Abstract:
1. A film forming method comprising: arranging a target substrate to be processed in a chamber; supplying a processing gas including a chlorine containing gas through a supply path to the chamber in which the target substrate is arranged; arranging a Ti containing unit in the supply path of the processing gas and making a reaction between the chlorine containing gas of the processing gas and Ti of the Ti containing unit by bringing the chlorine containing gas into contact with the Ti containing unit, when the processing gas is supplied to the chamber; and depositing Ti on a surface of the target substrate by a thermal reaction by supplying to the target substrate a Ti precursor gas produced by the reaction between the chlorine containing gas and Ti of the Ti containing unit while heating the target substrate provided in the chamber, wherein the supply path includes a gas line through which the processing gas is supplied from a gas supply source and a gas introduction mechanism for introducing the processing gas supplied through the gas line into the chamber, and the Ti containing unit is arranged in the gas line or the gas introduction mechanism, and wherein, after the depositing of Ti on the surface of the target substrate by the thermal reaction, Ti is further deposited while generating a plasma of the processing gas in the chamber.
