Abstract:
A method of forming high-k metal gates (HKMGs) includes removing a dummy gate structure formed over a first fin and a second fin to form a trench that exposes portions of the first fin and the second fin, forming a high-k dielectric layer over the exposed portions of the first fin and the second fin, forming a capping layer over the high-k dielectric layer, forming a hard mask layer over the capping layer, such that the hard mask layer fills the trench completely, forming an isolation feature in the hard mask layer between the first fin and the second fin, the isolation feature having sidewalls that extend through the capping layer, removing the hard mask layer to expose the capping layer and the sidewalls of the isolation feature, and forming a conductive electrode over the capping layer and along the sidewalls of the isolation feature.

Claim (Index 16):
The method of  claim 9 , wherein forming the hard mask layer includes depositing an oxide-based material over the high-k dielectric layer.
