Abstract
A device includes a base layer structure including a first region and a second region; a first bottom gate material in a plurality of first-type doped regions in the first and second regions; a second bottom gate material in a second-type doped regions in the first and second regions; first nanosheet gate-all-round device structures on the first bottom gate material; and second nanosheet gate-all-round device structures on the second bottom gate material, wherein the first bottom gate material is located over the second nanosheet gate-all-around device structures in the second-type doped regions of the first and second regions, wherein the second bottom gate material extends, in boundary regions between the first-type and second-type doped regions, on the base layer structure from the second nanosheet gate-all-around devices structures toward the first gate-all-round device structures.
