A semiconductor manufacturing apparatus and substrate processing method is provided with which the film formed on a substrate can be controlled in thickness and quality. The substrate processing method includes a step of acquiring a measurement value based on a first detecting section for detecting a state of a peripheral edge of a substrate and a measurement value based on a second detecting section for detecting a state of a center of the substrate and determining a first difference between the measurement value based on the first detecting section and the measurement value based on the second detecting section, comparing between a previously stored second difference between a measurement value concerning the first detecting section and a measurement value concerning the second detecting section with the first difference between the measurement value based on the first detecting section and the measurement value based on the second detecting section, calculating a correction value for a pressure in a cooling-gas passage provided between a process chamber for processing the substrate and a heating device depending upon the first difference when the first difference is different from the second difference, and correcting the pressure value based on the pressure correction value, and a step of processing the substrate by flowing a cooling gas through the cooling-gas passage by means of a cooling device while heating the process chamber by the heating device, and placing the heating device and the cooling device under control of a control section depending upon a pressure value corrected.
