Abstract: Provided is a photosensitive resin composition that is developable with an aqueous alkaline solution and is suitable for the production of a color filter for an image sensor. The composition comprises an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, colorants and a solvent. As the colorants, a pigment and a dye are used in combination. The use of the composition enables the formation of fine pixels that exhibit excellent color reproduction and contrast. Therefore, the composition can be used to produce a high-resolution color filter for an image sensor.

Abstract: Disclosed is a pigment dispersion composition for producing a color filter. The pigment dispersion composition comprises a pigment, a binder resin, a dispersant and a solvent. The pigment is a blue anthraquinone pigment and is pretreated with a water-soluble inorganic salt and a wetting agent. The pigment dispersion composition can be used to produce a color filter for a color imaging device with good color separation and high transmittance.

Abstract: In a method for manufacturing an image sensor, an interlayer insulating layer including a metal line is formed on a semiconductor substrate. A lower electrode layer is formed on the metal line such that the lower electrode is connected with the metal line. A photoresist pattern corresponding to the metal line is formed on the lower electrode layer. The lower electrode layer is etched using the photoresist pattern to form a lower electrode connected with the metal line. The photoresist pattern is stripped using a solvent containing fluorine.

Abstract: A photosensitive resin composition for producing a color filter is provided. The composition comprises an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, a pigment, a dispersant and a solvent. As the dispersant, an amino group-containing maleic acid copolymer resin having long side chains is used. The composition can be used to form a pattern of ultra-fine pixels having a size of up to about 1.0 ?m×about 1.0 ?m without leaving any residue. Further provided is a high-resolution color filter for an image sensor produced using the composition.
