Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 9:
10. A semiconductor apparatus comprised of
a substrate having a thin gate oxide nanosheet device and thick gate oxide nanosheet device located thereon;
wherein the thin gate oxide nanosheet device is comprised of:
a plurality of first nanosheet layers, wherein each of the plurality of first nanosheet layers have a varying thickness along the horizonal axis of the plurality of first nanosheet layers, wherein a thinnest section of each of the plurality of first nanosheet layers is located at the center of each of the plurality of first nanosheet layers;
a first spacer layer in contact with each of the first plurality of nanosheet layers;
a first oxide layer located above and below each of the first plurality of nanosheet layers, wherein the first oxide layer is in direct contact with each of the plurality of first nanosheet layers;

wherein the thick gate oxide nanosheet device is comprised of:
a plurality of second nanosheet layers, wherein each of the plurality of second nanosheets has a constant thickness;

wherein the constant thickness of each of the plurality of second nanosheets is greater than the thinnest section of each of the plurality of first nanosheet layers.
