  • DATA GENERATION APPARATUS, DATA GENERATION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
    Publication number: 20240105420
    Abstract: A data generation apparatus of one embodiment includes a processing unit, an evaluation unit, and a conversion unit. The processing unit designs, through optical proximity correction based on a target pattern formed on a substrate using the photomask, a mask pattern corresponding to the target pattern and including a plurality of rectangular regions. The evaluation unit evaluates the mask pattern using a cost function having, as a parameter, a jog length indicating a length of each of the rectangular regions included in the mask pattern in a first direction. The conversion unit converts mask pattern data indicating the mask pattern with an evaluation that meets a predetermined condition to drawing data corresponding to a variable shaped beam drawing process.
