Patent number: 10651029Abstract: The controller is programmed to cause a low-surface-tension liquid supply unit to supply a liquid film of a low-surface-tension liquid to a front surface of a substrate so as to form a liquid film of the low-surface-tension liquid. The controller is programmed to control the substrate rotating unit and the inert gas supply unit so that an inert gas is supplied toward the rotational center position while rotating the substrate, thereby forming an opening spreading from the rotational center position to be formed in the liquid film, and enlarging the opening in a direction away from the rotational center position, and to control the landing-position changing unit to change the landing position of the low-surface-tension liquid to at least two positions except the rotational center position in accordance with enlargement of the opening so that the landing position is placed outside the peripheral edge of the opening.Type: GrantFiled: December 22, 2016Date of Patent: May 12, 2020Assignee: SCREEN Holdings Co., Ltd.Inventors: Hiroaki Takahashi, Kazunori Fujikawa, Tomonori Kojimaru, Tomomasa Ishida, Ayumi Higuchi, Naozumi Fujiwara, Kana Komori, Shota Iwahata

Patent number: 9455134Abstract: A hydrophobizing agent vapor is supplied to a substrate and a surface of the substrate including a pattern is hydrophobized. Thereafter, the substrate is dried by vaporizing the hydrophobizing agent. The substrate to be processed is maintained in a state of not contacting water until it is dried after being hydrophobized. Collapse of a pattern formed on the substrate surface is thereby suppressed or prevented.Type: GrantFiled: March 5, 2015Date of Patent: September 27, 2016Assignee: SCREEN Holdings Co., Ltd.Inventors: Masahiro Kimura, Tomonori Kojimaru, Tetsuya Emoto, Manabu Okutani, Masayuki Otsuji

Patent number: 8821974Abstract: A liquid hydrophobizing agent is supplied to a substrate and a surface of the substrate is hydrophobized. A solvent, lower in surface tension than water and capable of dissolving the hydrophobizing agent, is supplied to the substrate in a pre-drying rinsing step. Thereafter, the substrate is dried. The substrate to be processed is maintained in a state of not contacting water until it is dried after being hydrophobized.Type: GrantFiled: August 18, 2011Date of Patent: September 2, 2014Assignee: Dainippon Screen Mfg.

Patent number: 7964042Abstract: After the rinsing processing is completed, the rotation speed of the substrate is reduced from 600 rpm to 10 rpm to form a puddle-like DIW liquid film. After the supply of DIW is stopped, the control unit waits for a predetermined time (0.5 seconds) so that the film thickness t1 of the puddle-like liquid film becomes approximately uniform. Then, IPA is discharged to a central part of the surface of the substrate at a flow rate of 100 (mL/min) for instance. By the supply of IPA, DIW is replaced with IPA at the central part of the surface of the substrate to form a replaced region. Further, after three seconds of IPA supply, the rotation speed of the substrate is accelerated from 10 rpm to 300 rpm. This causes the replaced region to expand in a radial direction of the substrate so that the entire surface of the substrate is replaced with the low surface-tension solvent.Type: GrantFiled: July 24, 2008Date of Patent: June 21, 2011Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Tomonori Kojimaru, Katsuhiko Miya
