Abstract
Present disclosure provides a substrate processing apparatus, including a rotatable pedestal configured to hold a substrate, a driving mechanism connected to the rotatable pedestal, a liquid pouring nozzle over the pedestal, a temperature sensor configured to probe a temperature of the substrate processing apparatus, and a controller communicating with the temperature sensor and the driving mechanism. Present disclosure also provides a method for processing a substrate, including providing a substrate on a pedestal of a processing chamber, probing a temperature of the processing chamber, calculating a temperature difference between the temperature of the processing chamber and a predetermined temperature, and determining a rotational speed difference with respect to a predetermined rotational speed of the pedestal according to the temperature difference.
