We report the first demonstration of InAs FinFETs with fin width W<sub>fin</sub> in the range 25-35 nm, formed by inductively coupled plasma etching. The channel comprises defect-free, lattice-matched InAs with fin height H<sub>fin</sub> = 20 nm controlled by the use of an etch stop layer incorporated into the device heterostructure. For a gate length L<sub>g</sub> = 1 μm, peak transconductance gm,peak = 1430 μS/μm is measured at V<sub>d</sub> = 0.5 V demonstrating that electron transport in InAs fins can match planar devices.
