A textual content is required that connects fundamental EOS phenomena to as we speak’s real-world atmosphere. Whereas vital texts can be found as we speak to show consultants on electrostatic discharge (ESD) on-chip design, there’s a want for a basic understanding of EOS.

That is crucial for knowledgeable, non-expert, non-technical, and layman to grasp the issues dealing with the world as we speak.

As we speak, real-world EOS points encompass us; this happens in a producing atmosphere, energy sources, equipment, actuators, solenoids, soldering irons, cables, to lightning.

When there’s switching, poor grounding, floor loops, noise, and transient phenomena, there will probably be a possible for EOS of gadgets, elements, and printed circuit boards.

Therefore, there’s a want for consultants and non-experts to grasp what the problems that revolve round us are, and what we do to keep away from them. One of many key issues with this subject is the notion that EOS is troublesome to quantify and outline.

This notion was additionally true within the early days of ESD improvement. In consequence, there have been no textbooks on EOS at this date, and but it’s understood {that a} vital share of system and product discipline returns is EOS associated.

A second key downside is a perception that it’s troublesome to differentiate ESD failures from EOS. The rationale that this distinction is necessary is to outline the foundation reason behind the gadget, element, or system failures. In consequence, on this textual content, this will probably be re-emphasized.

A 3rd key downside is that the strategies and strategies to supply each EOS and ESD strong merchandise in the identical lecture, tutorial, supply, or textbook is rarely synthesized in a single dialogue.

That is additionally true that the dialogue and coaching on electromagnetic compatibility (EMC) and ESD are usually taught individually. This textual content has a number of objectives.

The primary objective of the textual content is to show the fundamentals and ideas of EOS and relate them to real-world processes in semiconductor manufacturing, dealing with, and meeting The second objective of the textual content is to supply a powerful technical base for quantification of EOS, highlighting each mathematical and bodily evaluation.

On this vogue, it’s vital to grasp the position and relationship of thermal physics. The third objective of the textual content is to attract a distinction between EOS and ESD. This will probably be achieved by specializing in the heart beat waveform and time scales.

The textual content will always reinforce this distinction by the sources, to the mathematical fashions.

The fourth objective is to debate the inter-relationship to different disciplines, reminiscent of electromagnetic interference (EMI), electromagnetic compatibility (EMC), and latchup. The fifth objective is to reveal the reader to EOS testing and requirements of each semiconductor chips and techniques.

On this part, we’ll once more distinguish between the EOS and ESD checks and requirements. The fifth objective is to reveal how one can defend semiconductor chips and techniques from EOS.

The sixth objective is to reveal how one can defend semiconductor chips and techniques from each EOS and ESD occasions. The seventh objective is to show EOS points in several expertise sorts for digital, analog, and energy electronics.

The eighth objective is to spotlight electrical design automation (EDA) strategies to supply EOS strong merchandise. On this part, we’ll once more draw distinctions of EDA options for EOS, ESD, and latchup.

The ninth objective is to debate an EOS program administration for manufacturing environments from measurements to audits, to make sure an EOS Protected Space.

The tenth objective is to supply a glimpse into the current and future with new nano-structures and nano-systems that lie forward. This may present perception into what will probably be wanted sooner or later, in addition to the magnitude of the EOS concern within the coming years.
