... joule heating, or electrostatic actuation using voltages to create electric fields. To qualify MEMS technology, these devices must undergo repeated characterization and testing and at both the die and system level. Electrical overstress (EOS) and electrostatic discharge (ESD) are two important tests...

... Abstract Frequently, Electrical Overstress (EOS) is understood in a similar context like Electrostatic Discharge (ESD). However, when looking deeper, only 3-5% of EOS failure signatures are caused by ESD. The dominant root causes can be found on system level – often inaccessible for the device...
