Classification: CPC H  B | IPC B  H

Claim 0:
1. A substrate processing method comprising:
increasing a temperature of a substrate by supplying a heated liquid directly to a second surface of a substrate that is an opposite surface to a first surface of the substrate to heat the substrate;
after the increasing the temperature of the substrate, forming a liquid film of a pre-wetting liquid on the first surface of the substrate by supplying the pre-wetting liquid to the first surface of the substrate while heating and rotating the substrate at a first rotational speed;
after the forming the liquid film, processing the first surface of the substrate with a chemical liquid by supplying the chemical liquid to the first surface of the substrate while heating and rotating the substrate at a second rotational speed that is lower than the first rotational speed; and
after the processing the first surface of the substrate, decreasing the temperature of the substrate,
wherein the heated liquid is discarded through a drain line until a temperature of the heated liquid reaches a predetermined value, and
when the heated liquid reaches the predetermined value, the heated liquid is supplied to the second surface of the substrate in the increasing the temperature of the substrate.
