Pattern forming method and imprint mold manufacturing method

Abstract

In one embodiment, a pattern forming method includes: forming a functional layer having a functional group to cross-link a first polymer on a substrate; forming a diblock copolymer layer having the first polymer and a second polymer on the functional layer; self-assembling the diblock copolymer layer to form a self-assembled layer, the self-assembled layer having a first domain corresponding to the first polymer, and a plurality of second domains corresponding to the second polymer and surrounded by or interposed in the first domain; cross-linking the first polymer in the self-assembled layer with the functional group in the functional layer to form a bonding layer disposed in the self-assembled layer and bonded to the functional layer; and washing or etching the self-assembled layer to remain the bonding layer.
