Influence of the device package on the results of CDM tests-consequences for tester characterization and test procedure

The results of CDM device level tests-opposite to SDM-are strongly influenced by the device packages. An investigation of different types of devices (technology and package) shows that the CDM withstand voltage depends on the peak current of the discharge current waveform and not on the charge which is stored on the device after charging. This information has important consequences for tester characterization and the test procedure. Furthermore, peak current investigation gives a chance to extrapolate CDM results from one specific package to other packages and even perhaps for SDM/CDM correlation.
