Claim Text:
1. A substrate processing apparatus comprising: a processing chamber configured to process a substrate; a substrate support disposed in the processing chamber; a first heater and a second heater accommodated in the substrate support and configured to heat the substrate, the first heater being disposed closer to an outer periphery of the substrate support than the second heater; a shaft supporting the substrate support; a first wire inserted through the shaft, the first wire comprising a first input-side heater power supply line, a first output-side heater power supply line, a first input-side connection mechanism, a first output-side connection mechanism, a first input-side heater wire having a first end connected to an input terminal of the first heater and a second end connected to the first input-side heater power supply line via the first input-side connection mechanism and a first output-side heater wire having a first end connected to an output terminal of the first heater and a second end connected to the first output-side heater power supply line via the first output-side connection mechanism; a second wire inserted through the shaft, the second wire comprising a second input-side heater power supply line, a second output-side heater power supply line, a second input-side connection mechanism, a second output-side connection mechanism, a second input-side heater wire having a first end connected to an input terminal of the second heater and a second end connected to the second input-side heater power supply line via the second connection mechanism and a second output-side heater wire having a first end connected to an output terminal of the second heater and a second end connected to the second output-side heater power supply line via the second output-side connection mechanism; a supporting unit holding the first input-side connection mechanism, the first output-side connection mechanism, the second input-side connection mechanism, and the second output-side connection mechanism, the supporting unit comprising: a gas supply mechanism installed between the inner wall of the shaft and the plate-shaped first partition wherein a distance between the gas supply mechanism and the both of the first input-side connection mechanism and the first output-side connection mechanism is shorter than a distance between the gas supply mechanism and the both of the second input-side connection mechanism and the second output-side connection mechanism, wherein a gas supplied from the gas supply mechanism flows through the gap between the first partition and the inner wall of the shaft and the gap between the second partition and the inner wall of the shaft; and a temperature detector connected to the supporting unit and configured to detect a temperature of the supporting unit.
