Patent number: 11914305Abstract: In embodiments of a digital lithography system, physical design data prepared at a data prep server in a hierarchical data structure. A leaf node comprises a repeater nod, comprising a bitmap image and a plurality of locations at which the bitmap appears in a physical design. At an EYE server, a repeater node bitmap is adjusted based upon, for example, spatial light modulator rotational adjustment and substrate distortion. The adjusted repeater node and the plurality of locations in which the adjusted repeater appears is compared to the repeater of the data prep server and its plurality of locations. In further embodiments, a rasterizer generates a checksum of bitmap to be printed to a substrate, from the EYE server bitmap. The checksum is compared to a checksum of the EYE server bitmap.Type: GrantFiled: February 18, 2020Date of Patent: February 27, 2024Assignee: Applied Materials, Inc.Inventors: Chung-Shin Kang, Jun Yang, Hongbin Ji
