Patent ID: 8688254

Claim:
A system for direct write patterning, comprising: first and second direct write exposure units; a single data processing unit in communication with the first and second direct write exposure units, the single data processing unit being configured to generate a common writing instruction based on pattern data and send the common writing instruction to each of the first and second direct write exposure units; a first sub-data processing unit communicatively positioned between the single data processing unit and the first direct write exposure unit and configured to fine-tune the common writing instruction for the first direct write exposure unit based on variations between the first and second direct write exposure units; a second sub-data processing unit communicatively positioned between the single data processing unit and the second direct write exposure unit and configured to fine-tune the common writing instruction for the second direct write exposure unit based on the variations between the first and second direct write exposure units; wherein the common writing instruction includes on-off stream information and stage movement information; wherein the first sub-data processing unit is further configured to fine-tune the on-off stream information for an imaging beam in the first direct write exposure unit and fine-tune the stage movement information for a substrate stage in the first direct write exposure unit; at least one input cassette in communication with each of the first and second direct write exposure units; at least one output cassette in communication with each of the first and second direct write exposure units; first and second input buffer cassettes respectively associated with the first and second direct write exposure units and respectively positioned between each of the at least one input cassettes and the first and second direct write exposure units; and first and second output buffer cassettes respectively associated with the first and second direct write exposure units and respectively positioned between each of the at least one output cassettes and the first and second direct write exposure units.
