| ＜要旨＞A new wave is surging on a long history of microphase-separated nanostructures
in block copolymers as the self-assembled nanostructures leading to industrial
use as the new engineered plastics. Emphasis should be placed on both high
reproducibility and mass production of these ordered nanostructures through
self-assembling nanofabrication processes, expected as one of the powerful
counterparts of the top-down-type nanofabrication such as lithography and
beam processing. Here, recent progress of block copolymer lithography including
dry etching process toward the next generation semiconductor process is
briefly reviewed. Our approach based on total wet process using amphiphilic
liquid crystalline block copolymer films equipped with fully penetrated
transport channels is also introduced. Keywords: Block Copolymer / Lithography / Nanopatterning / Bottom-up Technology / Microphase Separation / Template / Self-assembly / Ordered Nanostructures |
