The embodiments herein relate to methods for processing a wafer through a semiconductor wafer processing system and an apparatus. According to an aspect of the present disclosure, a system for processing a semiconductor wafer is provided. The system includes a heating system, a pressure control system, and a gas flow system. The heating system is configured for heating a chuck. The pressure control system is configured for setting an internal chamber pressure. The gas flow system is configured for inflowing a gas in the process chamber to increase the internal chamber pressure to at least a base pressure. The heating system heats the chuck after the internal chamber pressure reaches the base pressure set by the pressure control system.
