ABSTRACT:
The invention includes a method of patterning radiation. The radiation is simultaneously passed through a structure and through a subresolution assist feature that is transmissive of at least a portion of the radiation. The subresolution assist feature alters a pattern of radiation intensity defined by the structure relative to a pattern of radiation intensity that would be defined in the absence of the subresolution assist feature. The invention further includes methods of forming radiation-patterning tools, and the radiation-patterning tools themselves.
