Patent ID: 8902522

Claim:
A method for fabricating a color filter for a solid state imaging device using an ultra-short wavelength exposing device, the method comprising: forming a coating film by coating a colored photosensitive resin composition for each of various colors on a substrate, the colored photosensitive resin composition including: a colorant, a binder resin having an acid value between 20 and 200 mg KOH/g, a photopolymerizable compound, and a photoinitiator reacting at a wavelength of 300 nm or less, and a solvent selected from the group consisting of ethylene glycol monoalkyl ethers, ethylene glycolalkyletheracetates, diethylene glycodialkyl ethers, alkylene glycolalkyletheracetates, aromatic hydrocarbons, ketones alcohols, cyclic esters, and combinations thereof; exposing to light through a mask by irradiating ultra-short wavelength laser into a potential color pattern area of the coating film by an ultra-short wavelength KrF scanner having a wavelength of 248 nm; and conducting a development on the coating film by removing an unexposed coating area that is not exposed to laser in the exposing step to form a colored pattern.
