Abstract:
A method of forming a vertical transport field effect transistors with uniform bottom spacer thickness, including, forming a plurality of vertical fins on a substrate, forming a protective liner layer on the plurality of vertical fins, forming a sacrificial liner on the protective liner layer, forming a spacer liner on a portion of the sacrificial liner, wherein at least a top surface of the sacrificial liner on each of the vertical fins is exposed, converting the exposed portion of the sacrificial liner on each of the vertical fins to a conversion cap, and removing the conversion cap from each of the vertical fins to expose an upper portion of each vertical fin.

Claim (Index 16):
A vertical transport field effect transistor with uniform bottom spacer thickness, comprising:\n a plurality of vertical fins on a substrate; a plurality of protective liner segments on the substrate; a conversion segment on each of the plurality of protective liner segments, wherein the plurality of conversion segments each covers one of the protective liner segments on a sidewall of at least one of the plurality of vertical fins to a predetermined height; a gate dielectric layer on the conversion segments; and a top source/drain on each of the plurality of vertical fins.
