  • Patent number: 6709879
    Abstract: A method for inspecting a pattern defect process is disclosed, in which a layer is formed to raise a signal-to-noise ratio on the substrate. This invention also provides a method for inspecting a pattern defect process. First of all, a substrate is provided. Then, a device profile is formed on the substrate, wherein the device profile comprises a defect portion. Then, a layer is formed on the device profile and the substrate, wherein the layer has an etch selectivity different from the etch selectivity of the device profile. Next, the layer is removed partially to stop on the device profile and to cause a revere mask. Then, the device profile is etched on the substrate by using the revere mask as a mask. Finally, the revere mask is removed.

  • Patent number: 6291279
    Abstract: A semiconductor wafer has a substrate, a first region in the substrate that is used for a logic circuit, and a second region in the substrate that is used for a memory cell. A first gate in the first region and a second gate in the second region are simultaneously formed on the substrate. The first gate and the second gate both include a gate dielectric layer, a polysilicon layer, a tungsten silicide layer and a cap layer, in ascending order. The cap layer and the tungsten silicide layer are then removed from the first gate. A spacer around each gate is then formed. This completes the second type MOS transistor in the memory cell of DRAM. A titanium silicide layer on the surface of the substrate adjacent to the first gate and on the surface of the polysilicon layer of the first gate is formed so as to complete the formation of the first type MOS transistor.
