The GaN high electron mobility transistor (HEMT) has been commercialized as a power device with performance superior to Si devices in the voltage classes from 15 V to 900 V [1]. Most of commercial enhancement-mode (E-mode) HEMTs comprise a planar p-GaN gate. Recently, 3-D gate stacks, such as FinFET and tri-gate structures, have been introduced to lateral GaN HEMTs. They can realize superior gate controllability and E-mode operation with a higher current on/off ratio and lower gated channel resistance [2].The post 3D TCAD Simulation of Gallium Nitride Tri-gate Junction HEMT appeared first on Silvaco.
