Patent number: 7686588Abstract: A liquid chemical supply system that performs accurate pressure feedback control and controls the discharge flow rate of liquid chemical with high precision, even when the pressure setting value of the operation pressure differs due to changes in the type of liquid chemical, includes a pump having a pump chamber and an operation chamber separated by a diaphragm comprised of a flexible membrane. The intake and discharge of liquid chemical is performed in accordance with the change in pressure inside the operation chamber. An electro-pneumatic regulator supplies operation gas pressure to the operation chamber. A plurality of pressure sensors having different pressure detection ranges is provided for detecting the operation gas pressure. A controller selectively employs any of the detection results of the plurality of sensors in accordance with the pressure setting value of the operation air that is set for each use, and performs pressure feedback control.Type: GrantFiled: October 17, 2006Date of Patent: March 30, 2010Assignees: OCTEC Inc., CKD CorporationInventors: Katsuya Okumura, Tetsuya Toyoda, Tomohiro Ito, Akira Murakumo, Atsuyuki Sakai

Patent number: 7649369Abstract: In accordance with an increase in speed, a wiring structure has rapidly become more microscopic and thinner and a wiring layer has become extremely thin, and therefore, giving a contact load to a probe for the inspection as has been conventionally done causes damage to a wiring layer and an insulation layer because the probe penetrates not only the oxide film but also the wiring layer or because of a concentration stress from the probe. On the other hand, decreasing the contact load causes unstable continuity between the probe and an electrode pad. It is an object of the present invention to surely and stably inspect an object to be inspected by breaking an oxide film with a low stylus pressure.Type: GrantFiled: March 3, 2005Date of Patent: January 19, 2010Assignees: Octec Inc., TOKYO Electron LimitedInventors: Katsuya Okumura, Toshihiro Yonezawa

Publication number: 20090293647Abstract: Because a sample holder 100 is composed of a plurality of convex parts 1 provided on a top face of a base substance 2, and the plurality of convex parts 1 are spherical surfaces 1a formed of a single crystal or amorphous material, frictional wear of the sample at contact parts between a sample 4 and the convex parts 1 is reduced, thereby making it possible to inhibit particle generation. Further, because a joining layer 3 is formed of a single crystal or amorphous material, there is no defect that particles scattered on the sample holder 100 fill up it, which makes it possible to easily keep it in a clean state by cleaning, and it is possible to effectively reduce reattachment of particles to the sample 4.Type: ApplicationFiled: September 28, 2006Publication date: December 3, 2009Applicants: KYOCERA CORPORATION, OKUTEC CO., LTD.Inventors: Takeshi Muneishi, Toshihiko Uemura, Katsuya Okumura

Patent number: 7575664Abstract: A cathode potential is applied to a conductive layer formed on a substrate having a depression pattern. A plating solution in electrical contact with an anode is supplied to the conductive layer to form a plating film on the conductive layer. At this time, the plating solution is supplied by causing an impregnated member containing the plating solution to face the conductive layer. Since the plating solution stays in the depression, a larger amount of plating solution is supplied than on the upper surface of the substrate, and the plating rate of the plating film in the depression increases. Consequently, the plating film can be preferentially formed in the depression such as a groove or hole.Type: GrantFiled: May 24, 2005Date of Patent: August 18, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Tetsuo Matsuda, Hisashi Kaneko, Katsuya Okumura
