Abstract
A semiconductor device including a substrate; a continuous buried oxide layer (BOX) formed on the substrate; and a plurality of nanosheet gate-all-round (GAA) device structures on the BOX, wherein a first plurality of stacked gates of the nanosheet GAA device structures are disposed in a logic portion of the substrate and have a first nanosheet width, wherein a second plurality of stacked gates of the nanosheet GAA device structures are disposed in a high density region of the substrate and have a second nanosheet width less than the first nanosheet width, wherein the nanosheet GAA device structures are disposed directly on the continuous buried oxide layer, and wherein a bottom layer of the nanosheet GAA device structures is a bottom gate formed directly on the BOX.
