    摘要: Trench isolation methods for integrated circuits may reduce irregularities in the formation of an isolation layer through use of a high selectivity chemical-mechanical polishing (CMP) operation. In particular, a substrate surface is etched to form a trench. An insulation layer is then formed on the substrate surface and in the trench. The insulation layer is chemical-mechanical polished using a slurry that includes a CeO2 group abrasive to form an isolation layer in the trench. The CMP selectivity ratio of a slurry that includes a CeO2 group abrasive may be sufficient to allow the substrate surface to be used as a CMP stop. As a result, a more consistent level of polishing may be maintained over the substrate surface, which may result in a more uniform thickness in the isolation layer.

    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.
