Analysis of the charge transfer of models for electrostatic discharge (ESD) and semiconductor devices

Various models are used to simulate the electrostatic discharge (ESD) event associated with semiconductor devices; these include the human body model (HBM), the charged device model (CDM), and the field induced charged device model (FCDM). Maxwell's method is used to analyze these models to determine device potentials and the transfer of charge during typical discharges; existing test methods are also examined. A charge injection test method is introduced which provides control of the charge transferred to the device under test; it is proposed as a means to study charge related phenomena due to ESD.
