摘要： Methods involving the self-assembly of block copolymers are described herein, in which by beginning with openings (in one or more substrates) that have a targeted CD (critical dimension), holes are formed, in either regular arrays or arbitrary arrangements. Significantly, the percentage variation in the average diameter of the formed holes is less than the percentage variation of the average diameter of the initial openings. The formed holes (or vias) can be transferred into the underlying substrate(s), and these holes may then be backfilled with material, such as a metallic conductor. Preferred aspects of the invention enable the creation of vias with tighter pitch and better CD uniformity, even at sub-22 nm technology nodes.

摘要： 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.

摘要： 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.
