Balanced Drive Currents in 10–20 nm Diameter Nanowire All-III-V CMOS on Si

Jönsson, Adam LU ; Svensson, Johannes LU and Wernersson, Lars-Erik LU (2019) 64th IEEE International Electron Devices Meeting p.1-39
Abstract
We use a self-aligned, gate-last process providing n-type (InAs) and p-type (GaSb) MOSFET co-integration with a common gate-stack and demonstrate balanced drive current capability at about 100 μA/μm . By utilizing HSQ-spacers, control of gate-alignment allows to fabricate both n- and p-type devices based on the same type of vertical heterostructure InAs/GaSb nanowire with short gate-lengths down to 60 nm. Refined digital etch techniques, compatible with both sensitive antimonide structures and InAs, enable down to 16 nm diameter GaSb channel regions and 10 nm InAs channels. Balanced performance is showcased for both n- and p-type MOSFETs with Ion=156 μA/μm , at Ioff=100 nA/μm , and 98μA/μm , at |VDS|=0.5 , respectively.
