A substrate processing method includes (A) to (C) described below. (A) A substrate having a surface in which a SiO film and a Low-k film or a SiN film are exposed is preprared. The Low-k film or the SiN film is exposed to oxygen plasma. (B) A protective film is formed on the Low-k film or the SiN film by supplying an organic compound (self-assembled monolayer (SAM) material) configured to form a SAM to the surface of the substrate. (C) The SiO film is etched by supplying hydrofluoric acid to the surface of the substrate while inhibiting etching of the Low-k film or the SiN film caused by the hydrofluoric acid with the protective film.

Substrate processing method and substrate processing apparatus

A substrate processing method includes holding a substrate; and supplying an etching liquid to the substrate held in the holding of the substrate. The etching liquid contains an etching agent configured to etch a metal-based first material and a silicon-based second material exposed on the substrate and a protection agent configured to react with the second material between the first material and the second material to form a protection layer on a surface of the second material. Here, the etching agent is a liquid which contains fluorine atoms and an organic solvent and substantially does not contain water, and the protection layer protects the second material from etching with the etching agent.

Substrate processing device and etching liquid

A method of processing a substrate includes loading the substrate to which a processing liquid is adhered, inside a processing container, removing the processing liquid adhering to the substrate by supplying a first organic solvent to the loaded substrate, causing the substrate to be water-repellent by supplying a water repellent to the substrate from which the processing liquid has been removed, supplying a second organic solvent to the water-repellent substrate, and drying the substrate by volatilizing the second organic solvent adhering to the substrate.

In a template treatment of forming a film of a release agent on a treatment surface of a template, the treatment surface of the template is first cleaned. Thereafter, in a coating unit, the release agent is applied to the treatment surface of the template. The release agent on the template is then dried. Then, alcohol is applied to the release agent on the template to make the release agent adhere to the treatment surface of the template and to remove an unreacted portion of the release agent. Thereafter, the alcohol on the template is dried and removed. In this manner, a film of the release agent is formed in a predetermined film thickness on the treatment surface of the template.

The present invention provides a method for applying an application liquid between a template and a substrate, and transferring the transfer pattern onto the application liquid. The template is inclinedly arranged with respect to the substrate in a manner that a first distance between a first end portion of the template and the substrate is a distance that causes a capillary action of the application liquid to occur, and a second distance between a second end portion of the template that opposes the first end portion and the substrate is a distance that does not cause the capillary action of the application liquid to occur. Thereafter, the application liquid is supplied from an outer side of the first end portion to the first end portion. Thereafter, the second end portion and the substrate are relatively moved so that the second distance becomes equal to the first distance.
