Abstract

This experimental study reports ESD behavior of novel designs of GaN Schottky diodes. Impact of electro-thermal transport, device degradation and trap generation on its ESD robustness is analyzed. Role of interface traps in ESD failure of GaN Schottky diode is investigated. Transition from soft-to-hard failure, which is found to depend on diode area, presence of traps and diode design is discussed. Unique degradation trends, cumulative nature of degradation and trap assisted failure modes are discovered.
