Claim 0:
1. A film deposition apparatus, comprising:
a rotary table disposed in a vacuum chamber;
multiple stages on each of which a substrate is placeable, the stages being arranged along a circumferential direction of the rotary table;
a process area configured to supply a process gas toward an upper surface of the rotary table;
a heat treatment area that is disposed apart from the process area in the circumferential direction of the rotary table and configured to heat-treat the substrate at a temperature higher than a temperature used in the process area;
a cooling area that is disposed apart from the heat treatment area in the circumferential direction of the rotary table and configured to cool the substrate,
a first cooler disposed in the cooling area above the upper surface of the rotary table; and
a second cooler disposed in the cooling area 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 located in the cooling area, the central part being formed in a circle shape, and each of the middle part and the outer part being formed in an annular shape,
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 located in the cooling area,
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.
