    摘要: A semiconductor device containing an interconnection structure having a reduced interwiring spacing is produced by a modified dual damascene process. In one embodiment, an opening for a via is initially formed in a second insulative layer above a first insulative layer with an etch stop layer therebetween. A larger opening for a trench is then formed in the second insulative layer while simultaneously extending the via opening through the etch stop layer and first insulative layer. The trench and via are then simultaneously filled with conductive material.

    摘要: Methods of selectively forming metal silicides on a memory device are provided. The methods can include forming a mask layer over the memory device; forming a patterned resist over the mask layer; removing upper portions of the patterned resist; forming a patterned mask layer by removing portions of the mask layer that are not covered by the patterned resist; and forming metal silicides on the memory device by a chemical reaction of a metal layer formed on the memory device with portions of the memory device that are not covered by the patterned mask layer. By preventing silicidation of underlying silicon containing layers/components of the memory device that are covered by the patterned mask layer, the methods can selectively form the metal silicides on the desired portions of the memory device.

    摘要: A method for manufacturing a semiconductor device including selective conductive contacts includes the step of depositing a resist over first and second memory device components, each of the first and second components comprising junctions formed in the substrate and a gate formed on the substrate between the junctions. The resist is then removed from the second components to thereby form a resist opening above each of the second component control gates and junctions. The resist is then etched to thereby expose each of the first component control gates but not the substrate surrounding the first component control gates. Conductive contacts are then formed on the exposed first component control gates, and the second component control gates and junctions.
