  • Publication number: 20130344242
    Abstract: The use of self-assembled block copolymer structures to produce advanced lithographic patterns relies on control of the orientation of these structures in thin films. In particular, orientation of cylinders and lamellae perpendicular to the plane of the block copolymer film is required for most applications. The preferred method to achieve orientation is by heating. The present invention involves the use of polarity-switching top coats to control block copolymer thin film orientation by heating. The top coats can be spin coated onto block copolymer thin films from polar casting solvents and they change composition upon thermal annealing to become “neutral”. Top coats allow for the facile orientation control of block copolymers which would otherwise not be possible by heating alone.

  • Publication number: 20130280497
    Abstract: The present invention involves the use of random copolymer top coats that can be spin coated onto block copolymer thin films and used to control the interfacial energy of the top coat-block copolymer interface. The top coats are soluble in aqueous weak base and can change surface energy once they are deposited onto the block copolymer thin film. The use of self-assembled block copolymers to produce advanced lithographic patterns relies on their orientation control in thin films. Top coats potentially allow for the facile orientation control of block copolymers which would otherwise be quite challenging.

  • Publication number: 20130209757
    Abstract: The present invention uses vacuum deposited thin films of material to create an interface that non-preferentially interacts with different domains of an underlying block copolymer film. The non-preferential interface prevents formation of a wetting layer and influences the orientation of domains in the block copolymer. The purpose of the deposited polymer is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.
