Claim 10:
11. A film deposition method, comprising:
placing a substrate on each of stages arranged along a rotation direction of a rotary table provided in a vacuum chamber; and
intermittently rotating the rotary table and thereby repeating a cycle multiple times, the cycle including
supplying a process gas toward an upper surface of the substrate,
heat-treating the substrate onto which the process gas is supplied at a temperature higher than a temperature used in the supplying of the process gas, and
cooling the heat-treated substrate by using a first cooler disposed above the upper surface of the rotary table and a second cooler disposed below a lower surface of the rotary table,

wherein the first cooler includes an inner shower head, a middle shower head, and an outer shower head that are disposed to respectively correspond to a central part, a middle part, and an outer part of the substrate,
wherein the second cooler includes an inner plate, a middle plate, and an outer plate that are disposed to respectively correspond to the central part, the middle part, and the outer part of the substrate,
wherein the second cooler is provided below the stages and provided spaced apart from the stages, the second cooler being fixed to the vacuum chamber, and
wherein a physical space is present between an entirety of the second cooler and the stages.
