Patent ID: 7424700

Claim:
A method for making a photographic mask, the method comprising: determining a first contact area; processing information associated with the first contact area; determining whether a first optical compensation should be applied to the first contact area based on at least information associated with the first contact area; if the first optical compensation should be applied to the first contact area, applying the first optical compensation to the first contact area; processing information associated with the first optical compensation; determining a first distance between the first optical compensation and a second optical compensation or a second contact area; processing information associated with the first distance; adjusting the first optical compensation based on at least information associated with the first distance, wherein the processing information associated with the first contact area comprises: determining at least a first distance from a first edge of the first contact area to a first boundary of a conductive area, a second distance from a second edge of the first contact area to a second boundary of the conductive area, and a third distance from a third edge of the first contact area to a third boundary of the conductive area; processing information associated with the first distance, the second distance, and the third distance; determining a first area associated with the first distance, a second area associated with the second distance, and a third area associated with the third distance; wherein the determining whether a first optical compensation should be applied to the first contact area is performed based on at least information associated with the first distance, the second distance, the third distance, the first area, the second area, and the third area.
