    摘要: Techniques are disclosed for realizing a two-dimensional target lithography feature/pattern by decomposing (splitting) it into multiple unidirectional target features that, when aggregated, substantially (e.g., fully) represent the original target feature without leaving an unrepresented remainder (e.g., a whole-number quantity of unidirectional target features). The unidirectional target features may he arbitrarily grouped such that, within a grouping, all unidirectional target features share a common target width value. Where multiple such groupings are provided, individual groupings may or may not have the same common target width value. In some cases, a series of reticles is provided, each reticle having a mask pattern correlating to a grouping of unidirectional target features. Exposure of a photoresist material via the aggregated series of reticles substantially (e.g., fully) produces the original target feature/pattern. The pattern decomposition techniques may be integrated into any number of patterning processes, such as litho-freeze-litho-etch and litho-etch-litho-etch patterning processes.

    摘要: Double patterning techniques and structures are generally described. In one example, a method includes depositing a first photoresist to a semiconductor substrate, forming a first integrated circuit (IC) pattern in the first photoresist, the first IC pattern comprising one or more trench structures, protecting the first IC pattern in the first photoresist from actions that form a second IC pattern in a second photoresist, depositing the second photoresist to the first IC pattern, and forming the second IC pattern in the second photoresist, the second IC pattern comprising one or more structures that are sufficiently close to the one or more trench structures of the first IC pattern to cause scumming of the second photoresist in the one or more trench structures of the first IC pattern.

    摘要: Techniques are disclosed for double patterning of a lithographic feature using a barrier layer between the pattern layers. In some cases, the techniques may be implemented with double patterning of a one- or two-dimensional photolithographic feature, for example. In some embodiments, the barrier layer is deposited to protect a first photoresist pattern prior to application of a second photoresist pattern thereon and/or to tailor (e.g., shrink) one or more of the critical dimensions of a trench, hole, or other etchable geometric feature to be formed in a substrate or other suitable surface via lithographic processes. In some embodiments, the techniques may be implemented to generate/print small features (e.g., less than or equal to about 100 nm) including one- and two-dimensional features/structures of varying complexity.
