Making the "Perfect Switch" Reality: New Techniques for Wafer-Level Testing of Power Semiconductors

For more than 50 years, power semiconductor manufacturers have been pursuing the elusive goal of creating the “Perfect Switch” that offers high voltage blocking capabilities in the off-state, zero resistance in the on-state, high switching speeds, long-term reliability, and low cost. The adoption of wide bandgap materials such as SiC and GaN enables greater efficiency, but how do you keep production costs low while meeting these demanding measurement requirements? Join us as we discuss how to perform fully automated, wafer-level measurements from pico-amps to kilo-volts in a single-pass without manually changing the test set-up or equipment.
