Abstract: An actinic-ray-sensitive or radiation-sensitive resin composition which is capable of improving line edge roughness (LER) and inhibiting pattern collapse, a resist film and a pattern forming method each using the same, a method for preparing an electronic device, and an electronic device are provided. The actinic-ray-sensitive or radiation-sensitive resin composition contains: (A) a resin having repeating units having a structure represented by any one of the following general formulae (I-1) to (I-3), and repeating units containing at least one selected from the group consisting of a lactone structure, a sultone structure, and a cyano group; and (B) a compound that generates an acid by irradiation with actinic rays or radiations.

Abstract: An actinic-ray- or radiation-sensitive resin composition according to the present invention includes (A) a resin to be decomposed to increase its solubility in an alkali developer when acted on by an acid, and (B) a compound represented by the general formula (1-1) below.

Abstract: Provided are an actinic-ray- or radiation-sensitive resin composition that excels in the sensitivity, roughness characteristics and exposure latitude, and a method of forming a pattern using the same. The composition includes (A) a resin that when acted on by an acid, is decomposed to thereby increase its solubility in an alkali developer, and (B) a compound that when exposed to actinic rays or radiation, is decomposed to thereby generate an acid, the compound being any of compounds of general formula (1-1) below.

Abstract: An object of the present invention is to provide an actinic-ray-sensitive or radiation-sensitive resin composition which is significantly excellent in terms of exposure latitude, is capable of forming a favorable rectangular pattern profile, and exhibits low dissolution of the components into an immersion liquid when performing immersion exposure, and a resist film and a pattern forming method each using the same composition. The actinic-ray-sensitive or radiation-sensitive resin composition contains (A) a compound represented by formula (I) and capable of generating an acid upon irradiation of actinic-rays or radiations, and (B) a resin capable of increasing the solubility in an alkaline developer by the action of an acid.

Abstract: Provided is an actinic-ray-sensitive or radiation-sensitive resin composition that is excellent in depth of focus and density distribution dependency, and an actinic-ray-sensitive or radiation-sensitive film and a pattern forming method using the same. An actinic-ray-sensitive or radiation-sensitive resin composition according to the present invention includes (A) a first resin which decomposes by an action of an acid to increase a solubility of the first resin in an alkaline developer, (B) a second resin which includes at least one of a fluorine atom and a silicon atom and is different from the first resin, and (C) an onium salt which includes a nitrogen atom in a cation portion and generates an acid by being decomposed upon irradiation with actinic-ray or radiation.

Abstract: Provided are an actinic-ray-sensitive or radiation-sensitive resin composition which has improved development defect and is capable of forming a good pattern shape, an actinic-ray-sensitive or radiation-sensitive film formed using the composition, and a pattern forming method using the composition. The actinic-ray-sensitive or radiation-sensitive resin composition includes (A) a compound which generates an acid represented by the following general formula (I) or (I?) upon irradiation with an actinic-ray or a radiation, and (B) a resin which decomposes by an action of an acid to increase a solubility of the resin in an alkaline developer [each of the symbols in the general formulae (I) and (I?) indicates the meaning described in Claims].

Abstract: The present invention provides an artificial mutant of GFP having a novel emission peak, i.e., a fluorescent protein having an emission peak at 424 nm comprising an amino acid sequence represented by SEQ ID NO: 1, in which each of the amino acid residues at the 66th position and the 175th position is replaced and at least one of the amino acid residues at the 72nd position and the 206th position is further replaced, or a fluorescent protein having an emission peak at 424 nm and a pH-independent fluorescence intensity, in which each of the amino acid residues at the 65th, 145th, 148th, 46th and/or 203rd positions is further substituted. The fluorescent protein of the invention emits fluorescence having an emission peak at 424 nm and can be visually distinguished by its ultramarine color from other fluorescent proteins. The fluorescent protein has a pH-independent fluorescence intensity which is not affected by pH changes.
