Patent ID: 7693597

Claim:
A computer-readable storage medium storing program instructions for execution by a computer used in a substrate processing apparatus that comprises a chamber equipped with a heating mechanism and configured to house a substrate having a resist film formed thereon, a water vapor supply section configured to supply water vapor into the chamber, an ozone supply section configured to supply ozone into the chamber, a liquid process section configured to supply a prescribed process liquid onto the substrate to carry out a liquid processing, and a control section including the computer and configured to control an operation of the apparatus, wherein the program instructions, when executed by the computer, cause the computer to execute a substrate processing method for removing the resist film from the substrate in the substrate processing apparatus, the method comprising: denaturing the resist film by maintaining an inner region of the chamber, which houses the substrate having the resist film formed thereon, at a prescribed temperature and supplying ozone and water vapor into the chamber in such a manner that the ozone is supplied into the chamber at a ratio being adjusted relative to the water vapor while the water vapor is supplied into the chamber at a prescribed flow rate, and an exhaust flow rate from the chamber is adjusted, such that the dew formation within the chamber is prevented; and then, processing the substrate by use of the prescribed process liquid, thereby removing the denatured resist film from the substrate.
