Abstract:
Structures and formation methods of a semiconductor device structure are provided. The semiconductor device structure includes a fin structure over a semiconductor substrate and a gate stack covering a portion of the fin structure. The gate stack includes a work function layer and a gate dielectric layer. The semiconductor device structure also includes an isolation element over the semiconductor substrate and adjacent to the gate stack. The isolation element is in direct contact with the work function layer and the gate dielectric layer, and a lower width of the isolation element is greater than an upper width of the isolation element

Claim (Index 1):
A method comprising:\n forming a first fin structure and a second fin structure over a semiconductor substrate; forming an isolation feature between the first fin structure and the second fin structure; forming a gate dielectric layer extending over the isolation feature, the first fin structure, and the second fin structure; forming a metal containing barrier layer on the gate dielectric layer; forming an opening in the gate dielectric layer and in the metal containing barrier layer, the opening exposing the isolation feature; forming an isolation element in the opening; and forming a first gate electrode in contact with a first sidewall of the isolation element and a second gate electrode in contact with a second opposite sidewall of the isolation element, the isolation element electrically isolating the first gate electrode and the second gate electrode.
