Abstract:
1. A pattern forming method, comprising: forming a functional layer including a functional group to cross-link a first polymer on a substrate; forming a diblock copolymer layer including 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 including a first domain corresponding to the first polymer, and a plurality of second domains corresponding to the second polymer, the second domains being surrounded by the first domain 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 divide the self-assembled layer into a lower layer and an upper layer covering the lower layer, the lower layer being bonded to the functional layer and the upper layer being not bonded to the functional layer; and washing or etching the self-assembled layer to remove the upper layer and leave the lower layer.
