Abstract:
A substrate treatment method capable of obtaining a flat processing target film. Molecules of an HF gas are adsorbed onto a corner SiO 2  layer remaining in a corner portion of a groove of a wafer subjected to an oxide film removal process. An excess HF gas is discharged. An NH 3  gas is supplied toward the corner SiO 2  layer onto which the molecules of the HF gas are adsorbed. AFS is formed by reacting the corner SiO 2  layer, the HF gas and the NH 3  gas with each other. The AFS is sublimated and removed.

Claim (Index 9):
A substrate treatment apparatus, comprising:\n a mounting table configured to mount a substrate having a processing target film formed thereon; a processing chamber configured to accommodate the mounting table; a processing gas supply part configured to supply a first processing gas and a second processing gas into the processing chamber; and a control part configured to control an operation of the processing gas supply part, wherein, if the substrate is mounted on the mounting table, the control part executes a first etching step of subjecting the processing target film to a first etching and a second etching step of subjecting the processing target film subjected to the first etching to a second etching, and the control part controls the operation of the processing gas supply part in the second etching step so that molecules of the first processing gas are adsorbed onto the processing target film subjected to the first etching, the second processing gas is supplied toward the processing target film onto which the molecules of the first processing gas are adsorbed, and the processing target film, the first processing gas and the second processing gas react with each other to produce a product.
