Abstract: A device includes a gate electrode and a gate dielectric surrounding the gate electrode. The gate electrode surrounds a nanostructure. The nanostructure includes stacked nanosheets. The gate dielectric is formed by a high-k (HK) material. The HK material covers sidewalls of the gate electrode in a direction aligned to adjacent devices.
