Classification: CPC G  H | IPC G

Claim 7:
8. A verification device for verifying a design file for digital lithography, the verification device comprises:
a memory comprising the design file; and
a controller configured to:
access the design file;
detect areas of interest within the design file based on interactions between structures of cells within one or more hierarchical layers of the design file;
apply one or more compliance rules to the design file to determine compliance of the design file by:
detecting non-orthogonal edges within the areas of interest based on detecting an edge of a first structure of the structures being non-orthogonal with an edge of a second structure of the structures, wherein the first structure and the second structure are overlapping with each other;
detecting non-compliant overlapping structures within the areas of interest; and
detecting a non-compliant interaction between a reference layer of the design file and a target layer of the design file; and

verify the design file in response to a comparison of a number of the non-orthogonal edges, the non-compliant overlapping structures and the non-compliant interactions to a threshold, wherein the verified design file is output to a digital lithography device to pattern a substrate based on the verified design file.
