Patent number: 10589305Abstract: In a coating apparatus, a nozzle moving mechanism selectively grips any one of a plurality of coating solution nozzles, moves the gripped coating solution nozzle and a solvent nozzle together, and moves at least the solvent nozzle to a solvent suction unit. The moved solvent nozzle is caused to dispense a solvent to the solvent suction unit, and the gripped coating solution nozzle is caused to suck the solvent retained in the same solvent suction unit to which the solvent has been dispensed. Thus, since dispensation and suction of the solvent are done in the same solvent suction unit, the quantity of the solvent used can be held down. Further, a supply line for supplying the solvent does not need to be provided for the suction unit. The construction of the suction unit can therefore be made simple, and its cost can be held down.Type: GrantFiled: January 27, 2016Date of Patent: March 17, 2020Assignee: SCREEN Holdings Co., Ltd.Inventor: Yasuo Takahashi

Patent number: 10569297Abstract: A substrate is rotated with a holding rotator to form a coating liquid film on the substrate, and at least a part of an excess of the coating liquid is pushed out toward a periphery edge of the substrate by a centrifugal force caused by the rotation of the substrate to build up the excess of the coating liquid along the periphery edge of the substrate. Moreover, gas is blown to the periphery edge of the substrate through a gas nozzle to exhaust the excess of the coating liquid building up at the periphery edge. Blowing the gas toward the periphery edge of the substrate through the gas nozzle makes the coating liquid unbalanced that builds up without being exhausted outside the substrate due to its surface tension. Accordingly, the rotation achieves the coating liquid film having a uniform thickness while the coating liquid film is formed to be thick.Type: GrantFiled: February 12, 2016Date of Patent: February 25, 2020Assignee: SCREEN Holdings Co., Ltd.Inventors: Masahiko Harumoto, Yuji Tanaka

Patent number: 10549312Abstract: In one embodiment, a spin coating apparatus includes a coating liquid feeding module to drop a coating liquid onto a substrate, and a motor to rotate the substrate. The module drops a first drop amount of the coating liquid onto the substrate at a first discharge rate, while the motor rotates the substrate at a first number of rotations. The module drops a second drop amount of the coating liquid onto the substrate at a second discharge rate larger than the first discharge rate, while the motor rotates the substrate at a second number of rotations smaller than the first number of rotations, after the first drop amount of the coating liquid is dropped. The module discharges the coating liquid onto the substrate at a third discharge rate smaller than the second discharge rate, after the coating liquid is discharged onto the substrate at the second discharge rate.Type: GrantFiled: February 11, 2016Date of Patent: February 4, 2020Assignee: Toshiba Memory CorporationInventor: Keisuke Nakazawa

Patent number: 10539133Abstract: A method of treating, tuning, assembling, and/or overhauling a twin rotor device (200, 1200) includes applying a coating material (102) on an internal set of working surfaces (218, 222, 224, 226, 228, 1218, 1222, 1224, 1226, 1228) of the twin rotor device when at least partially assembled. The coating may be factory or field applied to a new or used twin rotor device. The working surfaces may be uncoated or previously coated and may be built-up as the coating material forms a coating (206, 1206) on at least some of the working surfaces. Manufacturing variations of a pair of rotors (220, 1220) and a housing (210, 1210) may be compensated by the coating.

Patent number: 10385446Abstract: A group of inventions is related to process equipment to process surfaces in mass production, particularly, vacuum process equipment to apply thin film coatings with set optical, electrical and other parameters. The technical result is to ensure a capability of processing flexible large substrates, as well as small substrates with a high degree of coating uniformity, with an ability to utilize a wide range of technologies and process devices, as well as to have a highly effective useful operation of applied materials. The proposed technical result is obtained by a method of applying thin film coatings on substrates, which are placed on rotating drums, which consequently move along the processing zones with the same constant linear and angular speeds. Furthermore, a ratio between the linear and angular speeds of the drum is selected so that each surface point of the drum will complete at least two full revolutions while passing through the processing zone.Type: GrantFiled: January 14, 2014Date of Patent: August 20, 2019Assignee: THE BATTERIES SP.
