“… 2 BCPs as versatile materials can be used for state-of-the-art lithographic techniques to shrink the feature sizes beyond current optical resolution limits. 3 , 4 , 5 Various highly ordered self-assembly morphologies with larger areas and high resolution have been achieved via graphoepitaxy or chemoepitaxy methods. 6 , 7 , 8 , 9 In recent years, significant progress and interest in DSA of BCPs have been achieved in the fabrication of integrated circuits (ICs) devices, such as nonvolatile memory, 10 fin field-effect transistors, 11 and photonic nanodevices.…”
