Patent number: 8890055Abstract: A method of producing a solid-state imaging device includes the steps of forming on a substrate a photoelectric conversion portion that receives light on a light-receiving surface and that photoelectrically converts the received light to generate a signal charge, forming above the light-receiving surface an optical waveguide that guides light to the light-receiving surface, and forming above the optical waveguide a color filter which colors light and from which colored light is emitted to the optical waveguide, wherein, in forming the color filter, the color filter is formed from a photosensitive resin film containing a dye by performing an exposure process and then performing a development process on the film, and in forming the optical waveguide, a core portion of the optical waveguide is formed so that the core portion absorbs exposure light radiated onto the photosensitive resin film when the exposure process is performed.Type: GrantFiled: December 2, 2009Date of Patent: November 18, 2014Assignee: Sony CorporationInventor: Akiko Ogino

Patent number: 8199284Abstract: An ink composition for a color filter includes about 100 parts by weight of a pigment dispersion, about 7 parts by weight to about 65 parts by weight of a thermosetting resin having hydroxyl group at a side chain of the thermosetting resin, about 0.015 part by weight to about 1.5 parts by weight of a thermal initiator, about 0.8 part by weight to about 15 parts by weight of an epoxy-based resin containing fluorine, and about 15 parts by weight to about 165 parts by weight of a solvent. A color filter substrate is manufactured using the ink composition for color filter. The ink composition for the color filter improves straightness of ink jetting through an ink-jetting nozzle and prevents the ink composition from spreading to neighboring pixels.Type: GrantFiled: September 24, 2010Date of Patent: June 12, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Yoon-Ho Kang, Byoung-Joo Kim, Jang-Sub Kim, Seong-Gyu Kwon

Publication number: 20080266354Abstract: A head unit includes first to fourth droplet ejection heads. The first and second droplet ejection heads are arranged along a first direction parallel to nozzle arrays so that the nozzles constitute a first consecutive long nozzle array when viewed from a second direction perpendicular to the first direction. Also, the nozzles of the third and fourth droplet ejection heads constitute a second consecutive long nozzle array. In the first to fourth droplet ejection heads the nozzle arrays are arranged side by side in the second direction and the first nozzle array is shifted with a half pitch in the first direction with respect to the second nozzle array when viewed from the second direction. The nozzles of the first and second droplet ejection heads are arranged so as not to overlap with the nozzles of the third and fourth droplet ejection heads when viewed from the second direction.Type: ApplicationFiled: July 1, 2008Publication date: October 30, 2008Applicant: SEIKO EPSON CORPORATIONInventor: TOMOMI KAWASE
