Abstract:
A method for depositing a silicon nitride film is provided to fill a recessed pattern formed in a surface of a substrate. In the method, a first adsorption blocking region is formed by adsorbing first chlorine radicals such that an amount of adsorption increases upward from a bottom portion of the recessed pattern. A source gas that contains silicon and chlorine adsorbs on an adsorption site where the first adsorption site is not formed. A molecular layer of a silicon nitride film is deposited so as to have a V-shaped cross section. A second adsorption blocking region is formed by adsorbing second chlorine radicals on the molecular layer of the silicon nitride film. The molecular layer of the silicon nitride film is modified by nitriding the molecular layer while removing the second adsorption blocking region.

Claim (Index 13):
A film deposition apparatus, comprising:\n a chamber; a turntable provided in the chamber and having a substrate receiving region to receive a substrate formed in a surface thereof; a chlorine radical supply region provided above the turntable and in a predetermined region along a rotational direction of the turntable and capable of supplying chlorine radicals to the surface of the turntable; a source gas supply region provided above the turntable and downstream of the chlorine radical supply region in the rotational direction of the turntable and capable of supplying a source gas that contains silicon and chlorine to the surface of the turntable; a nitriding gas supply region provided above the turntable and downstream of the source gas supply region and capable of supplying an activated nitriding gas to the surface of the turntable; and a controller configured to alternately perform a film deposition process by supplying the chlorine radicals to the turntable in the chlorine radical supply region, supplying the source gas to the turntable in the source gas supply region, and supplying the activated nitriding gas to the turntable in the nitriding region while rotating the turntable one time, and a modification process by supplying the chlorine radicals to the turntable in the chlorine radical supply region, and the activated nitriding gas to the turntable in the nitriding region and stopping supply of the source gas in the source gas supply region while rotating the turntable a predetermined number of times of one or more.
