Abstract
Embodiments described herein relate to substrate processing methods. The methods include forming a patterned hardmask material on a substrate, forming first mandrel structures on exposed regions of the substrate, and depositing a gap fill material on the substrate over the hardmask material and the first mandrel structures. The first mandrel structures are removed to expose second region of the substrate form second mandrel structures comprising the hardmask material and the gap fill material and fin structures are deposited on the substrate using the second mandrel structures as a mask.
