Electrostatic Discharge [ESD]

Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.

Grounding is often viewed from separate points of view - safety, ESD, or EMI.  This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.

A fully functional ESD floor prevents static generation and provides an effective path to ground for personnel and equipment. Many conductive and dissipative floors meet STM 7.1 resistance parameters in ANSI/ESD S20.20 but fail to provide adequate electrical contact for grounding equipment with conductive casters and drag chains.

High reliability organizations (HROs) typically implement stringent static control programs to mitigate the risks of catastrophic and/or life-threatening failures. This article describes some of the considerations to consider for static control flooring in these more demanding environments.

Within the past 18 years, many studies exploring 3 µm to 7 nm technologies have demonstrated the excellent correlation of CC-TLP with CDM in terms of stress current failure threshold as well as electrical failure and physical damage signature.
