Model 400S allows zapping HBM or MM ESD stress to various shape DUT, then automatically detect damage or degradation by very little programming. Even designer simply tests the ESD performance of a new design any time.
ESD Performance Test from Wafer to package
Process Monitoring by periodical wafer test
Allows correlation test between die location and ESD performance
Multiple return allows ESD current path verification
Enables rapid ESD performance test of new devices
Decreases device development time
