Investigation of dynamic r on stability and hot electrons reliability in normally-off AlGaN/GaN power HEMTs
The current collapse and hot electron effect of 100 V normally-off GaN power HEMTs are investigated. The 100 V GaN-on-Si power HEMTs are fabricated on an industrial 200 mm Si CMOS compatible technology platform. The double pulse test (DPT) and the dynamic high temperature operating life (DHTOL) test...

520 | |a The current collapse and hot electron effect of 100 V normally-off GaN power HEMTs are investigated. The 100 V GaN-on-Si power HEMTs are fabricated on an industrial 200 mm Si CMOS compatible technology platform. The double pulse test (DPT) and the dynamic high temperature operating life (DHTOL) test are implemented to verify the dynamic on-resistance (dynamic R on ) stability. Wafer level hot electron reliability test is performed to investigate the effect of high electric field and high current on GaN power HEMT. It is proved that the dynamic R on stability of 100 V GaN power HEMT is qualified (R on /R ini, static < 1.2) when the drain-source off-state voltage (V dsoff ) is less than 80 V. It is shown that the dynamic R on degradation of GaN device is recoverable by means of annealing. Hot electrons reliability is dominated by the high electric field at drain edge and the high current which is source injected electrons flowing to the drain. It is demonstrated that the V th drift and R on degradation are extraordinary serious under semi on-state stress condition with V dsoff = 60 V. | ||

The 100 V GaN-on-Si power HEMTs are fabricated on an industrial 200 mm Si CMOS compatible technology platform. The double pulse test (DPT) and the dynamic high temperature operating life (DHTOL) test are implemented to verify the dynamic on-resistance (dynamic R on ) stability. Wafer level hot electron reliability test is performed to investigate the effect of high electric field and high current on GaN power HEMT. It is proved that the dynamic R on stability of 100 V GaN power HEMT is qualified (R on /R ini, static < 1.2) when the drain-source off-state voltage (V dsoff ) is less than 80 V. It is shown that the dynamic R on degradation of GaN device is recoverable by means of annealing. Hot electrons reliability is dominated by the high electric field at drain edge and the high current which is source injected electrons flowing to the drain. It is demonstrated that the V th drift and R on degradation are extraordinary serious under semi on-state stress condition with V dsoff = 60 V.

Investigation of dynamic r on stability and hot electrons reliability in normally-off AlGaN/GaN power HEMTs |
abstract |
The current collapse and hot electron effect of 100 V normally-off GaN power HEMTs are investigated. The 100 V GaN-on-Si power HEMTs are fabricated on an industrial 200 mm Si CMOS compatible technology platform. The double pulse test (DPT) and the dynamic high temperature operating life (DHTOL) test are implemented to verify the dynamic on-resistance (dynamic R on ) stability. Wafer level hot electron reliability test is performed to investigate the effect of high electric field and high current on GaN power HEMT. It is proved that the dynamic R on stability of 100 V GaN power HEMT is qualified (R on /R ini, static < 1.2) when the drain-source off-state voltage (V dsoff ) is less than 80 V. It is shown that the dynamic R on degradation of GaN device is recoverable by means of annealing. Hot electrons reliability is dominated by the high electric field at drain edge and the high current which is source injected electrons flowing to the drain. It is demonstrated that the V th drift and R on degradation are extraordinary serious under semi on-state stress condition with V dsoff = 60 V. |
