    摘要: A cobalt silicide process having a titanium-rich/titanium nitride capping layer to improve junction leakage is described. Semiconductor device structures to be silicided are formed in and on a semiconductor substrate. A cobalt layer is deposited overlying the semiconductor device structures. A titanium-rich/titanium nitride capping layer is deposited overlying the cobalt layer. Thereafter, a cobalt silicide layer is formed on the semiconductor device structures. The titanium-rich/titanium nitride capping layer and an unreacted portion of the cobalt layer are removed to complete fabrication of the integrated circuit device.

    摘要: A method of fabricating a node contact opening is described. A dielectric layer is formed on a substrate. A first conductive layer is formed on the dielectric layer. The first conductive layer is etched to form a trapezoidally cross-sectioned opening exposing a portion of the dielectric layer. The dielectric layer exposed by the trapezoidally cross-sectioned opening is etched to form a node contact opening in the dielectric layer exposing a part the substrate. A second conductive layer is formed to fill the node contact opening and in contact with the conductive layer.

    摘要: A method for forming multiple layer metallurgy, spin-on-glass multilayer metallurgy for a one micrometer or less feature size integrated circuit with substantially free field inversion, that is the positive charge between the first via layer and the SOG is described. A semiconductor substrate having a pattern of field effect device source/drain regions therein with a pattern of gate dielectric and gate electrode structures associated therewith and a pattern of field isolation structures at least partially within semiconductor substrate electrically separating certain of these source/drain regions from one another are provided. A passivation layer is formed over the surfaces of said patterns. Then the multilayer metallurgy is formed thereover by opening a pattern of openings through the passivation layer to at least some of the source/drain regions, depositing and patterning a first metallurgy layer in contact with the pattern of openings, forming a first via dielectric layer over the pattern of first metallurgy layer, exposing the first silicon oxide via dielectric layer to a nitrogen plasma, forming a spin-on-glass layer over the via dielectric layer and curing the layer, forming a second via dielectric layer over the spin-on-glass layer, forming a pattern of openings in the second via layer, the spin-on-glass layer, and the first via layer, and depositing and patterning a second metallurgy layer through the openings to make electrical contact with the first metallurgy layer.

    摘要: This invention relates to a method of fabrication used for semiconductor integrated circuit devices, and more specifically, to improve the photolithography processing window of a multi-layered dual damascene process by using a dielectric anti-reflective coating, DARC, comprised of multiple layers of silicon oxynitride, SiON, with varying k, dielectric constant values and thickness, to reduce reflectivity and improve light absorption. By varying both the thickness and the dielectric constant of the layers, the optical properties of light absorption, refractive indices, and light reflection are optimized.
