    摘要: A silicidation process for a MOS transistor and a resulting transistor structure are described. The MOS transistor includes a silicon substrate, a gate dielectric layer, a silicon gate, a cap layer on the silicon gate, a spacer on the sidewalls of the silicon gate and the cap layer, and S/D regions in the substrate beside the silicon gate. The process includes forming a metal silicide layer on the S/D regions, utilizing plasma of a reactive gas to react a surface layer of the metal silicide layer into a passivation layer, removing the cap layer and then reacting the silicon gate into a fully silicided gate.

    摘要: A method of removing material layer is disclosed. First, a semiconductor substrate is fixed on a rotating platform, where a remnant material layer is included on the surface of the semiconductor substrate. Afterward, an etching process is carried out. In the etching process, the rotating platform is rotated, and an etching solution is sprayed from a center region and a side region of the rotating platform toward the semiconductor substrate until the material layer is removed. Since the semiconductor substrate is etched by the etching solution sprayed from both the center region and the side region of the rotating platform, the etching uniformity of the semiconductor substrate is improved.

    摘要: The invention provides a method for forming a metal silicide layer. The method comprises steps of providing a substrate and forming a nickel-noble metal layer over the substrate. A grain boundary sealing layer is formed on the nickel-noble metal layer and then an oxygen diffusion barrier layer is formed on the grain boundary sealing layer. Thereafter, a rapid thermal process is performed to transform a portion of the nickel-noble metal layer into a metal silicide layer. Finally, the oxygen diffusion barrier layer, the grain boundary sealing layer and the rest portion of the nickel-noble metal layer are removed.

A spacer is formed on sidewalls of the gate electrode. A source/drain is implanted into the substrate. A pre-amorphization implant (PAI) is performed to form an amorphized layer on the source/drain. A post-PAI annealing process is performed to repair defects formed during the PAI process. A metal silicide layer is then formed from the amorphized layer.
