Abstract:
An opening in a substrate is formed, e.g., using optical lithography, with the opening having sidewalls whose cross section is given by segments that are contoured and convex. The cross section of the opening may be given by overlapping circular regions, for example. The sidewalls adjoin at various points, where they define protrusions. A layer of polymer including a block copolymer is applied over the opening and the substrate, and allowed to self-assemble. Discrete, segregated domains form in the opening, which are removed to form holes, which can be transferred into the underlying substrate. The positions of these domains and their corresponding holes are directed to predetermined positions by the sidewalls and their associated protrusions. The distances separating these holes may be greater or less than what they would be if the block copolymer (and any additives) were to self-assemble in the absence of any sidewalls.
Abstract:
A method of forming a layered structure comprising a self-assembled material comprises: disposing a non-crosslinking photoresist layer on a substrate; pattern-wise exposing the photoresist layer to first radiation; optionally heating the exposed photoresist layer; developing the exposed photoresist layer in a first development process with an aqueous alkaline developer, forming an initial patterned photoresist layer; treating the initial patterned photoresist layer photochemically, thermally and/or chemically, thereby forming a treated patterned photoresist layer comprising non-crosslinked treated photoresist disposed on a first substrate surface; casting a solution of an orientation control material in a first solvent on the treated patterned photoresist layer, and removing the first solvent, forming an orientation control layer; heating the orientation control layer to effectively bind a portion of the orientation control material to a second substrate surface; removing at least a portion of the treated photoresist and, optionally, any non-bound orientation control material in a second development process, thereby forming a pre-pattern for self-assembly; optionally heating the pre-pattern; casting a solution of a material capable of self-assembly dissolved in a second solvent on the pre-pattern and removing the second solvent; and allowing the casted material to self-assemble with optional heating and/or annealing, thereby forming the layered structure comprising the self-assembled material.
Abstract:
A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl carbonate group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl carbonate group. Using a suitable nucleophile, the pendant pentafluorophenyl carbonate group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.

Abstract:
A method of forming a layered structure comprising a domain pattern of a self-assembled material utilizes a negative-tone patterned photoresist layer comprising non-crosslinked developed photoresist. The developed photoresist is not soluble in an organic casting solvent for a material capable of self-assembly. The developed photoresist is soluble in an aqueous alkaline developer and/or a second organic solvent. A solution comprising the material capable of self-assembly and the organic casting solvent is casted on the patterned photoresist layer. Upon removal of the organic casting solvent, the material self-assembles, thereby forming the layered structure.
