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.
