Publication number: 20240355644Abstract: A substrate processing system provided with a plurality of apparatuses to perform a patterning on a plurality of the substrates, wherein a transfer container accommodating the plurality of substrates is transferred to the plurality of apparatuses in a sequential manner. The substrate processing system includes: a first apparatus of the plurality of apparatuses, which is configured to form a metal-containing resist film on each substrate; a second apparatus of the plurality of apparatuses, which is configured to perform a development on the metal-containing resist film after exposure; and an atmosphere regulator having an accommodation space where the substrates, on each of which the metal-containing resist film before being subjected to the development is formed, are accommodated and configured to regulate an atmosphere of the accommodation space so as to regulate a degree of progress of a reaction of the metal-containing resist film on each substrate.Type: ApplicationFiled: April 19, 2024Publication date: October 24, 2024Inventors: Shinsuke TAKAKI, Hiroki TADATOMO, Yoji SAKATA, Tomoya ONITSUKA, Naoki SHIBATA

Patent number: 9984905Abstract: An interface station of a coating and developing treatment system has: a cleaning unit cleaning at least a rear surface of a wafer before the wafer is transferred into an exposure apparatus; an inspection unit inspecting the rear surface of the cleaned wafer whether the wafer is exposable, before it is transferred into the exposure apparatus; wafer transfer mechanisms including arms transferring the wafer between the units and a wafer transfer control part controlling operations of the wafer transfer mechanisms. When it is determined that a state of the wafer becomes an exposable state by re-cleaning in the cleaning unit as a result of the inspection, the wafer transfer control part controls the wafer transfer mechanisms to transfer the wafer again to the cleaning unit.Type: GrantFiled: August 31, 2016Date of Patent: May 29, 2018Assignee: Tokyo Electron LimitedInventors: Masahiro Nakaharada, Yoji Sakata, Akira Miyata, Shinichi Hayashi, Suguru Enokida, Tsunenaga Nakashima
