The pattern is subsequently transferred through the hard mask layer and the carbon-based template layer with high selectivity to gate spacers to form self-aligned cavities within the carbon-based template layer. Contact structures are formed within the carbon-based template layer by a damascene method. The hard mask layer and the carbon-based template layer are subsequently removed selective to the contact structures.

  • Patent number: 7833853
    Abstract: Provided is a method of semiconductor fabrication including process steps allowing for defining and/or modifying a gate structure height during the fabrication process. The gate structure height may be modified (e.g., decreased) at one or more stages during the fabrication by etching a portion of a polysilicon layer included in the gate structure. The method includes forming a coating layer on the substrate and overlying the gate structure. The coating layer is etched back to expose a portion of the gate structure. The gate structure (e.g., polysilicon) is etched back to decrease the height of the gate structure.

  • Patent number: 7723221
    Abstract: A stacked film patterning method is provided which is capable of reliably removing residual substances remaining after etching of a metal film, improving etching uniformity of a silicon film, and preventing an occurrence of etching residues. A micro-crystal film and a chromium film are sequentially formed on an insulating film serving as a front-end film and the chromium film is etched to be patterned by using a resist as a mask. Next, a micro-crystal silicon film on which the residual substances exist is exposed to plasma of a mixed gas including chlorine gas and oxygen gas to selectively etch the residual substances on a surface of the micro-crystal silicon film. After that, the micro-crystal silicon film is dry etched.
