摘要： Methods and a structure. The method includes applying a solution including two or more immiscible polymers to a substructure including features having at least one sidewall and a bottom surface. The immiscible polymers include a first polymer and a second polymer. The at least one sidewall includes a material. A selective chemical affinity of the first polymer for the material is greater than a selective chemical affinity of the second polymer for the material. The first polymer is segregated from the second polymer. The first polymer selectively migrates to the at least one sidewall, resulting in the first polymer being disposed between the at least one sidewall and the second polymer. One or more immiscible polymers is selectively removed. At least one immiscible polymer remains, resulting in forming structures including the substructure and the immiscible polymer remaining. Two additional methods and a structure are also included.

摘要： Disclosed herein is a method of controlling the orientation of microphase-separated domains in a block copolymer film, comprising forming an orientation control layer comprising an epoxy-containing cycloaliphatic acrylic polymer on a surface of a substrate, irradiating and/or heating the substrate to crosslink the orientation control layer, and forming a block copolymer assembly layer comprising block copolymers which form microphase-separated domains, on a surface of the orientation control layer opposite the substrate. The orientation control layer can be selectively cross-linked to expose regions of the substrate, or the orientation control layer can be patterned without removing the layer, to provide selective patterning on the orientation control layer. In further embodiments, bilayer and trilayer imaging schemes are disclosed.
