Publication number: 20260084191Abstract: A substrate processing apparatus includes a substrate holder to hold a substrate, a treatment liquid supplier to supply a treatment liquid onto a surface of the substrate to be cleaned, a cooler to supply a cooling medium for cooling the substrate, an impactor to apply an impact to a treatment liquid layer, and a controller. The controller controls the cooler to cool the treatment liquid layer to a temperature lower than a freezing point, and controls the impactor to apply an impact to a starting point of forced freezing located away from a starting point of spontaneous freezing in the treatment liquid layer formed on the surface of the substrate to be cleaned, when a temperature of the treatment liquid layer formed reaches a set temperature that is lower than a freezing point and higher than a temperature at which spontaneous freezing occurs.Type: ApplicationFiled: February 10, 2025Publication date: March 26, 2026Applicant: Kioxia CorporationInventors: Mana TANABE, Kosuke TAKAI, Ryoji YOSHIKAWA, Kaori UMEZAWA, Kenji MASUI

Publication number: 20240096653Abstract: According to one embodiment a substrate treatment apparatus incorporates, into a frozen film, a contaminant adhered to a substrate surface by freezing a liquid film on the surface. The apparatus includes a placement part configured to rotate the substrate, a liquid supply part configured to supply a liquid via a nozzle to the frozen film including the contaminant, a moving part configured to move the nozzle parallel to the substrate surface, and a controller configured to control a rotation of the substrate by the placement part, a supply of the liquid by the liquid supply part, and a movement of the nozzle by the moving part. The controller rotates the substrate by controlling the placement part, supplies the liquid to the frozen film by controlling the liquid supply part, and moves the nozzle from a perimeter edge vicinity to a rotation center vicinity of the substrate by controlling the moving part.Type: ApplicationFiled: September 19, 2023Publication date: March 21, 2024Inventors: Kensuke DEMURA, Satoshi NAKAMURA, Masaya KAMIYA, Minami NAKAMURA, Kosuke TAKAI, Mana TANABE, Kaori UMEZAWA

Patent number: 11776823Abstract: A substrate processing method includes a process of cooling a substrate to below a freezing point of a processing liquid using a cooling fluid brought into contact with the substrate opposite. While the substrate is cooled to below the freezing point of the processing liquid, a droplet of processing liquid is dispensed onto a surface of the substrate at a specified location of a foreign substance. The droplet then forms a frozen droplet portion at the specified location. The frozen droplet portion is then thawed.Type: GrantFiled: August 10, 2022Date of Patent: October 3, 2023Assignee: Kioxia CorporationInventors: Mana Tanabe, Kosuke Takai, Kenji Masui, Kaori Umezawa

Patent number: 11185895Abstract: According to one embodiment, a first liquid is supplied on a first face of a substrate. The first liquid has a pH with which a surface zeta potential of the substrate becomes negative and a surface zeta potential of a foreign substance attaching to the first face becomes positive. Then, a solidified layer in which at least part of the first liquid has been solidified is formed by cooling the substrate down to be equal to or lower than a solidification point of the first liquid. Thereafter, the solidified layer is melted.Type: GrantFiled: March 12, 2019Date of Patent: November 30, 2021Assignee: TOSHIBA MEMORY CORPORATIONInventors: Mana Tanabe, Hideaki Sakurai, Kosuke Takai, Kyo Otsubo, Minako Inukai
