摘要:
The invention provides a method for manufacturing a semiconductor device that comprises placing a metallic gate layer over a gate dielectric layer where the metallic gate layer has a crystallographic orientation, and re-orienting the crystallographic orientation of the metallic gate layer by subjecting the metallic gate layer to a hydrogen anneal.
