatic Protected Area (EPA) programs can degrade over time. This course will cover some of the items that need to be considered for a successful compliance verification program.
Topics covered in this program include,
• What is a compliance verification program?
• What is the difference between product qualification and compliance verification?
• How does the ESD program manager determine the frequency of testing?
As part of the course, common ESD control items will be covered and how to do the testing efficiently and to meet the requirements of ANSI/ESD S20.20 and TR53. Questions can be submitted in advance to be answered as part of the course.
• Compliance Verification: Pitfalls of Auditing
G. Hansel
Accurate data is the foundation of effective ESD Program Management. Therefore, it’s important to have confidence in the measurements. Choosing the correct type of equipment for each measurement is also important and not always obvious.
The class will cover the correct use of static locators, resistance meters, event detectors, and how to use ionizers effectively. We will discuss the various pitfalls of commonly used instruments, and the invalid test results that can result. For instance, static locators can yield totally invalid readings when used incorrectly due to voltage suppression. What you learn will help you avoid frequently encountered auditing problems, and improve your compliance verification program.
• Device Testing Correlation to Root Cause Failure Analysis
L. G. Henry
ESD Device Stress Testing is known to benefit at least three areas: qualifying the product, simulate failures from factory or field, and to improve the design of the product. Three ESD models (HBM, MM and CDM) are used to simulate failures and to differentiate between the different types of ESD failures and also to differentiate the ESD type failures from EOS-type failures. Even though there are no Failure Analysis standards for ESD, there is enough archived data, published data and experience to show correlation exists between the ESD Stress testing types, the physical failure types and the eventual root cause. The type of equipment required to get to the physical failures and see the failures will be emphasized. The class will show how to correlate each ESD model stress testing results to the physical failure type and the physical failure location on the die. A real example will be used to show how the ESD stress testing lead to the root cause of a field failure.
• Highlights and key concepts of Footwear/Flooring standards
K. Duncan
Footwear/Flooring Systems can play a major role in a successful ESD Control Program. How do you properly select and implement an ESD Footwear/Flooring System? This course will provide an overview of the concepts and Standards used for product qualification of footwear and flooring, as well as compliance verification of a Footwear/Flooring System.
This course will focus on the Footwear/Flooring Standards and Standard Test Methods related to selecting and implementing a Footwear/Flooring System for use an ANSI/ESD S20.20 Control Program.
• Grounding in an Electrostatic Protected Area
D. Swenson
Grounding is perhaps the single most important technical aspect in establishing an electrostatic protected area.
The ESD Association grounding standard ANSI/ESD S6.1 provides potential users with specifications, guidance and suggestions for implementing a grounding/bonding system suitable for nearly any imaginable application. This information is not found anywhere else in industry literature.
This web-based training session will include answers to the following questions:
•What grounding method is appropriate for a work area?
•What measurements are needed?
•Are there any new terms or definitions?
•What are the proper ways to ground personnel in the workplace?
• Air Ionization: Theory and Practice
A. Steinman
Solve Problems Caused By Static Charge With Air Ionization
The primary method of static charge control is direct connection to ground for conductors,
static dissipative materials, and personnel. But a complete static control program must also
deal with isolated conductors, insulating materials, and moving personnel that cannot be
grounded. Air ionization can neutralize the charge on insulated and isolated objects. This
seminar will cover the following topics:
•Importance of Ionization in a Static Control Program
•Ionization Fundamentals and Methods
•Ionizer Selection Criteria and Examples
•ANSI/ESD S20.20 Static Control Program Requirements for Ionization
• Electrostatic Discharge Effects In Integrated Circuit Technologies
C. Duvvury
This course will outline the fundamentals of ESD phenomena and the methods to control the effects of ESD for safe manufacturing of IC devices. The training material will include the nature of ESD transients, their impact on the IC devices, common methods to test for ESD at both the device level and the system board level, and the overall protection techniques. Finally, the course will review the advances in IC technologies that lead to future challenges for ESD development and the resulting important technology roadmap established by the ESD Association.
