Abstract:
There is provided a substrate processing method, including: forming a silicon nitride film laminated on an etching target film by supplying a film forming gas to a substrate; oxidizing a surface of the silicon nitride film to form an oxide layer by supplying an oxidizing gas to the substrate; and etching the etching target film by supplying an etching gas containing halogen to the substrate, in a state in which the etching target film and the oxide layer are exposed on a surface of the substrate.

Claim (Index 7):
A substrate processing apparatus for executing the substrate processing method of  claim 1 , comprising:\n a rotary table installed in a vacuum container and configured to mount and rotate a substrate; a raw material gas supply part configured to supply a silicon-containing raw material gas as the film forming gas to a first region on the rotary table; a nitriding gas supply part configured to supply a nitriding gas for nitriding the raw material gas and generating a silicon nitride to a second region spaced apart from the first region in a rotation direction of the rotary table on the rotary table; a separation mechanism configured to separate an atmosphere of the first region from an atmosphere of the second region; an oxidizing gas supply part configured to supply the oxidizing gas onto the rotary table; and a controller configured to output a control signal so that the oxidizing gas is supplied onto the rotary table after the substrate has repeatedly passed through the first region and the second region a plurality of times in a state in which the raw material gas and the nitriding gas are supplied onto the rotary table.
