Abstract
Semiconductor structures and methods for manufacturing the same are provided. The semiconductor structure includes a first well region and longitudinally oriented along a first direction and a second well region adjoining the first well region in a second direction. The semiconductor structure also includes a dielectric wall structure formed over a boundary between the first well region and the second well region and first channel structures vertically suspended over a first region of the first well region and laterally attached to a first sidewall surface of the dielectric wall structure. The semiconductor structure includes a first gate structure wrapping around the first channel structures and second channel structures vertically suspended over a second region of the first well region and a second gate structure wrapping around the second channel structures. In addition, the first channel structures is smaller than the second channel structures.
