Provided are a semiconductor manufacturing apparatus and a substrate processing method that can reduce a temperature difference along the circumference of a substrate and continue substrate processing even when a temperature sensor becomes defective. The semiconductor manufacturing apparatus includes a reaction tube configured to process a wafer, a heater configured to heat the reaction tube, an exhaust pipe, a control unit configured to control a cooling gas exhaust device, the heater, and a pressure sensor that detects a pressure inside the exhaust pipe when cooling gas flows through the exhaust pipe. The control unit previously acquires an average value of second temperature detecting units that detect states of a peripheral part of a wafer, and a measure value of a first temperature detecting unit that detects a state of a center part of the wafer so as to control the heat and the cooling device based on the acquired values.
