Abstract:
A method for controlling a substrate temperature in a substrate processing system includes determining a temperature difference between the substrate temperature before the substrate is loaded onto a substrate support device and a desired temperature for the substrate support device and, during a first period, controlling a thermal control element to adjust the temperature of the substrate support device to a temperature value based on the temperature difference. The temperature value is not equal to the desired temperature for the substrate support device. The method further includes loading the substrate onto the substrate support device after the first period begins and before the temperature of the substrate support device returns to the desired temperature and, during a second period that follows the first period, controlling the temperature of the substrate support device to the desired temperature for the substrate support device.
