Abstract:
A protective film forming method is provided. In the method, substantially an entire surface of a silicon-containing underfilm is terminated with fluorine by supplying a fluorine-containing gas to the silicon-containing underfilm formed on a substrate having a surface including a plurality of recesses and a flat surface provided between the adjacent recesses. A surface of the silicon-containing underfilm formed on the flat surface of the substrate is nitrided by supplying a nitriding gas converted to plasma to the silicon-containing underfilm terminated with fluorine such that a silicon adsorption site is formed on the surface of the silicon-containing underfilm formed on the flat surface of the substrate. A silicon-containing gas is adsorbed on the silicon adsorption site by supplying the silicon-containing gas to the silicon-containing underfilm.

Claim (Index 10):
The protective film forming method according to  claim 1 ,\n wherein the substrate is arranged on a turntable along a circumferential direction thereof, wherein a fluorine-containing gas supply region configured to supply the fluorine-containing gas to the substrate, a silicon-containing gas supply region configured to supply the silicon-containing gas to the substrate, and a nitriding gas supply region configured to supply the nitriding gas to the substrate are arranged above the turntable, along the circumferential direction, and apart from each other, wherein the step of causing substantially the entire surface of the silicon-containing underfilm to be terminated with fluorine is performed by stopping the supply of the silicon-containing gas in the silicon-containing gas supply region and the supply of the nitriding gas in the nitriding gas supply region and supplying the fluorine-containing gas to the substrate in the fluorine-containing gas supply region while rotating the turntable at least one time, wherein the step of nitriding the surface of the silicon-containing underfilm is performed by stopping the supply of the fluorine-containing gas in the fluorine-containing gas supply region and supplying the nitriding gas converted to the plasma in the nitriding gas supply region while rotating the turntable a plurality of times, and wherein the step of adsorbing the silicon-containing gas on the silicon adsorption site is performed by stopping the supply of the fluorine-containing gas in the fluorine-containing gas supply region and supplying the silicon-containing gas to the substrate in the silicon-containing gas supply region while rotating the turntable a plurality of times.
