Patent number: 8485513Abstract: A control apparatus obtains information identifying sheets stored in an MFP to be caused to perform printing for printing a printed object to be subjected to jacketed book binding, wherein this information is stored in the MFP. The control apparatus stores thicknesses of respective paper sheets as information about paper sheets. From this information and from the information obtained from the MFP, the control apparatus creates a table indicative of the correspondence between the respective paper sheets stored in the MFP and their thicknesses. Further, on receiving a selection of paper sheets to be used for printing for the printed object and a number of these paper sheets, the control apparatus determines a thickness of each paper sheet by making a reference to the table and calculates the spine jacket width by multiplying the thickness by the number of paper sheets.Type: GrantFiled: January 30, 2009Date of Patent: July 16, 2013Assignee: Konica Minolta Business Technologies, Inc.Inventors: Kunihiko Sugimoto, Tsuyoshi Morimoto, Atsushi Ito, Taro Yamamoto

Patent number: 8474396Abstract: Provided is a developing apparatus configured to slim the resist pattern while reducing the number of developing modules. A room temperature developing liquid and a high temperature developing liquid to modify the surface layer of a resist pattern can be supplied from a common nozzle to a substrate disposed on a mount table. Although both developing liquids may be sequentially discharged by switching between the supply line for the room temperature developing liquid and the supply line for the high temperature developing liquid, it is also possible to join these supply lines for supplying the room temperature developing liquid from the former supply line, and then adjust the ratio of the flow rates between both supply lines, and then supply the mixed liquid of the developing liquids as a high temperature developing liquid.Type: GrantFiled: July 14, 2010Date of Patent: July 2, 2013Assignee: Tokyo Electron LimitedInventors: Masahiro Fukuda, Atsushi Ookouchi, Taro Yamamoto

Patent number: 8445189Abstract: The temperature of a developing solution is varied depending on the type of resist or the resist pattern. The developing solution is applied while scanning a developer nozzle having a slit-shaped ejection port that has a length matching the width of the effective area of the substrate. After leaving the substrate with the developing solution being coated thereon for a predetermined period of time, a diluent is supplied while scanning a diluent nozzle, thereby substantially stopping the development reaction and causing the dissolved resist components to diffuse. A desired amount of resist can be quickly dissolved through the control of the developing solution temperature, while the development can be stopped before the dissolved resist components exhibit adverse effect through the supply of the diluent a predetermined timing, whereby achieving a pattern having a uniform line width and improved throughput.Type: GrantFiled: February 10, 2011Date of Patent: May 21, 2013Assignee: Tokyo Electron LimitedInventors: Taro Yamamoto, Kousuke Yoshihara, Hideharu Kyouda, Hirofumi Takeguchi, Atsushi Ookouchi

Patent number: 8398319Abstract: A developing apparatus including a substrate holder that holds a substrate horizontally; means for atomizing a surface treatment liquid used to improve wettability of the substrate with a developer; a first spray nozzle that sprays the atomized surface treatment liquid onto the substrate; and a developer supply nozzle that supplies a developer onto the substrate to which the substrate treatment liquid has been sprayed. The surface tension of the atomized surface treatment liquid with respect to the substrate is lower than the surface tension of the surface treatment liquid with respect to the substrate. The atomization suppresses the fact that the surface treatment liquid gathers on a certain portion of the surface of the substrate. The surface treatment liquid can be easily supplied onto the entire surface of the substrate, and improve wettability of the substrate with the developer.Type: GrantFiled: March 5, 2010Date of Patent: March 19, 2013Assignee: Tokyo Electron LimitedInventors: Hiroshi Arima, Yuichi Yoshida, Taro Yamamoto, Kousuke Yoshihara
