    摘要: Sub-resolution assist features for non-collinear features are described for use in photolithography. A photolithography mask with elongated features is synthesized. An end-to-end gap between two features if found for which the ends of the two features facing the gap are linearly offset from one another. A sub-resolution assist feature is applied to the end-to-end gap between the elongated features, and the synthesized photolithography mask is modified to include the sub-resolution assist feature.

    摘要: A method of forming a pattern on a wafer is provided. The method includes applying a photoresist on the wafer and exposing the wafer to define a first pattern on the photoresist. The method also includes exposing the wafer to define a second pattern on the photoresist, wherein each of the first and second patterns comprises unexposed portions of the photoresist and developing the wafer to form the first and second patterns on the photoresist, wherein the first and second patterns are formed by removing the unexposed portions of the photoresist.

    摘要: In one embodiment, a mask for use in semiconductor processing comprises a first region formed from a first material that is primarily opaque, a second region formed from a second material that is primarily transmissive, and a third region in which at least a portion of the second material is removed to generate a phase shift in radiation applied to the mask.

    摘要: A semiconductor wafer may be coated with an imageable anti-reflective coating. As a result, the coating may be removed using the same techniques used to remove overlying photoresists. This may overcome the difficulty of etching anti-reflective coatings using standard etches because of their poor selectivity to photoresist and the resulting propensity to cause integrated circuit defects arising from anti-reflective coating remnants.

    摘要: The present invention relates to the reduction of critical dimensions and the reduction of feature sizes in manufacturing integrated circuits. Specifically, the method controls photoresist flow rates to develop critical dimensions beyond the resolution limits of the photoresist material used, and the limits of lithographic tool sets. The post exposure and developed resist pattern is exposed to a solvent prior to a bake or reflow process. Exposure to the solvent lowers the molecular weight of the resist material, modifying the resist material's reflow rate. The post-exposure resist is then easier to control during a subsequent reflow process to reduce the hole or line size of the patterned resist.
