Claim 14:
15. A nanosheet semiconductor device comprising:
a channel nanosheet stack comprising: a plurality of channel nanosheets each connected to a source and connected to a drain;
an internal gate surrounding the plurality of channel nanosheets;
a first ferroelectric region directly upon an upper surface of the internal gate;
a second ferroelectric region directly upon a sidewall of the internal gate; and
a dielectric spacer directly upon the sidewall of the internal gate and aligned with the second ferroelectric region, wherein a sidewall of the dielectric spacer is directly connected to a sidewall of the first ferroelectric region, and wherein a bottom surface of the dielectric spacer is directly connected to a top surface of the second ferroelectric region.
