A tank includes a container part having an upper wall, a sidewall and a bottom wall to store a processing liquid therein, a liquid discharge passage installed at a position higher than a liquid surface of the processing liquid stored in the container part to discharge the processing liquid into the container part, and a gas discharge passage installed at a position higher than the liquid surface to discharge a gas into the container part. The liquid discharge passage discharges the processing liquid from the liquid discharge port so that the processing liquid is brought into contact with a portion above the liquid surface of an inner surface of the sidewall. The gas discharge passage discharges the gas from the gas discharge port so that the gas is brought into contact with a portion above the liquid surface of an inner surface of the container part.

Tank, substrate processing apparatus, and method of using the tank

A developing treatment method for performing a developing treatment on a resist film on a substrate, includes the following. (A) supplying a developing solution to the substrate and developing the resist film to form a resist pattern; (B) supplying a water-based cleaning liquid to the developed substrate to clean the substrate with the water-based cleaning liquid; (C) applying an aqueous solution of a water-soluble polymer to the substrate cleaned with the water-based cleaning liquid to form a hydrophilic layer having a hydrophilic property on a surface of the substrate; and (D) cleaning the substrate on which the hydrophilic layer has been formed, with a rinse liquid. (B) includes (a) accelerating a rotation speed of the substrate; and (b) after (a), decelerating the rotation speed of the substrate until a start of (C), wherein a deceleration in (b) is lower than an acceleration in (a).

A substrate processing method includes supplying a developing liquid configured to form a resist pattern onto a surface of a substrate on which a resist film is formed; performing multiple cycles of a cleaning processing of supplying a modifying liquid containing a modifying agent having a hydrophilic group onto the surface of the substrate on which the resist pattern is formed and supplying a rinse liquid configured to remove the modifying liquid onto the surface of the substrate; and drying the surface of the substrate after performing the multiple cycles of the cleaning processing.

Substrate processing method, recording medium and substrate processing apparatus

A substrate processing method includes supplying a processing liquid to a peripheral edge of a surface of a substrate to form a processing film on the peripheral edge of the surface of the substrate; and bringing a molding solvent supplied to an inner region than a region of the surface of the substrate to which the processing liquid is supplied, into contact with an interface of the processing liquid that faces a central side of the surface.

Substrate processing method and substrate processing apparatus

A developing treatment method performs a developing treatment on a resist film on a substrate. The method includes: a pattern forming step of forming a resist pattern by supplying a developing solution to the substrate and developing the resist film on the substrate; a coating step of coating the developed substrate with an aqueous solution of a water-soluble polymer; and a rinse step of cleaning the substrate by supplying a rinse solution to the substrate coated with the aqueous solution of the water-soluble polymer.

Developing treatment method, computer storage medium and developing treatment apparatus

When performing a liquid processing on a substrate W being rotated and removing a processing liquid by a cleaning liquid, a cleaning liquid nozzleconfigured to discharge a cleaning liquid slantly with respect to a surface of the substrate W toward a downstream side of a rotational direction of the substrate W and a gas nozzleconfigured to discharge a gas toward a position adjacent to a central portion side of the substrate W when viewed from a liquid arrival position R of the cleaning liquid are moved from the central portion side toward a peripheral portion side. A rotation number of the substrate is varied such that rotation number in a period during which the liquid arrival position R moves in the second region becomes smaller than a maximum rotation number in a period during which the liquid arrival position moves in the first region.

Substrate processing method, substrate processing apparatus and recording medium

A substrate processing method includes supplying a water-soluble polymer solution to a surface of a substrate having, on a surface of the substrate, a resist film on which no pattern is formed, after an immersion exposure process, hydrophilizing a surface of the resist film using the supplied water-soluble polymer solution, supplying, after the hydrophilizing, a cleaning liquid to the surface of the substrate while rotating the substrate to remove the water-soluble polymer solution that has not contributed to the hydrophilizing, and drying the substrate supplied with the cleaning liquid, wherein the water-soluble polymer solution has a pH value that allows an acid concentration in the resist film to fall within a permissible range.
