Abstract:
According to one embodiment, a pattern formation method is disclosed. The method can include a preparation process, a first layer formation process, a block copolymer layer formation process, and a contact process. The preparation process prepares a pattern formation material including a polymer including a first chemical structure including carbon, hydrogen, and a first group. The first group includes one of a vinyl group, a hydroxy group, or a first element. The first layer formation process forms a first layer on a base body. The first layer includes the pattern formation material. The block copolymer layer formation process forms a block copolymer layer on the first layer. The block copolymer layer includes a first polymer and a second polymer. The block copolymer layer formation process includes forming first and second regions. The contact process causes the block copolymer layer to contact a metal compound including a metallic element.

Claim (Index 1):
A pattern formation method, comprising:\n a preparation process of preparing a pattern formation material including a polymer including a first chemical structure, the first chemical structure including carbon, hydrogen, and a first group, the first group including at least one of a vinyl group, a hydroxy group, or a first element, the first element including at least one selected from the group consisting of fluorine, chlorine, and bromine, the pattern formation material not including a carbonyl group, or a concentration of carbonyl groups in the pattern formation material being 0.0005 mol/g or less; a first layer formation process of forming a first layer on a base body, the first layer including the pattern formation material; a block copolymer layer formation process of forming a block copolymer layer on the first layer, the block copolymer layer including a first polymer and a second polymer, the block copolymer layer formation process including forming a first region and a second region by causing phase separation of the first polymer and the second polymer, the first region including the first polymer, the second region including the second polymer, the second polymer including a carbonyl group; and a contact process of causing the block copolymer layer to contact a metal compound including a metallic element.
