    摘要: A pattern generator includes a minor array plate having a mirror, at least one electrode plate disposed over the minor array plate, a lens let disposed over the minor, and at least one insulator layer sandwiched between the mirror array plate and the electrode plate. The electrode plate includes a first conducting layer and a second conducting layer. The lens let has a non-straight sidewall formed in the electrode plate. The pattern generator further includes at least one insulator sandwiched between two electrode plates. The non-straight sidewall can be a U-shaped sidewall or an L-shaped sidewall.

    摘要: A method for fabricating a semiconductor device is disclosed. An exemplary method includes forming a first structure in a first layer by a first exposure and determining placement information of the first structure. The method further includes forming a second structure in a second layer overlying the first layer by a second exposure and determining placement information of the second structure. The method further includes forming a third structure including first and second substructures in a third layer overlying the second layer by a third exposure. Forming the third structure includes independently aligning the first substructure to the first structure and independently aligning the second substructure to the second structure.

    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: A method for fabricating a semiconductor device is disclosed. An exemplary method includes receiving an integrated circuit (IC) layout design including a target pattern on a grid. The method further includes receiving a multiple-grid structure. The multiple-grid structure includes a number of exposure grid segments offset one from the other by an offset amount in a first direction. The method further includes performing a multiple-grid exposure to expose the target pattern on a substrate and thereby form a circuit feature pattern on the substrate. Performing the multiple-grid exposure includes scanning the substrate with the multiple-grid structure in a second direction such that a sub-pixel shift of the exposed target pattern occurs in the first direction, and using a delta time (Δt) such that a sub-pixel shift of the exposed target pattern occurs in the second direction.
