<p>An inventive substrate treatment method includes a silylation step of supplying a silylation agent to a substrate, and an etching step of supplying an etching agent to the substrate after the silylation step. The method may further include a repeating step of repeating a sequence cycle including the silylation step and the etching step a plurality of times. The cycle may further include a rinsing step of supplying a rinse liquid to the substrate after the etching step. The cycle may further include a UV irradiation step of irradiating the substrate with ultraviolet radiation after the etching step. The method may further include a pre-silylation or post-silylation UV irradiation step of irradiating the substrate with the ultraviolet radiation before or after the silylation step.</p> |
