摘要:
Provided is a method of producing a curable composition for imprints including (A) a polymerizable monomer, (B) a polymerization initiator, and (C) a solvent which is capable of effectively suppressing lifting or separation of patterns, excellent in coatability, and excellent in time-dependent stability. The method of producing a curable composition for imprints comprises preparing one species of liquid (D) which contains at least either one of the polymerizable monomer (A) and the polymerization initiator (B), passing the liquid (D) through a filter, and then adding the solvent (C).
摘要:
A photosensitive composition comprises (A) a sulfonium or iodonium salt having an anion represented by one of formulae (I) and (II):
wherein Y represents an alkylene group substituted with at least one fluorine atom, and R represents an alkyl group or a cycloalkyl group. the photosensitive composition further comprising: (D) a resin soluble in an alkali developer; and (E) an acid crosslinking agent that crosslinks with the resin (D).
摘要:
A positive resist composition comprising: a resin which increases solubility in an alkali developing solution by an action of an acid and comprises a repeating unit containing a lactone structure and a cyano group, a repeating unit containing a first group selected from groups represented by the formulae (pI) to (pV) as defined herein and a repeating unit containing a second group selected from groups represented by the formulae (pI) to (pV) as defined herein which is different from the first group; a compound which generates an acid upon irradiation of an actinic ray or a radiation; and a solvent.
