  • Water-level charged device model for electrostatic discharge test methods, and apparatus using same
    Publication number: 20100165537
    Abstract: A charged device model (CDM) electrostatic discharge (ESD) testing is carried out at wafer level. Wafer CDM pulses are repeatedly applied and monitored. The wafer CDM (WCDM) pulses are accomplished with a probe-mounted printed-circuit board and a high-frequency transformer that captures fast CDM pulses. Modeling of CDM and WCDM in the time and frequency domain illustrates the dominant effects, and shows that WCDM can reproduce all the major phenomena of package-level CDM testing.
