    摘要: A method for fabricating a MOS transistor using a selective silicide process wherein a gate insulating layer and a gate polysilicon layer are sequentially formed on a silicon substrate, and a gate spacer is formed on a side wall of the gate insulating layer and the gate polysilicon layer. Impurity ions are implanted and diffused using the gate spacer and the gate polysilicon layer as a mask layer to form a source/drain region in the substrate. An etching blocking layer is formed to cover the source/drain region, the gate spacer, and the gate polysilicon layer, and then, a dielectric layer to cover the etching blocking layer is formed. The dielectric layer is planarized, and the etching blocking layer on the gate polysilicon layer is exposed. The exposed etching blocking layer and a part of the gate spacer are etched, and a top surface and a top side of the gate polysilicon layer are exposed. A silicide layer is formed over the exposed part of the gate polysilicon layer.

    摘要: A method of forming fine pitch hardmask patterns includes forming a hardmask layer on a substrate and forming a plurality of first mask patterns on the hardmask layer. A buffer layer is formed on the plurality of first mask patterns, and has an upper surface defining recesses between adjacent first mask patterns. Second mask patterns are formed within the recesses formed in the upper surface of the buffer layer. The buffer layer is partially removed to expose upper surfaces of the plurality of first mask patterns, and the buffer layer is then partially removed using the first mask patterns and the second mask patterns as an etch mask to expose the hardmask layer between the first mask pattern and the second mask pattern. Using the first mask patterns and the second mask patterns as an etch mask, the hardmask layer is etched to form hardmask patterns.
