    摘要: A plurality of reticles for printing structures in the same lithography level includes an alignment structure pattern within a same relative location in each reticle. Each set of process segmentations in a grating has a reticle segmentation pitch, which is common across all gratings in the plurality of reticles. Within each pair of alignment structure patterns that occupy the same relative location in any two of the plurality of reticles, the process segmentations in one reticle are shifted relative to the process segmentations in the other reticle by a fraction of a reticle segmentation pitch. After printing all patterns in the plurality of reticles, a composite printed process segmentation structure on the substrate includes printed segmentation structures that are spaced by 1/n times the printed segmentation pitch. The pattern for the next level can be aligned to the composite printed process segmentation structure in a single alignment operation.

    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.

    摘要: A resist pattern on a substrate is formed using an imageable resist layer on the surface of a substrate. The imageable resist layer comprises a silicon-incorporated polystyrene-diene block copolymer having a silicon weight percent of at least about 5 percent. The imageable layer is prepared by reacting a polystyrene-diene block copolymer with a silicon-containing compound in the presence of a platinum catalyst. In a preferred embodiment, the poly(styrene)-diene block copolymers are hydrosilylated by hydrosiloxanes using a platinum-divinyl tetramethyl disiloxane catalyst.
