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 10):
The apparatus of  claim 9 , further comprising:\n a temperature adjusting part configured to adjust a temperature of the substrate mounted on the mounting table, wherein the control part is configured to, in the second etching step, sublimate and remove the product by controlling an operation of the temperature adjusting part.
