A method of forming a semiconductor structure includes forming a first array of mandrels on a hardmask layer disposed on an uppermost surface of a semiconductor substrate. First sidewall image transfer spacers are formed on opposing longitudinal sidewalls of each mandrel in the first array of mandrels. A second array of mandrels is formed on the hardmask layer. Each mandrel in the second array of mandrels is laterally separated from each mandrel in the first array of mandrels by the first sidewall image transfer spacers. Second sidewall image transfer spacers are formed on opposing transversal sidewalls of the first array of mandrels and the second array of mandrels. Portions of the second sidewall image transfer spacers are selectively removed to define a crosslink fin pattern to be transferred to the semiconductor substrate.
