제목 Simultaneous Improvement of Block Copolymer Self-Assembly Kinetics and Pattern Quality by Solvothermal Annealing
초록 Directed self-assembly (DSA) of block copolymers (BCPs) has been one of the promising nanofabrication methodologies for resolving the resolution limit of optical lithography. However, there are some critical challenges of high-χ BCPs because it needs long annealing time due to low chain mobility. It can also have a diffusive interface resulting from the significantly reduced χ parameter due to the solvent screening effect. In this study, we report that solvothermal annealing can be used as the simultaneously effective method for a rapid self-assembly as well as for producing sharp interfaces between two blocks. Owing to the extremely rapid self-assembly and sharp interfaces, solvothermal annealing has the advantages of high throughput and improved pattern quality.
