    摘要: An optical mask for providing a pattern for portion of an electronic device, such as a magnetic recording transducer, is disclosed. The optical mask includes a device feature and at least one detached correction feature. The device feature includes a corner corresponding to a device corner of the pattern. The device corner has an angle of greater than zero degrees and less than one hundred eighty degrees. The at least one detached correction feature resides in proximity to but is physically separated from the corner. Each of the at least one detached correction feature is sub-resolution.
