Patent ID: 8477288

Claim:
A digital exposure method for forming a plurality of patterns on a substrate, the method comprising: producing a graphic data system file corresponding to each of the plurality of patterns to be formed on the substrate, including a first graphic data system file corresponding to a first pattern of the plurality of patterns for exposing a first area of the substrate, and a second graphic data system file corresponding to a second pattern of the plurality of patterns for exposing a second area of the substrate, and combining the first graphic data system file and the second graphic data system file into a combined graphic data system file, wherein a plurality of first layers of the first pattern and a plurality of second layers of the second pattern are respectively combined into one layer, wherein the second layers respectively correspond to the first layers, in combining the first graphic data system file and the second graphic data system file; generating digital micromirror device on/off data from the graphic data system file; and exposing the substrate in response to the digital micromirror device on/off data.
