Abstract:
The purpose of the present invention is to provide a high-pressure container which can form a process space having high cleanliness. A high-pressure container for performing a process using high pressure fluid on a substrate forms a hollow part by processing one surface except the widest surface of a flat rectangular parallelepiped block (5) made of metal. A container body is formed by forming a rare metal plating (7) on the inner wall surface facing the hollow part. When the hollow part functions as a through hole, a cover for opening/closing the hollow part is installed on one surface of the through hole. A second block for sealing the hollow part is installed on the other surface.
Abstract:
The purpose of the present invention is to provide a substrate processing method etc. capable of suppressing the volatilization of a fluorine-containing organic solvent for dry prevention until a substrate is carried into a processing container, and the decomposition of the fluorine-containing organic solvent within the processing container. A substrate (W) in which the surface is covered by a first fluorine-containing organic solvent is carried into a processing container (31). A high pressure fluid made of a second fluorine-containing organic solvent in which the boiling point is lower than the first fluorine-containing organic solvent is provided to the processing container (31). A high pressure fluid condition of a compound of the first and second fluorine-containing organic solvents is formed within the processing container (31). The first fluorine-containing organic solvent which covers the surface of the substrate is removed. A dried substrate (W) is obtained by discharging the fluid within the processing container (31) as the state of the high pressure fluid or gas.

Abstract:
현상처리시에 현상액과 현상액보다 비중이 작은 용액이 교반되어 이루어지는 혼합액을 기판의 표면에 공급하여 일정시간 동안 방치한다. 혼합액이 하층은 현상액, 상층은 용액인 2층으로 분리된 뒤에, 현상이 기판의 표면 전체에서 일괄적으로 이루어진다. 이렇게 함으로써 기판 표면 내에서 현상시작의 시간 차이가 발생하지 않고 균일하게 현상할 수 있어 기판 표면 내의 레지스트 패턴막의 선폭 균일성을 향상시킬 수 있다.
