Abstract
A device includes a first vertical stack of first nanostructures formed over a substrate, a second vertical stack of second nanostructures adjacent to the first vertical stack, and a first gate structure adjacent the first nanostructures. The first gate structure includes a first gate portion between the first nanostructures, and a second gate portion extending from a first sidewall of the first gate portion to a second sidewall of the first gate portion. The second sidewall is between the first sidewall and the substrate, and is a different material than the first gate portion. A second gate structure is adjacent the second nanostructures, and a second wall structure is between the second gate portion and the second gate structure.
