摘要
A method for processing a substrate includes providing a set of patterned structures separated by a first gap on the substrate and directing first implanting ions to the substrate at a first ion energy, where the first implanting ions are effective to impact the substrate in regions defined by the first gap. The method also includes directing depositing ions to the substrate where the second ions are effective to deposit material on at least a portion of the set of patterned structures to form expanded patterned structures, where the expanded patterned structures are characterized by a second gap smaller than the first gap. The method further includes directing second implanting ions to the substrate at a second ion energy, where the second implanting ions effective to impact the substrate in regions defined by the second gap, the second ion energy comprising a higher ion energy than the first ion energy.
