Abstract: A method of fabricating a cobalt silicide layer includes providing a substrate disposed in a chamber. A deposition process is performed to form a cobalt layer covering the substrate. The deposition process is performed when the temperature of the substrate is between 50° C. and 100° C., and the temperature of the chamber is between 300° C. and 350° C. After the deposition process, an annealing process is performed to transform the cobalt layer into a cobalt silicide layer. The annealing process is performed when the substrate is between 300° C. and 350° C., and the duration of the annealing process is between 50 seconds and 60 seconds.

Abstract: A method for manufacturing a semiconductor device with a cobalt silicide film is provided in the present invention. The method includes the steps of providing a silicon structure with an interlayer dielectric formed thereon, forming a contact hole in the interlayer dielectric to expose the silicon structure, depositing a cobalt film on the exposed silicon structure at a temperature between 300° C-400° C., wherein a cobalt protecting film is in-situ formed on the surface of the cobalt film, performing a rapid thermal process to transform the cobalt film into a cobalt silicide film, and removing untransformed cobalt film.
