Abstract
A semiconductor structure is provided. The semiconductor structure includes a first set of nanostructures that are stacked vertically and spaced apart from one another and formed in a first well, a source/drain feature adjoining the first set of nanostructures, a first top gate electrode layer above a topmost nanostructure in the first set of nanostructures, and an inner gate electrode layer sandwiched between the nanostructures. A first dimension of the inner gate electrode layer in a first direction is greater than a second dimension of the first top gate electrode layer in the first direction.
