Claim 17:
18. A substrate treatment device, comprising:
a flow path configured to flow a refrigerant:
a condenser provided in the flow path:
a heat exchanger provided in the flow path:
a compressor provided in the flow path between the condenser and the heat exchanger:
a cooler cooling the refrigerant flowing from the condenser into the heat exchanger:
a gas cooling part supplying a gas to the heat exchanger:
the heat exchanger configured to cool the gas by exchanging heat exchange between the refrigerant and the gas,
a first thermometer configured to detect a temperature of the cooled gas by the gas cooling part:
a second thermometer configured to detect a temperature of the refrigerant flowing into the heat exchanger: and
a first controller configured to control the temperature of the cooled refrigerant by the cooler, the refrigerant flowing into the heat exchanger,
the first controller controlling the temperature of the cooled refrigerant flowing into the heat exchanger by switching a first control and a second control, the first control being based on the temperature detected by the first thermometer, the second control being based on the temperature detected by the second thermometer,
a placement part configured to place a substrate and rotate;
a liquid supplier configured to supply a liquid on a surface of the substrate, the surface being cleaned;
a cooling gas supplier configured to supply a gas to a surface of the substrate on a side of the placement part, the gas being cooled by the cooling device; and
a second controller configured to control a rotation speed of the substrate, a supply amount of the liquid, and a first controller of the cooling device.
