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 7):
The method of  claim 1 , further comprising forming at least two trenches within the first region and within the second region respectively, wherein the gate dielectric layer and the work function metal layer are disposed in the trenches.
