Gearing Up for Parametric Test's High Voltage Future
Many parametric test engineers are learning to cope with new high voltage process requirements. Not surprisingly, high voltage processes require high voltage parametric testing for process control and reliability monitoring. Part of the challenge lies in the fact that these new high voltage requirements add to the list of parametric tests rather than replacing some portion of it. In many if not most cases, the high voltage transistors are controlled by complex logic that requires low voltage/low current parametric test. Consequently, both high voltage and logic tests have to be addressed within the same test plan while minimizing impact on throughput.
