EOS, ESD Issues In Manufacturing
Electrical Overstress (EOS) and Electrostatic Discharge (ESD) account for most of the field failures observed in the electronics industry. Although EOS and ESD damage can at times look quite similar to each other, the source each and the solution can be quite different. Therefore, it is important to be able to distinguish between the two mechanisms. The semiconductor industry needs knowledgeable engineers and scientists to understand these issues. EOS, ESD Issues in Manufacturing is a 2-day course that offers detailed instruction on EOS, ESD and how to distinguish between them. This course is designed for every manager, engineer, and technician concerned with EOS, ESD, analyzing field returns, determining impact, and developing mitigation techniques.
Participants learn to develop the skills to determine what constitutes a good ESD design, how to recognize devices that can reduce ESD susceptibility, and how to design new ESD structures for a variety of technologies include latest Cu Pillar, TSV and FinFET technologies.
- Overview of the EOS Failure Mechanism. Participants learn the fundamentals of EOS, the physics behind overstress conditions, test equipment, sources of EOS, and the results of failure.
- Overview of the ESD Failure Mechanism. Participants learn the fundamentals of ESD, the physics behind overstress conditions, test equipment, test protocols, and the results of failure.
- ESD Circuit Design Issues. Participants learn how designers develop circuits to protect against ESD damage. This includes MOSFETs, diodes, off-chip driver circuits, receiver circuits, and power clamps.
- How to Differentiate. Participants learn how to tell the difference between EOS and ESD. They learn how to simulate damage and interpret pulse widths, amplitudes and polarity.
- Resolving EOS/ESD on the Manufacturing Floor. Participants see a number of common problems and their origins.
- The seminar will provide participants with an in-depth understanding of electrical overstress, the models used for EOS, and the manifestation of the mechanism.
- Participants will understand the ESD failure mechanism, test structures, equipment, and testing methods used to achieve robust ESD resistance in today’s components.
- The seminar will identify the major issues associated with ESD, and explain how they occur, how they are modeled, and how they are mitigated.
- Participants will be able to identify basic ESD structures and how they are used to help reduce ESD susceptibility on semiconductor devices.
- Participants will be able to distinguish between EOS and ESD when performing a failure analysis.
- Participants will be able to estimate a pulse width, pulse amplitude, and determine the polarity of an EOS or ESD event.
- Participants will see examples of common problems that result in EOS and ESD in the manufacturing environment.
