    摘要: A pattern-forming method includes: forming a pattern on an upper face side of a substrate; applying a first composition to a sidewall of the pattern; forming a resin layer by applying a second composition to an inner face side of the sidewall of the pattern coated with the first composition; allowing the resin layer to separate into a plurality of phases; and removing at least one of the plurality of phases. The first composition contains a first polymer. The second composition contains a second polymer. The second polymer includes a first block having a first structural unit and a second block having a second structural unit. The polarity of the second structural unit is higher than the polarity of the first structural unit. Immediately before forming of the resin layer, a static contact angle θ (°) of water on the sidewall of the pattern satisfies inequality (1). α ≥ θ ≥ α + β 2 ( 1 )

    摘要: A composition for pattern formation includes a first polymer, a second polymer and a solvent. The first polymer includes: a first block including a first structural unit derived from a substituted or unsubstituted styrene; and a second block including a second structural unit other than the first structural unit. The second polymer includes: the first structural unit; and a group bonding to at least one end of a main chain thereof and including a polar group. The polar group is preferably a hydroxy group or a carboxyl group. A number average molecular weight of the second polymer is preferably no greater than 6,000. A mass ratio of the second polymer to the first polymer is preferably no less than 0.15 and no greater than 0.4. The solvent preferably comprises a compound comprising a hydroxyl group and an alkyl ester group.

    摘要: A pattern-forming method includes forming a base pattern having recessed portions on a front face side of a substrate directly or via other layer. The recessed portions of the base pattern are filled with a first composition to form a filler layer. Phase separation of the filler layer is allowed to form a plurality of phases of the filler layer. A part of the plurality of phases of the filler layer is removed to form a miniaturized pattern. The forming of the base pattern includes: forming a resist pattern on the front face side of the substrate; forming a layer of a second polymer on lateral faces of the resist pattern; and forming a layer of a third polymer that differs from the second polymer on a surface of the substrate or on a surface of the other layer.
