Abstract

Damage-free metal-assisted chemical etching (MacEtch) was used to fabricate InP junctionless FinFETs with ultra-high aspect ratio (∼ 45:1) fins. For devices with Lg = 560 nm, 20 - 32 nm fin width, and 600 nm active fin height, Ion/Ioff ∼ 106, and near-ideal subthreshold swing (70 mV/dec) were achieved.
