  • Patent number: 10096463
    Abstract: A method of manufacturing a semiconductor device includes: forming a film on a substrate by performing a cycle a predetermined number of times. The cycle includes non-simultaneously performing: supplying a precursor from a first nozzle to a substrate and exhausting the precursor from an exhaust port; supplying a first reactant from a second nozzle to the substrate and exhausting the first reactant from the exhaust port; and supplying a second reactant from a third nozzle to the substrate and exhausting the second reactant from the exhaust port. A substrate in-plane film thickness distribution of the film formed on the substrate is controlled by controlling a balance between a flow rate of an inert gas supplied from the second nozzle, a flow rate of an inert gas supplied from the third nozzle, and a flow rate of an inert gas supplied from the first nozzle in supplying the precursor.
