    摘要: A method for making a transistor 20 that includes using a transition metal nitride layer 200 and/or a SOG layer 220 to protect the source/drain regions 60 from silicidation during the silicidation of the gate electrode 90. The SOG layer 210 is planarized to expose the transition metal nitride layer 200 or the gate electrode 93 before the gate silicidation process. If a transition metal nitride layer 200 is used, then it is removed from the top of the gate electrode 93 before the full silicidation of the gate electrode 90.

    摘要: A method of forming a fully silicided semiconductor device with independent gate and source/drain doping and related device. At least some of the illustrative embodiments are methods comprising forming a gate stack over a substrate (the gate stack comprising a polysilicon layer and a blocking layer), and performing an ion implantation into an active region of the substrate adjacent to the gate stack (the blocking layer substantially blocks the ion implantation from the polysilicon layer).
