Claim 0:
1. A method of forming a metal-containing nitride film containing silicon, the method comprising:
adjusting a temperature of a substrate to a predetermined temperature of 400 degrees C. to 530 degrees C.;
forming a TiSi layer on the substrate by reacting chlorine and silicon to produce SiCl4 and removing the chlorine and the silicon from the substrate by repeating a cycle, the cycle including: alternately supplying a TiCl4 gas and a silicon-containing gas into a processing container in which the substrate is accommodated; and
forming a TiSiN film on the substrate by nitriding the TiSi layer on the substrate by supplying a nitrogen-containing gas to the TiSi layer on the substrate,
wherein a series of processes, in which the cycle is repeated n times and then the supplying the nitrogen-containing gas is executed, is repeated m times in this order (where m is an integer of one or more), and
wherein in the series of processes, if the temperature of the substrate is adjusted to a temperature range of 400 degrees C. or more and less than 430 degrees C., n is set to an integer of 1 or more, and if the temperature of the substrate is adjusted to a temperature range of 430 degrees C. or more and 530 degrees C. or less, n is set to an integer of two or more.
