Abstract:
The present invention provides a method for forming a semiconductor structure. The method including: Firstly, a substrate is provided, a first region and a second region are defined thereon, next, a gate dielectric layer and a work function metal layer are sequentially formed on the substrate within the first region and within the second region. Afterwards, a dielectric layer is formed on the work function metal layer within the second region, a hydrogen gas treatment is then performed on the substrate, and the work function metal layer is removed within the first region.

Claim (Index 4):
The method of  claim 1 , wherein the hydrogen gas treatment is performed with a nitrogen gas treatment simultaneously.
