Patent number: 12722248Abstract: A processing apparatus includes a rotatable turntable and four chuck tables disposed on the turntable. When the turntable with the four chuck tables disposed thereon is intermittently turned about its central axis, the wafer held on each of the chuck tables is moved to and positioned in a first processing position, a second processing position, and a third processing position where the wafer is processed. Three types of processing processes are able to be carried out on the wafers without the wafers being spaced from holding surfaces of the chuck tables.Type: GrantFiled: October 24, 2023Date of Patent: September 1, 2026Assignee: DISCO CORPORATIONInventors: Makoto Maejima, Yuto Maeda

Publication number: 20260084263Abstract: A polishing surface dressing method includes: a dressing step of dressing a polishing surface; a polishing surface shape measuring step of measuring the shape of the polishing surface based on a displacement amount in a first direction orthogonal to the polishing surface and a movement position in the second direction of the dressing section that is in contact with the polishing surface; a determination step of determining appropriateness of the shape of the polishing surface measured in the polishing surface shape measuring step; and a condition change step of changing a contact condition in which the dressing section makes contact with the polishing surface in the dressing step, when the shape of the polishing surface is determined to be “No Good”, and the dressing step is performed again based on the contact condition changed in the condition change step.Type: ApplicationFiled: August 12, 2025Publication date: March 26, 2026Inventors: Mami SAEKI, Jiro GENOZONO, Yuto MAEDA, Ryotaro HINATA, Takamasa SUZUKI

Patent number: 12451389Abstract: There is provided a conveying apparatus having a holding surface that holds a held surface of a substrate to convey the substrate. The conveying apparatus includes a holding pad that gets contact with an outer circumferential part of the held surface of the substrate or a side surface of the substrate and forms a space to be filled with water between the held surface of the substrate and the holding surface, a movement unit that causes the holding pad to move in such a direction as to get closer to or further away from the held surface, a water supply unit that supplies the water to the space, and a suction unit that sucks the water with which the space is filled and improves a force of holding the substrate. The conveying apparatus holds the substrate by the holding pad and conveys the substrate with the interposition of the water.Type: GrantFiled: February 17, 2022Date of Patent: October 21, 2025Assignee: DISCO CORPORATIONInventors: Yuto Maeda, Naoaki Tadami

Patent number: 12247933Abstract: An X-ray phase imaging apparatus includes a control device configured or programmed to make a notification prompting a user to update or generate a corresponding second X-ray image when determining that a decrease in an image quality of an X-ray phase contrast image generated based on a first X-ray image obtained by imaging a subject and a second X-ray image obtained by imaging without the subject arranged does not fall within a predetermined allowable range and/or determining that the second X-ray image associated with an imaging condition has not been stored.Type: GrantFiled: August 1, 2023Date of Patent: March 11, 2025Assignee: Shimadzu CorporationInventors: Kana Kojima, Yuto Maeda

Patent number: 12072302Abstract: This X-ray phase imaging system includes a plurality of gratings including a first grating that is irradiated with X-rays from an X-ray source and a second grating that is irradiated with X-rays from the first grating. The X-ray phase imaging system includes an imaging unit that optically images a subject and one or both of the first grating and the second grating.Type: GrantFiled: October 31, 2022Date of Patent: August 27, 2024Assignee: Shimadzu CorporationInventors: Bunta Matsuhana, Yuto Maeda, Jiro Masuda, Kana Kojima, Takahiro Doki
