Patent number: 11955350Abstract: An upper flow passage 181 is connected to a buffer space 182. The upper flow passage 181 has a constant cross-sectional shape and a processing fluid flows as a laminar flow in the upper flow passage 181. On the other hand, the buffer space 182 has a larger flow passage cross-sectional area than the upper flow passage 181. Thus, the processing fluid flowing in the upper flow passage 181 is released at once into the wide buffer space 182, whereby the pressure of the processing fluid decreases. A backflow of the processing fluid from the buffer space 182 to the upper flow passage 181 is prevented due to this pressure difference and the magnitude of a flow passage resistance of the upper flow passage 181 viewed from the buffer space 182.Type: GrantFiled: April 1, 2021Date of Patent: April 9, 2024Assignee: SCREEN HOLDINGS CO., LTD.Inventor: Noritake Sumi

Publication number: 20240105442Abstract: This invention relates to a replacement end time determination method in a process of replacing a liquid to be replaced by a processing fluid in a supercritical state and a substrate. In the invention, a density profile is obtained at each of a dry state where the liquid to be replaced is not present in a chamber and a wet state where the liquid to be replaced is present in the chamber by supplying and discharging the processing fluid into and from the chamber in accordance with a predetermined supply/discharge recipe while maintaining the processing fluid in a supercritical state. When both densities become substantially equal to each other after the density at the wet state becomes larger than the density at the dry state, the replacement of the liquid to be replaced by the processing liquid is regarded to be finished.Type: ApplicationFiled: January 5, 2022Publication date: March 28, 2024Inventor: Noritake SUMI

Publication number: 20240055277Abstract: In a substrate processing apparatus and a substrate processing method for processing a substrate by a processing fluid in a supercritical state in a processing space in a chamber, a heater for heating inside of the chamber below the substrate is arranged in the chamber, the substrate is carried into the processing space and heating by the heater is performed, the process fluid is supplied into the processing space and discharged from the processing space after the processing space is filled with the processing fluid in the supercritical state. The heating is stopped for a predetermined period from a time of introducing the processing fluid in the supercritical state into the processing space. While keeping inside the chamber a temperature suitable for a super-critical process, a temperature change causing a turbulence can be suppressed and the super-critical process to the substrate can be performed properly.Type: ApplicationFiled: December 22, 2021Publication date: February 15, 2024Inventors: Noritake SUMI, Masayuki ORISAKA

Patent number: 11715649Abstract: A processing fluid flows into a processing space SP by way of a flow passage and discharge openings 174, 178 having substantially the same cross-sectional shape as that of a gap space formed in a clearance between a wall surface of the processing space SP and a substrate holder 15. On the other hand, the processing fluid having passed through the processing space SP is discharged to an outside via discharge flow passages 183, 187 after flowing into the buffer space 182, 186 having substantially the same width as the gap space. From these, the processing fluid can be caused to flow into the buffer space 182, 186 while the laminar flow state is maintained in the gap space. Thus, the generation of a turbulence in the processing space SP can be suppressed.Type: GrantFiled: April 1, 2021Date of Patent: August 1, 2023Inventors: Noritake Sumi, Masayuki Orisaka

Patent number: 11658054Abstract: A substrate processing system includes a processing container body having an opening, a lid which closes an opening, a mover for relatively moving the lid with respect to the opening to open and close the opening, and a lock mechanism which locks the lid to the processing container body. The lock mechanism includes an arm member and a locking member. The arm member is provided on one of the processing container body and the lid and extends toward the other when the processing container body is located at a position where the lid is separated from the processing container body. The locking member restricts a displacement of the arm member by being engaged with a part of the arm member. This part is located beyond the gap space when the lid is at the separated position.Type: GrantFiled: January 20, 2021Date of Patent: May 23, 2023Inventor: Noritake Sumi

Patent number: 11621174Abstract: The disclosure provides a substrate processing apparatus that processes a surface of a substrate with a processing fluid in a supercritical state, in which the substrate is protected from the pressure fluctuation caused by partial vaporization of the processing fluid in the flow path. A substrate processing apparatus which processes a surface of a substrate with a processing fluid in a supercritical state includes a chamber housing provided therein with a processing space capable of housing the substrate and a flow path which receives the processing fluid from outside and guides the processing fluid to the processing space, and a fluid supply part which pressure-feeds the processing fluid to the flow path, wherein a plurality of bent parts which change a flow direction of the processing fluid are provided in the flow path.Type: GrantFiled: June 23, 2020Date of Patent: April 4, 2023Assignee: SCREEN Holdings Co., Ltd.Inventors: Noritake Sumi, Masanobu Sato, Masayuki Orisaka, Daiki Uehara

Publication number: 20230066729Abstract: This invention relates to a substrate processing technique for performing a pressure increasing step, a pressure keeping step and a pressure reducing step in this order in a processing container. A flow rate of a processing fluid in a processing space is suppressed to a second flow rate lower than a first flow rate while maintaining the processing space at a first pressure between the pressure increasing step and the pressure keeping step or in an initial stage of the pressure keeping step. In this way, the mutual diffusion between the processing fluid and a liquid in the processing space is promoted. After this diffusion proceeds, the substrate is dried by the discharge of the processing fluid from the processing space.Type: ApplicationFiled: August 23, 2022Publication date: March 2, 2023Inventors: Zhida WANG, Koji ANDO, Noritake SUMI, Chiaki MORIYA, Daiki UEHARA

Publication number: 20220165599Abstract: In a substrate processing apparatus in which a substrate is transported into multiple chambers by using multiple transport mechanisms, while a first transport unit is responsible for the transport of the substrate into the first chamber and the transport of the substrate out from the second chamber, the second transport unit is responsible for the transfer of the substrate from the first chamber to the second chamber. With respect to a transfer zone which is a transport route of the substrate from the first chamber to the second chamber, the first transport unit is arranged above and the second transport unit is arranged below. Since entry into the transfer zone is exclusively allowed, the two transport units can operate individually while avoiding mutual interference.Type: ApplicationFiled: February 26, 2020Publication date: May 26, 2022Inventors: Hiroyuki KAWAHARA, Koji HASHIMOTO, Noriyuki KIKUMOTO, Noritake SUMI
