摘要:
In one embodiment, a resist material to be used in an imprint process includes a diluent monomer having a hydroxyl group and at least one functional group selected from a vinyl ether group, an epoxy group and an oxetanyl group. The material further includes a dendrimer having at least two reactive groups for photo-cationic polymerization. The material further includes a photo-acid generator as a polymerization initiator.
摘要:
In accordance with an embodiment, a method of forming a pattern includes forming a first layer on a fabrication target film, making a mold and the first layer push each other to form a protrusion on the fabrication target film, and forming first and second regions, forming a block copolymer layer including first and second blocks in the first and second regions, phase-separating the block copolymer layer, forming second and third layers in the first region, and forming fourth and fifth layers in the second region; and removing the third and fifth layers. The first region is surrounded by the first layer and the protrusion. The second region is surrounded by the first layer and contacts the first region via the protrusion. The third layer is surrounded by the second layer. The fifth layer is surrounded by the fourth layer.
