Abstract: There is provided a technique that includes: forming a film on a substrate in a process chamber by performing a cycle a predetermined number of times, the cycle including non-simultaneously performing: (a) supplying a precursor from a first supplier to the substrate and exhausting the precursor from an exhaust port installed opposite to the first supplier with the substrate interposed between the exhaust port and the first supplier; and (b) supplying a reactant from a second supplier to the substrate and exhausting the reactant from the exhaust port, wherein in (a), inert gas is supplied into the process chamber from a third supplier installed at a region, which is a region on a side of the exhaust port among a plurality of regions partitioned in the process chamber by a bisector perpendicular to straight line connecting the first supplier and the exhaust port in a plane view.

Abstract: A substrate processing apparatus, including: a reaction container in which a substrate is processed; a seal cap, brought into contact with one end in an opening side of the reaction container via a first sealing member and a second sealing member so as to seal the opening of the reaction container air-tightly; a first gas channel, formed in a region between the first sealing member and the second sealing member in a state where the seal cap is in contact with the reaction container; a second gas channel, provided to the seal cap and through which the first gas channel is in communication with an inside of the reaction container; a first gas supply port that is provided to the reaction container and supplies a first gas to the first gas channel; and a second gas supply port that is provided to the reaction container and supplies a second gas into the reaction container, wherein a front end opening of the first gas supply port opening to the first gas channel, and a base opening of the second gas channel openin
