Conformal Passivation of Multi-Channel GaN Power Transistors for Reduced Current Collapse

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Halil Kerim Yildirim, Luca Nela, Catherine Erine, Kai Cheng

Multi-channel power devices, in which several AlGaN/GaN layers are stacked to achieve multiple two-dimensional electron gases (2DEGs), have recently led to a significant increase in the device conductivity while maintaining high breakdown voltage, resultin ...

1200 V Multi-Channel Power Devices with 2.8 Ω•mm ON-Resistance

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Catherine Erine, Kai Cheng, Minghua Zhu

Here we report novel multi-channel AlGaN/GaN MOSHEMTs with high breakdown voltage (V BR ) and low ON-resistance (R ON ). The multi-channel structure was judiciously designed to yield a small sheet resistance (R s ) of 80 Ω/sq using only four 2DEG channels, ...
