Claim 21:
22. A method for manufacturing a semiconductor device by using a vaporizer comprising:
a vaporization chamber comprising a first portion and a second portion;
a first fluid supply part connected to the first portion of the vaporization chamber, and configured to supply a mixed fluid in which a first carrier gas and a liquid precursor are mixed, toward the second portion; and
a second fluid supply part configured to supply a second carrier gas such that a part of the second carrier gas is supplied in a first direction toward the first portion and another part of the second carrier gas is supplied in a second direction, which is different from the first direction, to flow the second carrier gas in the second direction along a sidewall of the vaporization chamber,
the method comprising:
supplying a vaporized gas obtained by vaporizing the liquid precursor by the vaporizer to a process chamber that accommodates a substrate by the first fluid supply part; and
supplying the second carrier gas by the second fluid supply part.
