Pulsed IV measurements enable modeling and design characterization engineers to accurately assess the intrinsic behavior of semiconductor devices by minimizing self-heating effects, capturing dynamic behavior under realistic operating conditions, modeling charge trapping effects, and extracting precise parameters for compact and behavioral models.
DC measurements can introduce significant self-heating, which distorts a device’s true electrical behavior. III-V devices (e.g., GaN) are susceptible to trapping effects, which can degrade performance and long-term reliability. Pulsed IV measurements provide critical insight into these effects, enabling the development of more predictive and robust device models. One of the main technical challenges in Pulsed IV testing is generating short-duration pulses with fast rise and fall times while maintaining signal integrity—ensuring the voltage and current waveforms settle properly without distortion. Additionally, the measurement system must precisely capture the voltage and current responses of the device under test (DUT) during these brief pulses. This demonstration shows the new Maury Pulsed IV measurement system that allows IV characterization from DC to Pulsed IV of 200ns. The setup supports gate sweeps from -30V to 30V up to 1.5A and drain sweeps from 0 to 280V up to 40A. A packaged GaN device will be used to test system capabilities up to 30V, while an external oscilloscope will be used to validate and showcase short-pulse performance.
