    Abstract: The present invention provides, in one embodiment, a process for forming a dual work function metal gate semiconductor device (100). The process includes providing a semiconductor substrate (105) having a gate dielectric layer (110) thereon and a metal layer (205) on the gate dielectric layer. A work function of the metal layer is matched to a conduction band or a valence band of the semiconductor substrate. The process also includes forming a conductive barrier layer (210) on a portion (215) of the metal layer and a material layer (305) on the metal layer. The metal layer and the material layer are annealed to form a metal alloy layer (405) to thereby match a work function of the metal alloy layer to another of the conduction band or the valence band of the substrate. Other embodiments of the invention include a dual work function metal gate semiconductor device (900) and an integrated circuit (1000).

    Abstract: Semiconductor devices and fabrication methods are provided, in which metal transistor gates are provided for MOS transistors. Metal boride is formed above a gate dielectric to create PMOS gate structures and metal nitride is formed over a gate dielectric to provide NMOS gate structures. The metal portions of the gate structures are formed from an initial starting material that is either a metal boride or a metal nitride, after which the starting material is provided with boron or nitrogen in one of the PMOS and NMOS regions through implantation, diffusion, or other techniques, either before or after formation of the conductive upper material, and before or after gate patterning. The change in the boron or nitrogen content of the starting material provides adjustment of the material work function, thereby tuning the threshold voltage of the resulting PMOS or NMOS transistors.

    Abstract: The present invention facilitates semiconductor fabrication by maintaining shape and density of an etch stop layer (206) during trench fill operations. The shape and density of the etch stop layer (206) is maintained by forming a protective alloy liner layer (310) on the etch stop layer (206) prior to trench fill operations. The protective alloy liner (310) is comprised of an alloy that is resistant to materials employed in the trench fill operations. As a result, clipping and/or damage to the etch stop layer (206) is mitigated thereby facilitating a subsequent planarization process that employs the etch stop layer (206). Additionally, selection of thickness and composition (1706) of the formed protective alloy (310) yields a stress amount and type (1704) that is applied to channel regions of unformed transistor devices, ultimately providing for an improvement in channel mobility.

    Abstract: Forming metal gate transistors that have different work functions is disclosed. In one example, a first metal is added to a first region of polysilicon overlying a dielectric that is on a substrate, and a second metal is added to a second region of the polysilicon. A third metal is formed over the first and second regions and a silicidation process if performed to form a first alloy in the first region and a second alloy in the second region. First and second segregated regions are also established adjacent to the dielectric in the first and second regions, respectively. The first and second metals serve to shift or adjust respective values of first and second work functions in the first and second regions.

    Abstract: The present invention facilitates semiconductor fabrication by providing methods of fabrication that selectively form high-k dielectric layers within NMOS regions. An oxide layer is formed in core and I/O regions of a semiconductor device (506). The oxide layer is removed (508) from the core region of the device. A high-k dielectric layer is formed (510) over the core and I/O regions. Then, the high-k dielectric layer is removed (512) from PMOS regions of the core and I/O regions. A silicon nitride layer is grown (516) within PMOS regions of the core and I/O regions by a low temperature thermal process. Subsequently, an oxidation process is performed (518) that oxidizes the silicon nitride into silicon oxynitride.
