Publication number: 20090042113Abstract: A manufacturing method of a filter is provided. The manufacturing method includes steps as follows. First, a substrate is provided and a black matrix is formed on the substrate. The black matrix has a number of openings arranged in array. Next, a filter material is individually formed in the openings by inkjet printing or other methods, and the filter material includes a solvent and a dye mixed with the solvent. Thereafter, a thermal treatment is performed and an evaporation rate of the solvent during the thermal treatment is reduced, so as to cure the filter material. As the evaporation rate of the solvent is relatively slow, the filter material is still flowable during the thermal treatment. Hence, the cured filter material has a flat surface. The filter fabricated by the above manufacturing method has an even hue and a well flattened surface.Type: ApplicationFiled: March 3, 2008Publication date: February 12, 2009Applicant: Au Optronics CorporationInventors: Yong-Mao Lin, Wen-Lung Chen, Yung-Lung Lin, Fu-Chuan Tsai, Wei-Ya Wang, Chun-Chieh Tsao, Shu-Chin Lee

Publication number: 20080231681Abstract: A method of manufacturing a color filter is provided. First, a substrate is provided and then a partition, for example a black matrix, is formed on the substrate. The black matrix defines a plurality of first color filter areas and a plurality of second color filter areas corresponding to the first color filter areas on the substrate. Thereafter, a first color filter film and a second color filter film are formed in each of the first color filter areas and each of the second color filter areas corresponding thereto, respectively, such that a color filter is provided. The thickness of the first color filter film differs from the thickness of the second color filter film. Thus, images displayed by a transflective liquid crystal display with the aforementioned color filter have even colors.Type: ApplicationFiled: May 16, 2007Publication date: September 25, 2008Applicant: AU OPTRONICS CORPORATIONInventors: Wen-Lung Chen, Shu-Chin Lee, Fu-Chuan Tsai, Wei-Ya Wang, Yong-Mao Lin, Chun-Chieh Tsao

Patent number: 7205176Abstract: An MEMS mirror structure is formed using an etching process that forms sidewall oxide spacers while maintaining the integrity of the oxide layer formed over the reflective layer of the MEMS mirror structure. The discrete mirror structure is formed to include a reflective layer sandwiched between oxide layers and with a protect layer formed over the upper oxide layer. A spacer oxide layer is formed to cover the structure and oxide spacers are formed on sidewalls of the discrete structure using a selective etch process that is terminated when horizontal portions of the spacer oxide layer have cleared to expose the release layer formed below the discrete mirror structure and the protect layer. The superjacent protect layer prevents the spacer oxide etch process from attacking the upper oxide layer and therefore maintains the integrity of the upper oxide layer and the functionality of the mirror structure.Type: GrantFiled: October 29, 2004Date of Patent: April 17, 2007Assignee: Taiwan Semiconductor Manufacturing CompanyInventors: Fei-Yuh Chen, Wei-Ya Wang, Yuh-Hwa Chang, Tzu-Yang Wu

Publication number: 20060037933Abstract: A mirror process uses a tungsten passivation layer to prevent metal-spiking induced mirror bridging and improve mirror curvature. A mirror structure is patterned on a first sacrificial layer overlying a substrate. A tungsten passivation layer is then blanket deposited to cover the top and sidewalls of the mirror structure. A second sacrificial layer is formed overlying the tungsten passivation layer. A releasing process with an etchant including XeF2 is performed to remove the second sacrificial layer, the tungsten passivation layer and the first sacrificial layer simultaneously.Type: ApplicationFiled: August 23, 2004Publication date: February 23, 2006Inventors: Wei-Ya Wang, Chung-Yuan Cheng, Tzu-Yang Wu, Keven Hung, Fei-Yuh Chen
