  • Publication number: 20230375941
    Abstract: A method of generating a layout pattern includes determining a first energy density indirectly exposed to a first feature of one or more features of a layout pattern on an energy-sensitive material when the one or more features of the layout pattern on the energy-sensitive material are directly exposed by a charged particle beam. The method also includes adjusting a second energy density exposed the first feature when the first feature is directly exposed by the charged particle beam. A total energy density of the first feature that comprises a sum of the first energy density from the indirect exposure and the second energy density from the direct exposure is maintained at about a threshold energy level to fully expose the first feature in the energy-sensitive material.

  • Publication number: 20230273524
    Abstract: An electron beam lithography system and an electron beam lithography process are disclosed herein for improving throughput. An exemplary method for increasing throughput achieved by an electron beam lithography system includes receiving an integrated circuit (IC) design layout that includes a target pattern, wherein the electron beam lithography system implements a first exposure dose to form the target pattern on a workpiece based on the IC design layout. The method further includes inserting a dummy pattern into the IC design layout to increase a pattern density of the IC design layout to greater than or equal to a threshold pattern density, thereby generating a modified IC design layout. The electron beam lithography system implements a second exposure dose that is less than the first exposure dose to form the target pattern on the workpiece based on the modified IC design layout.
