    摘要: A method for manufacturing CMOS devices with fully silicided (FUSI) gates is described. A metallic gate electrode of an NMOS transistor and a metallic gate electrode of a pMOS transistor have a different work function. The work function of each transistor type is determined by selecting a thickness of a corresponding semiconductor gate electrode and a thermal budget of a first thermal step such that, during silicidation, different silicide phases are obtained on the nMOS and the pMOS transistors. The work function of each type of transistor can be adjusted by selectively doping the semiconductor material prior to the formation of the silicide.

    摘要: Methods of manufacturing metal-insulator-metal capacitor structures, and the metal-insulator-metal capacitor structures obtained, are disclosed. In one embodiment, a method includes providing a substrate, forming on the substrate a first metal layer comprising a first metal, and using atomic layer deposition with an H2O oxidant to deposit on the first metal layer a protective layer comprising TiO2. The method further includes using atomic layer deposition with an O3 oxidant to deposit on the protective layer a dielectric layer of a dielectric material, and forming on the dielectric layer a second metal layer comprising a second metal. In another embodiment, a metal-insulator-metal capacitor includes a bottom electrode comprising a first metal, a protective layer deposited on the bottom electrode and comprising TiO2, a dielectric layer deposited on the protective layer and comprising a dielectric material, and a top electrode formed on the dielectric layer and comprising a second metal.

    摘要: A method is described for forming an at least partially silicided contact. In one embodiment, a hardmask is deposited over a contact. A coating of sacrificial material is then provided on top of the hardmask. The sacrificial material coating is etched back until the top of the contact is exposed. The contact is then opened, the sacrificial material is removed, and a silicidation of the contact is performed.
