Abstract:
The embodiments disclose a method of using a trimmed imprinted resist and chemical contrast pattern to guide a directed self-assembly (DSA) of a predetermined lamellar block copolymer (BCP), creating chromium (Cr) lamellar guiding lines using the BCP and DSA in a dry Cr lift-off process and etching the Cr lamellar guiding line patterns into a substrate to fabricate the imprint template.
