Abstract:
Described herein are structures and methods for preparing photobuckets for lithography, e.g. photolithography or electron-beam lithography. One method includes arranging photobuckets on a material to be etched using lithography and providing a layer of a first material at least on inner side walls of the photobuckets, followed by filling the photobuckets with a second material. The second material is more lithosensitive than the first material and the first material could be not lithosensitive at all. Layering each photobucket from the inner side wall(s) of the photobucket towards the center of the photobucket with materials that are increasingly more lithosensitive results in an improved control of lithographic patterning by reducing or eliminating edge placement errors of accidentally exposing photobuckets that should not have been exposed.

Claim (Index 23):
An assembly for forming nanostructures, the assembly comprising:\n a material to be etched; and a non-lithosensitive structure provided over the material to be etched, the structure comprising a plurality of openings extending in a direction that is substantially perpendicular to the material to be etched, the plurality of openings having a layer of a first material and a layer of a second material provided at least on side walls of the plurality of openings, the layer of the first material being provided closer to the side walls of the plurality of openings than the layer of the second material, wherein the second material is more lithosensitive than the first material.
