摘要:
A pattern forming method, includes: exposing a resist film with actinic rays or radiation a plurality of times; and heating the resist film at a first temperature in at least one interval between the exposures.
摘要:
A pattern forming method, comprising: (A) coating a substrate with a positive resist composition of which solubility in a positive developer increases and solubility in a negative developer decreases upon irradiation with actinic rays or radiation, so as to form a resist film; (B) exposing the resist film; and (D) developing the resist film with a negative developer containing butyl acetate.
摘要:
The present invention is directed to a pattern forming method, comprising: forming a resist film by applying, to a substrate, a resin composition containing a resin of which solubility in a positive developer which is an alkali developer increases and solubility in a negative developer containing an organic solvent decreases under an action of an acid, wherein the resin composition is capable of forming a resist film of which solubility in the positive developer increases and solubility in the negative developer decreases upon irradiation with actinic rays or radiation; exposing the resist film with EUV light; and developing the resist film after the exposing with the negative developer containing an organic solvent.

The present invention relates to a pattern forming method, comprising: (A) coating a substrate with a positive resist composition of which solubility in a positive developer increases and solubility in a negative developer decreases upon irradiation with actinic rays or radiation, so as to form a resist film; (B) exposing the resist film; and (D) developing the resist film with a negative developer,
wherein (D) developing the resist film with a negative developer is performing development with a developer containing a solvent represented by formula (1) or a developer containing a solvent represented by formula (2):
wherein R and R' each independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxyl group, an alkoxycarbonyl group, a carboxyl group, a hydroxy group, a cyano group or a halogen atom, and R and R' may combine with each other to form a ring:
