  • Patent number: 8530121
    Abstract: 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 (?t) such that a sub-pixel shift of the exposed target pattern occurs in the second direction.

  • Publication number: 20120295185
    Abstract: A hologram reticle and method of patterning a target. A layout pattern for an image to be transferred to a target is converted into a holographic representation of the image. A hologram reticle is manufactured that includes the holographic representation. The hologram reticle is then used to pattern the target. Three-dimensional patterns may be formed in a photoresist layer of the target in a single patterning step. These three-dimensional patterns may be filled to form three-dimensional structures or else used in a multi-surface imaging composition. The holographic representation of the image may also be transferred to a top photoresist layer of a top surface imaging (TSI) semiconductor device, either directly or using the hologram reticle. The top photoresist layer may then be used to pattern an underlying photoresist layer with the image. The lower photoresist layer is used to pattern a material layer of the device.
