Abstract:
A method includes anisotropically etching an etching target layer of a target object through an opening of the target object by generating plasma of a first gas within a processing vessel in which the target object is accommodated; and then forming a film on an inner surface of the opening by repeating a sequence comprising: a first process of supplying a second gas into the processing vessel; a second process of purging a space within the processing vessel; a third process of generating plasma of a third gas containing an oxygen atom within the processing vessel; and a fourth process of purging the space within the processing vessel. The first gas contains a carbon atom and a fluorine atom. The second gas contains an aminosilane-based gas. The etching target layer is a hydrophilic insulating layer containing silicon. Plasma of the first gas is not generated in the first process.

Claim (Index 1):
A method of processing a target object, the method comprising:\n providing, in a processing vessel, the target object having an etching target layer and a mask provided on the etching target layer, the mask being provided with an opening reaching the etching target layer; (a) etching the etching target layer through the opening using a plasma generated from a first gas containing a carbon atom and a fluorine atom to form a first film on an upper area of the opening; and (b) forming a second film on an area other than the upper area of the opening where the first film is not formed, wherein (b) includes: (i) exposing the target object to a second gas containing a non-plasma organic-containing aminosilane-based gas to form a precursor layer, and (ii) generating plasma from a third gas containing modification gas to modify the precursor layer.
