    摘要: A process for forming a storage capacitor for a semiconductor assembly, by forming a first storage electrode having a top surface consisting of titanium nitride; forming a barrier layer directly on the titanium nitride, the barrier layer (a material containing any one of amorphous silicon, tantalum, titanium, or strontium) being of sufficient thickness to substantially limit the oxidation of the titanium nitride when the semiconductor assembly is subjected to an oxidizing agent (either an oxidizing agent or an nitridizing agent); converting a portion of the barrier layer to a dielectric compound; depositing a storage cell dielectric directly on the dielectric compound, the storage cell dielectric being of the same chemical makeup as the dielectric compound and thereby using the dielectric compound as a nucleation surface; and forming a second capacitor electrode on the storage cell dielectric.

    摘要: An exemplary implementation of the present invention includes a capacitor for a dynamic random access memory cell having a first plate; a second plate; and a dielectric layer interposed between said first and second plates, with the dielectric layer being dominated by electrode-limited conduction, which includes tantalum pentoxide and silicon nitride, or a combination of the two. In a preferred implementation, one of the two capacitor plates is formed from a silicon-germanium layer, the second plate is formed from a metal and the dielectric layer is formed from tantalum pentoxide.

    摘要: A method for conditioning a dielectric material on a semiconductor substrate structure during a semiconductor fabrication process, comprising the steps of: irradiating the dielectric material using ultraviolet light irradiation while in a ambient exhibiting the properties of self-limiting oxidation, during a first annealing period; following the first annealing period by exposing the dielectric material to an oxygen ambient during a second annealing period. This method may be applied to the conditioning of a capacitor dielectric on a capacitor structure, or to the conditioning of a field effect transistor gate dielectric on a field effect transistor gate structure or to the conditioning of insulative spacers about the sidewalls of a field effect transistor gate structure.

    摘要: An intermediate metal plug is used to raise the platform to which contact is to be made. In the illustrated process, a partial bit line plug is formed adjacent a stacked capacitor, and an interlevel dielectric formed over the capacitor. The bit line contact is completed by extending a via from the bit line, formed above the interlevel dielectric, down to the level of the intermediate plug, and the via is filled with metal. The height of the via to be filled is thus reduced by the height of the intermediate plug. In one embodiment, the intermediate plug is slightly shorter than an adjacent container-shaped capacitor. In another embodiment, the intermediate plug is about as high as an adjacent stud capacitor.
