摘要:
The present invention provides an actinic ray-sensitive or radiation-sensitive resin composition with which a pattern having an excellent pattern collapse suppressing property and excellent LWR performance can be obtained. In addition, the present invention also provides a resist film, a pattern forming method, and a method for manufacturing an electronic device, each regarding the actinic ray-sensitive or radiation-sensitive resin composition. The actinic ray-sensitive or radiation-sensitive resin composition of the present invention includes a resin whose solubility in a developer is changed by the action of an acid, a photoacid generator represented by General Formula (b1), and a solvent, in which the photoacid generator represented by General Formula (b1) is a compound that generates an acid having a pka of 1.0 or less upon irradiation with actinic rays or radiation

An EUV lithographic structure includes an EUV photosensitive resist layer disposed on a hardmask layer, wherein the EUV lithographic structure is free of an antireflective coating. An organic adhesion layer can be provided between the hardmask layer and the EUV photosensitive resist layer. The hardmask layer can include an uppermost oxide hardmask layer, an intermediate hardmask layer, and a lowermost oxide hardmask layer, wherein the EUV photosensitive resist layer is disposed on the uppermost oxide hardmask layer. Also described are methods for patterning the EUV lithographic structures.

A photosensitive element for use as a flexographic printing plate comprises a support, an elastomeric photopolymerizable layer, and a matted layer disposed above a surface of the photopolymerizable layer opposite the support, comprising a polymeric binder and at least one matting agent which is capable of being anchored in the surface of the photopolymerizable layer. Also described is a process for preparing such a photosensitive element and a process for preparing a flexographic printing plate from the photosensitive element.
摘要:
A recess for deaeration is formed in the surface of a resist film by using the photolithography technique, a photomask is allowed to come into contact with projections for close contact on both sides or around the recess for deaeration, and evacuation is performed via the recess for deaeration, thereby enhancing close contact between the photomask and the projections for close contact. With the configuration, a resist pattern having an accurate recess while preventing diffraction of light is formed.

A method for producing a presensitized printing plate is disclosed. The method comprises the steps ofproviding a photosensitive layer on a supportspraying a resin dissolved or dispersed in an organic solvent on the surface of the photosensitive layer so that sprayed droplets of the resin solution or dispersion are stuck onto the surface of the photosensitive layer to form dots of the resin, anddrying the droplets stuck on the surface of the photosensitive layer so that the surface of the photosensitive layer is dotted with the particles of the resin.
