  • Publication number: 20220259732
    Abstract: A film formation method for forming a CVD film and an ALD film on a film formation target. In an ALD process, an ALD cycle is repeatedly executed a plurality of times, the ALD cycle including: a first step for filling a reaction container with a source gas introduced through a first supply pipe; a second step for exhausting the source gas from the reaction container; a third step for filling the reaction container with a reactant gas activated by an inductively coupled plasma in a second supply pipe and introduced through the second supply pipe; and a fourth step for exhausting the reactant gas from the reaction container. In a CVD process, the ALD cycle is executed at least once, and the second step is finished while leaving the source gas in a gas phase in the reaction container.
