제목 Directed Self-Assembly (DSA) for Next Generation Nanolithography
초록 DSA of BCPs can generate thermodynamically stable, periodic nanodomains(5~50nm) within guiding templates and has been one of representing candidates for extending optical lithography beyond its current limits. This talk will demonstrate soft-graphoepitaxy, a cost-effective, truly scalable, ultralarge-area BCP lithography, to direct lateral ordering in BCP thin films. Since the organic PR prepattern is readily disposable, this approach provides laterally ordered self-assembled nanopatterns and corresponding pattern transferred functional nanostructures without any trace of the structure directing prepattern. Furthermore, the microscale PR pattern can be transformed into a sub-30-nm scale ultrafine lamellar pattern. This talk will also introduce closely stacked highly anisotropic line patterns of supramolecular BCP thin film on a faceted surface. The supramolecule morphology prepared by blending the NPs consisted of highly ordered NPs arrays over an arbitrarily large-area.
