    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.

    摘要: Disclosed are methods for manufacturing semiconductor devices and the devices thus obtained. In one embodiment, the method comprises obtaining a semiconductor substrate comprising a germanium region doped with n-type dopants at a first doping level and forming an interfacial silicon layer overlying the germanium region, where the interfacial silicon layer is doped with n-type dopants at a second doping level and has a thickness higher than a critical thickness of silicon on germanium, such that the interfacial layer is at least partially relaxed. The method further includes forming over the interfacial silicon layer a layer of material having an electrical resistivity smaller than 1×10−2 Ωcm, thereby forming an electrical contact between the germanium region and the layer of material, wherein the electrical contact has a specific contact resistivity below 10−4 Ωcm2.
