    Abstract: The present disclosure provides a method of fabricating a semiconductor device with metal interconnections and a design of a tool for performing such a method. In one embodiment, a method of fabricating a semiconductor device, the method includes providing a semiconductor substrate, depositing a dielectric layer over the semiconductor substrate, forming at least one trench in the dielectric layer, and forming a metallization layer in the trench and over the dielectric layer. The method further includes performing a chemical mechanical polishing process to planarize the metallization layer and the dielectric layer, performing a surface treatment on the planarized dielectric layer to form a protection layer, cleaning the planarized metallization layer and the treated dielectric layer to remove residue from the chemical mechanical polishing process, and drying the cleaned metallization layer and dielectric layer in an inert gas environment.
