Abstract
An electro-deposition apparatus deposits a first pattern of a lithographic mask. The electro-deposition apparatus then deposits a second pattern of the lithographic mask, at least partially offset from the first pattern. The resulting lithographic mask includes a first pattern having a minimum feature resolution size and maximum pitch, and a second pattern having the same minimum feature resolution size and maximum pitch. The first pattern and second pattern are at least partially offset such that a fractional portion of the second pattern is realized and light transmission is more precisely controlled.
