Patent number: 10199240Abstract: A substrate processing method and apparatus which can remove an anti-drying liquid, which has entered a three-dimensional pattern with recessed portions formed in a substrate, in a relatively short time. The substrate processing method includes the steps of: carrying a substrate, having a three-dimensional pattern formed in a surface, into a processing container, said pattern being covered with an anti-drying liquid that has entered the recessed portions of the pattern; heating the substrate and supplying a pressurizing gas or a fluid in a high-pressure state into the processing container, thereby forming a high-pressure atmosphere in the processing container before the anti-drying liquid vaporizes to such an extent as to cause pattern collapse and bringing the anti-drying liquid into a high-pressure state while keeping the liquid in the recessed portions of the pattern; and thereafter discharging a fluid in a high-pressure state or a gaseous state from the processing container.Type: GrantFiled: May 29, 2012Date of Patent: February 5, 2019Assignees: Toshiba Memory Corporation, Tokyo Electron LimitedInventors: Hidekazu Hayashi, Yohei Sato, Hisashi Okuchi, Hiroshi Tomita, Kazuyuki Mitsuoka, Mitsuaki Iwashita, Takehiko Orii, Gen You, Hiroki Ohno, Takayuki Toshima

Patent number: 10096462Abstract: A substrate processing method and apparatus for preventing evaporation of an anti-drying fluorine-containing organic solvent from a substrate during transportation of the substrate into a processing container and can prevent decomposition of a fluorine-containing organic solvent in the processing container. A substrate, the surface of which is covered with a first fluorine-containing organic solvent, is carried into a processing container.
