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 gate dielectric layer, a work function layer, and a conductive filling over the work function layer. The semiconductor device structure also includes a dielectric layer covering the fin structure. The dielectric layer is in direct contact with the conductive filling.
