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 4):
The method of  claim 1 , wherein after repeatedly executing the first etching step a plurality of times, the second etching step is executed.
