20130209757 | USING CHEMICAL VAPOR DEPOSITED FILMS TO CONTROL DOMAIN ORIENTATION IN BLOCK COPOLYMER THIN FILMS - 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. | 08-15-2013 |
20130266780 | Polylactide/Silicon-containing Block Copolymers for Nanolithography - The present invention includes a diblock copolymer system that self-assembles at very low molecular weights to form very small features.

20130280497 | Anhydride Copolymer Top Coats for Orientation Control of Thin Film Block Copolymers - 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. | 10-24-2013 |
20130344242 | Anhydride Copolymer Top Coats for Orientation Control of Thin Film Block Copolymers - 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. | 12-26-2013 |
