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 1):
A substrate treatment method for at least partially removing a processing target film formed on a surface of a substrate, comprising:\n 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, wherein the second etching step includes:\n an adsorption step of causing molecules of a first processing gas to be adsorbed onto the processing target film subjected to the first etching; \n a production step of producing a first product by supplying a second processing gas toward the processing target film onto which the molecules of the first processing gas are adsorbed, and allowing the processing target film, the first processing gas and the second processing gas to react with each other; and \n a first removal step of sublimating and removing the first product.
