Abstract:
In a substrate processing method for etching a silicon oxide layer formed on a surface of a substrate, a surface of the silicon oxide layer is hydrophilized. Then, the silicon oxide layer is etched by supplying a halogen-containing gas to the substrate and sublimating a reaction product generated by reaction between the halogen-containing gas and the silicon oxide layer.

Claim (Index 2):
The substrate processing method of  claim 1 , wherein the first step is a step of supplying active species of oxygen to the surface of the silicon oxide layer.
