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 4):
The method of  claim 1 ,\n wherein the processing vessel is provided with a first gas inlet opening and a second gas inlet opening, the first gas inlet opening is provided above the target object, the second gas inlet opening is provided at a side of the target object, in (a), the first gas is supplied into the processing vessel from the first gas inlet opening and a backflow prevention gas is supplied into the processing vessel from the second gas inlet opening, in (a), the second gas is supplied into the processing vessel from the second gas inlet opening and the backflow prevention gas is supplied into the processing vessel from the first gas inlet opening, in (b), the third gas is supplied into the processing vessel from the first gas inlet opening and the backflow prevention gas is supplied into the processing vessel from the second gas inlet opening, and a pipeline connected to the first gas inlet opening and a pipeline connected to the second gas inlet opening are not intersected with each other.
