Patent ID: 8551556

Claim:
A method of producing a mask structure comprising the steps of: positioning a print head in a first position such that a droplet of masking material ejected therefrom at said first position is directed toward a location over a surface of a substrate; ejecting from said print head a first droplet of masking material which forms either in physical contact with said substrate or in physical contact with a layer formed over said substrate a first print-patterned feature, said first print-patterned feature spreading to a first lateral width over said surface of said substrate to thereby define a first lateral edge and a first centerline; repositioning said print head to a second position such that a droplet of masking material ejected therefrom at said second position is directed toward a location over said first print-patterned feature; and ejecting from said print head a second droplet of masking material which forms exclusively over and in physical contact with a portion of said first print-patterned feature a second print-patterned feature, said second print-patterned feature spreading to a second lateral width over said first print-patterned feature to thereby define a second lateral edge and a second centerline, said first lateral width being greater than said second lateral width; wherein the second position is such that the first lateral edge and the second lateral edge are aligned in a plane which is roughly perpendicular to a plane of said surface of said substrate and said first and second centerlines are not collinear.
