Abstract

A liquid processing method is provided for performing a liquid process on a front surface of a substrate by using a processing solution and then performing a rinse process on the front surface of the substrate by using a rinse solution having a temperature lower than a temperature of the processing solution. The method includes performing an intermediate process between the liquid process and the rinse process, for adjusting a temperature of the front surface of the substrate to a temperature higher than the temperature of the rinse solution and lower than the temperature of the processing solution. In the intermediate process, an intermediate processing solution having a temperature higher than the temperature of the rinse solution and lower than the temperature of the processing solution is supplied only to a rear surface of the substrate.
