    摘要: An underlayer to be patterned with a composite pattern is formed on a substrate. The composite pattern is decomposed into a first pattern and a second pattern, each having reduced complexity than the composite pattern. A hard mask layer is formed directly on the underlying layer. A first photoresist is applied over the hard mask layer and lithographically patterned with the first pattern, which is transferred into the hard mask layer by a first etch. A second photoresist is applied over the hard mask layer. The second photoresist is patterned with the second pattern to expose portions of the underlying layer. The exposed portions of the underlying layer are etched employing the second photoresist and the hard mask layer, which contains the first pattern so that the composite pattern is transferred into the underlying layer.
