Abstract:
A method of forming stacked vertical field effect devices is provided. The method includes forming a layer stack on a substrate, wherein the layer stack includes a first spacer layer on the substrate, a first protective liner on the first spacer layer, a first gap layer on the first protective liner, a second protective liner on the first gap layer, a second spacer layer on the second protective liner, a sacrificial layer on the second spacer layer, a third spacer layer on the sacrificial layer, a third protective liner on the third spacer layer, a second gap layer on the third protective liner, a fourth protective liner on the second gap layer, and a fourth spacer layer on the fourth protective liner. The method further includes forming channels through the layer stack, a liner layer on the sidewalls of the channels, and a vertical pillar in the channels.

Claim (Index 17):
The stacked fin field effect device of  claim 16 , further comprising a lower gate structure on at least a portion of the sidewall of the lower vertical device segment, and an upper gate structure on at least a portion of the sidewall of the upper vertical device segment.
