Claim 17:
18. A method of manufacturing a semiconductor device comprising:
forming a film containing a predetermined element on a substrate at least by (a) supplying a first process gas containing the predetermined element to the substrate accommodated in a process chamber,
wherein (a) comprises:
(a-1) supplying the first process gas to the substrate through a first gas supply port, the first process gas in (a-1) being supplied from an outer periphery of the substrate toward a center of the substrate; and
(a-2) supplying the first process gas to the substrate through a second gas supply port, the first process gas in (a-2) being supplied from the outer periphery of the substrate along a direction more inclined toward the outer periphery of the substrate than a direction from the outer periphery of the substrate toward the center of the substrate, the first process gas in at least one of (a-1) and (a-2) being temporarily stored in a storage part to be supplied to at least one of the first gas supply port and the second gas supply port.
