Abstract

A simple two step wet etch approach to fabricate nanowires (NWs) with a tapered source/drain (S/D) architecture is presented. Based on the unique NW architecture, gate-all-around junctionless NW FETs with sub-15-nm channel length (L_CH), NW height (H_NW), and NW width (W_NW) were realized. Despite having a large equivalent oxide thickness of ∼ 4.5 nm, high extrinsic transconductance (_m,ext) of 820 μSμm was achieved at V_D of 0.5 V. Due to the unique tapered S/D structure, the device realized in this paper achieved S/D series resistance (R_SD) of 275 Ωμ m, which is one of the lowest among the reported 3-D InGaAs MOSFETs.
