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 7):
The method according to  claim 5 ,\n wherein the substrate is placed on a surface of a turntable along a circumferential direction thereof, the turntable being provided in a chamber, wherein a chlorine radical adsorption region capable of supplying the first chlorine radicals and the second chlorine radicals to the substrate, a first purge region capable of supplying the third purge gas to the substrate, a source gas adsorption region capable of supplying the second source gas to the substrate, a second purge region capable of supplying the fourth purge gas to the substrate, and a nitriding region capable of supplying the activated first nitriding gas and the activated second nitriding gas to the substrate are provided above the turntable and along the circumferential direction of the turntable, wherein the film deposition step is performed by rotating the turntable forming the first adsorption blocking region is performed by rotating the turntable while supplying the first chlorine radicals in the chlorine radical adsorption region, the source gas in the source gas adsorption region, the activated first nitriding gas in the nitriding region, and the first purge gas in the first purge region, and the second purge gas in the second purge region to the substrate, and wherein the modification step is performed by rotating the turntable while supplying the second chlorine radicals in the chlorine radical adsorption region, the activated second nitriding gas in the nitriding region, the first purge gas in the first purge region and the second purge gas in the second purge region, without supplying the source gas in the source gas adsorption region.
