    摘要: A method of data preparation in lithography processes is described. The method includes providing an integrated circuit (IC) layout design in a graphic database system (GDS) grid, converting the IC layout design GDS grid to a first exposure grid, applying a non-directional dither technique to the first exposure, coincident with applying dithering to the first expose grid, applying a grid shift to the first exposure grid to generate a grid-shifted exposure grid and applying a dither to the grid-shifted exposure grid, and adding the first exposure grid (after receiving dithering) to the grid-shifted exposure grid (after receiving dithering) to generate a second exposure grid.

    摘要: Provided are a high resolution lithography system and method. In one example, a method for producing a pattern on a substrate includes separating the pattern into at least a first sub-pattern containing lines oriented in a first direction and a second sub-pattern containing lines oriented in a second direction. Lines oriented in the first direction are created on a first layer of photosensitive material on the substrate using a first standing wave interference pattern. A portion of the created lines are trimmed to create the first sub-pattern. A second layer of photosensitive material is applied to the substrate after creating the first sub-pattern. Lines oriented in the second direction are created on the second layer using a second standing wave interference pattern. A portion of the created lines are trimmed to create the second sub-pattern.
