Abstract: Aligned pitch-quartered patterning approaches for lithography edge placement error advanced rectification are described. For example, a method of fabricating a semiconductor structure includes forming a first patterned hardmask on a semiconductor substrate. A second hardmask layer is formed on the semiconductor substrate. A segregated di-block co-polymer is formed on the first patterned hardmask and on the second hardmask layer. Second polymer blocks are removed from the segregated di-block co-polymer. A second patterned hardmask is formed from the second hardmask layer and a plurality of semiconductor fins is formed in the semiconductor substrate using first polymer blocks as a mask. A first fin of the plurality of semiconductor fins is removed. Subsequent to removing the first fin, a second fin of the plurality of semiconductor fins is removed.
