Patent number: 7732122Abstract: The invention relates to a process for producing photonic crystals by first providing an inorganic photoresist which, on illumination with energy greater than the electronic band gap of the photoresist, exhibits a phase alteration. Illumination of the photoresist with a laser beam whose energy is lower than the electronic band gap of the photoresist but whose intensity at the focal point is so high that nonlinear effects occur there nevertheless results in a phase alteration in the photoresist.

In forming the cores, when the irradiation light reaches the bottom surface of the PET substrate portion, most of the irradiation light is absorbed by the colored layer, so that there is little irradiation light reflected from the bottom surface of the PET substrate portion. This significantly reduces the irradiation light reflected diffusely from the PET substrate portion and reaching the photosensitive resin layer to thereby effectively suppress the surface roughening of the side surfaces of the cores.Type: ApplicationFiled: September 18, 2009Publication date: March 18, 2010Applicant: NITTO DENKO CORPORATIONInventors: Takami Hikita, Junichi Fujisawa, Yusuke Shimizu

Publication number: 20100068653Abstract: A manufacturing method of an optical waveguide device which is capable of suppressing the surface roughening of core side surfaces of an optical waveguide when the optical waveguide is formed on a roughened surface of a substrate. An under cladding layer is formed on a roughened surface of a substrate made of a material that absorbs irradiation light, and then a photosensitive resin layer for the formation of cores is formed thereon. Irradiation light is directed toward this photosensitive resin layer to expose the photosensitive resin layer in a predetermined pattern to the irradiation light. When the irradiation light transmitted through the photosensitive resin layer for the formation of the cores and the under cladding layer reaches the surface of the substrate, the irradiation light is absorbed by the substrate, so that there is little irradiation light reflected from the surface of the substrate.Type: ApplicationFiled: August 18, 2009Publication date: March 18, 2010Applicant: NITTO DENKO CORPORATIONInventors: Junichi Fujisawa, Yusuke Shimizu

Publication number: 20100062377Abstract: The present invention relates to a method for manufacturing a color filter and a color filter manufactured by using the same. More particularly, the present invention pertains to a method for manufacturing a color filter, which includes performing plasma treatment of a black matrix (BM) pattern formed on a substrate to increase a difference in ink repellency of the black matrix pattern and a pixel unit, and a color filter manufactured by using the same. When the production method of the present invention is used, it is possible to provide the color filter in which color mixing does not occur in a pixel unit or between pixel units during discharging of ink by using an inkjet printing process, discoloration due to unfilling does not occur, a surface is uniform, and there is an insignificant step in the pixel unit or between the pixel units.Type: ApplicationFiled: March 6, 2008Publication date: March 11, 2010Applicant: LG CHEM, LTD.Inventors: Dae-Hyun Kim, Dong-Chang Choi, Kyung-Soo Choi, Ho-Chan Ji, Hyun-Sik Kim, Geun-Young Cha, Sung-Hyun Kim, Jae-Joon Kim, Min-A Yu, Mi-Ae Kim, Mi-Kyoung Kim
