Publication number: 20240321598Abstract: A substrate cleaning device includes a substrate holder, a lower-surface brush, a first liquid nozzle and a second liquid nozzle. The substrate holder holds a substrate in a horizontal attitude. The lower-surface brush is configured to be movable between a processing position for cleaning of the substrate and a waiting position that overlaps with the substrate held by the substrate holder in an up-and-down direction. Further, the lower-surface brush is configured to be rotatable about an axis extending in the up-and-down direction. The lower-surface brush cleans a lower surface of the substrate by coming into contact with the lower surface of the substrate. The first liquid nozzle discharges a cleaning liquid to a center portion of the lower-surface brush, at a waiting position. The second liquid nozzle discharges a cleaning liquid to an end portion of the lower-surface brush, at the waiting position.Type: ApplicationFiled: June 30, 2022Publication date: September 26, 2024Inventors: Takuma TAKAHASHI, Tomoyuki SHINOHARA, Junichi ISHII, Kazuki NAKAMURA, Takashi SHINOHARA, Nobuaki OKITA, Yoshifumi OKADA

Patent number: 12036583Abstract: A cleaner comes into contact with a lower-surface center region of a substrate held by a first holder, so that the lower-surface center region is cleaned. The cleaner comes into contact with a lower-surface outer region of the substrate rotated by a second holder, so that the lower-surface outer region of the substrate is cleaned. During cleaning of the lower-surface center region, the second holder is rotated about a vertical axis while not holding the substrate. Alternatively, during cleaning of the lower-surface center region, the gas injector arranged between the cleaner and the second holder injects gas toward the substrate from a first height spaced apart from the substrate by a predetermined distance. Further, during drying of the lower-surface center region, the gas injector injects gas toward the substrate from a second height closer to the substrate than the first height.Type: GrantFiled: June 30, 2022Date of Patent: July 16, 2024Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Tomoyuki Shinohara, Junichi Ishii, Kazuki Nakamura, Yoshifumi Okada, Takuma Takahashi, Takashi Shinohara, Nobuaki Okita

Patent number: 11393593Abstract: In a biological simulation apparatus, an operation unit represents a structure domain where tissues of a biological organ exist by a structure mesh model based on a Lagrange description and a fluid domain where fluid inside the biological organ exists by an ALE fluid mesh model based on an ALE description method. In a fluid-structure interaction simulation, the operation unit deforms the structure mesh model, and then deforms the ALE fluid mesh model so as to form no gap on a first interface between a domain where a site other than a certain site of the biological organ in the structure domain exists and the fluid domain or no overlap with the structure domain.

Patent number: 11167994Abstract: For evaluating a polycrystalline silicon rod to be used as a raw material for production of FZ Si single crystals, novel evaluation values (values of characteristicsĂ—amount of crystals) including the amount of crystals grown in the growth direction (radial direction) are defined and the homogeneity in crystal characteristics in the growth direction (radial direction) is evaluated. Specifically, the homogeneity of the polycrystalline rod is evaluated by sampling a plurality of specimen plates each having, as a principal plane thereof, a cross-section perpendicular to a radial direction of the polycrystalline rod grown by a Siemens method at equal intervals in the radial direction, determining values of characteristics of the crystals of the specimen plates by measurements, and by using evaluation values obtained by multiplying amounts of the crystals (relative amounts of the crystals) at sites where the specimen plates have been sampled by the values of the crystal characteristics.Type: GrantFiled: September 4, 2020Date of Patent: November 9, 2021Assignee: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Shuichi Miyao, Shigeyoshi Netsu, Junichi Okada
