Publication number: 20110199442Abstract: The back pressure of an ink tank is controlled. A porous body is arranged inside the ink tank, the lower end of the porous body contacts an ink, and the ink ascends inside the porous body due to a capillary force. The upper end of the porous body is not immersed in the ink, and a maximum ascending force acts upon the ink stored in the ink tank. Therefore, the ink does not leak from a discharge head located lower than the ink tank. Further, because the ink is accumulated under the porous body and the amount of the ink contacting the porous body is small, components of the ink are less susceptible to deterioration.Type: ApplicationFiled: April 1, 2011Publication date: August 18, 2011Applicant: ULVAC, INC.Inventors: Takahiro Miyata, Masao Murata, Satoshi Shiba, Mitsuru Yahagi, Jyunpei Yuyama

Patent number: 7999907Abstract: Exfoliation of an etching stopper is prevented. A color filter of the present invention includes an inorganic protection film (etching stopper) composed mainly of SnO2. Since the inorganic protection film as such not only has a high specific resistance but also has a linear expansion coefficient close to the linear expansion coefficient of a transparent electrode, the inorganic protection film is not exfoliated from the transparent electrode or the resin layer even if an object to be processed is heated. Since the inorganic protection film and the transparent electrode can be formed in the same film forming chamber, the time required to produce the color filter can be shortened as compared to in the conventional technique.Type: GrantFiled: February 12, 2010Date of Patent: August 16, 2011Assignee: Ulvac, Inc.Inventors: Hirohisa Takahashi, Isao Sugiura, Atsushi Ohta, Satoru Ishibashi

Publication number: 20110180388Abstract: [Object] To provide a plasma processing method and a plasma processing apparatus having high coverage property and excellent in-plane uniformity. [Solving Means] When sputtered particles that are beat out from a target by plasma are deposited on a surface of a substrate, those sputtered particles are decomposed by the plasma to thus generate active species, and then deposited on the surface of the substrate. Accordingly, a deposition mode similar to plasma CVD is obtained, and sputtering deposition with high coverage property and excellent in-plane uniformity is enabled. Particularly, since a high-frequency electric field and a ring-shaped magnetic neutral line are used for a plasma source, it is possible to efficiently generate plasma that has extremely high density in a region in which a magnetic field is zero. That plasma realizes plasma processing with high in-plane uniformity by arbitrarily adjusting a formation position and a size of the magnetic neutral line.Type: ApplicationFiled: August 5, 2008Publication date: July 28, 2011Applicant: ULVAC, INC.Inventors: Yasuhiro Morikawa, Koukou Suu
