Patent ID: 7727895

Claim:
A substrate processing method comprising: providing a substrate provided thereon with a photoresist film including a first pattern placing the substrate on a substrate supporting surface of a temperature adjusting plate disposed in a processing chamber; adjusting an actual temperature of the substrate supporting surface to coincide with a target temperature of the substrate supporting surface; supplying an atmosphere containing a solvent including an ability to dissolve a photoresist film, thereby dissolving and deforming the photoresist film including the first pattern to reshape the photoresist film into a second pattern; and performing feedback control of the target temperature of the substrate supporting surface, during reshaping of the photoresist film, wherein the feedback control of the target temperature includes detecting an atmospheric temperature in the processing chamber, comparing the target temperature which is being set at that time with the atmospheric temperature thus detected, and determining the target temperature based on a comparison result such that the target temperature satisfies a condition defined as the atmospheric temperature≦the target temperature≦(the atmospheric temperature+2° C.).
