Methods for aligning polymer films and related structures

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.
