Title: Julia Cushen: Innovator in Block Copolymer Thin Films
Introduction
Julia Cushen is a prominent inventor based in Austin, TX (US). She has made significant contributions to the field of materials science, particularly in the development of advanced thin films. With a total of 7 patents, her work focuses on enhancing the functionality and application of block copolymer films.
Latest Patents
Cushen's latest patents include innovative methods for using chemical vapor deposited films to control domain orientation in block copolymer thin films. This technology involves vacuum-deposited thin films that create an interface, which interacts non-preferentially with different domains of an underlying block copolymer film. This non-preferential interface prevents the formation of a wetting layer and influences the orientation of domains in the block copolymer. The goal is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.
Another notable patent involves anhydride copolymer top coats for orientation control of thin film block copolymers. This concept utilizes random copolymer top coats that can be spin-coated onto block copolymer thin films to control the interfacial energy of the top coat-block copolymer interface. These top coats are soluble in aqueous weak bases and can alter surface energy once deposited onto the block copolymer thin film. The use of self-assembled block copolymers to produce advanced lithographic patterns relies heavily on their orientation control in thin films. These top coats potentially allow for easier orientation control of block copolymers, which would otherwise be quite challenging.
