Voltage differentials exceeding 30,000 volts per centimeter may lead to
a charge transfer (electrostatic discharge, lightning, spark-over).
Integrated circuits (logical circuits and microprocessors) are used in
order to implement a wide variety of functions in a device. The circuits
must be miniaturized to a very high degree in order to include as many
functions as possible on these chips. This leads to structure thicknesses
as low as a few ten thousandths of a millimeter. Integrated circuits that
are connected to wires leading externally are therefore particularly at
risk from electrostatic discharge.
Even voltages that are imperceptible to the user can cause breakdown
of the structures, thus leading to a discharge current that melts the chip
in the affected areas. Damage to individual integrated circuits may
cause malfunction or failure of the unit.
