In situ SiN/AlN/GaN HEMTs with regrown contacts using selective etching

We show AlN/GaN high electron mobility transistors with in situ SiN for passivation and regrown n ^+ GaN ohmic contacts using a selective etching process that is more suitable for device scaling. The regrown ohmic contacts have a clean and sharp edge definition with a contact resistance of 0.25 Ω·mm...
