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 19):
The method of  claim 18 , wherein forming the first gate electrode and the second gate electrode comprises:\n forming a work function layer over the barrier layer and the modified isolation element; depositing a blocking layer over the work function layer; forming a metal filling layer over the blocking layer; and planarizing top surfaces of the metal filling layer, the blocking layer, the work function layer, and the modified isolation element, thereby forming the first gate electrode over the first fin structure and the second gate electrode over the second fin structure.
