    摘要: The present invention relates to a composition comprising a photoresist polymer and a fluoropolymer. In one embodiment, the fluoropolymer comprises a first monomer having a pendant group selected from alicyclic bis-hexafluoroisopropanol and aryl bis-hexafluoroisopropanol and preferably a second monomer selected from fluorinated styrene and fluorinated vinyl ether. The invention composition has improved receding contact angles with high refractive index hydrocarbon fluids used in immersion lithography and, thereby, provides improved performance in immersion lithography.

    摘要: Methods are disclosed for forming topographical features. In one method, a pre-patterned structure is provided which comprises i) a support member having a surface and ii) an element for topographically guiding segregation of a polymer mixture including a first polymer and a second polymer, the element comprising a feature having a sidewall adjoined to the surface. The polymer mixture is disposed on the pre-patterned structure, wherein the disposed polymer mixture has contact with the sidewall and the surface. The first polymer and the second polymer are segregated in a plane parallel to the surface, thereby forming a segregated structure comprising a first polymer domain and a second polymer domain. The first polymer domain and/or the second polymer domain are lithographically patterned, thereby forming topographical features comprising at least one of i) a first feature comprising a lithographically patterned first polymer domain and ii) a second feature comprising a lithographically patterned second polymer domain.

    摘要: A layered structure comprising a self-assembled material is formed by a method that includes forming a photochemically, thermally and/or chemically treated patterned photoresist layer disposed on a first surface of a substrate. The treated patterned photoresist layer comprises a non-crosslinked treated photoresist. An orientation control material is cast on the treated patterned photoresist layer, forming a layer containing orientation control material bound to a second surface of the substrate. The treated photoresist and, optionally, any non-bound orientation control material are removed by a development process, resulting in a pre-pattern for self-assembly. A material capable of self-assembly is cast on the pre-pattern. The casted material is allowed to self-assemble with optional heating and/or annealing to produce the layered structure.

    摘要: A method and a computer system for designing an optical photomask for forming a prepattern opening in a photoresist layer on a substrate wherein the photoresist layer and the prepattern opening are coated with a self-assembly material that undergoes directed self-assembly to form a directed self-assembly pattern. The methods includes: generating a mask design shape from a target design shape; generating a sub-resolution assist feature design shape based on the mask design shape; using a computer to generate a prepattern shape based on the sub-resolution assist feature design shape; and using a computer to evaluate if a directed self-assembly pattern of the self-assembly material based on the prepattern shape is within specified ranges of dimensional and positional targets of the target design shape on the substrate.
