  • Publication number: 20240218511
    Abstract: Disclosed are substrate degassing methods and semiconductor fabrication methods using the same. The substrate degassing method comprises operating a vacuum pump associated with a process chamber to remove gas from the process chamber, preparing a substrate in the process chamber, blocking introduction of gas into the process chamber, and repeatedly opening and closing a pump valve at least two times. The pump valve inhibits the vacuum pump from removing gas from the process chamber when closed and permits the vacuum pump to remove gas from the process chamber when opened. The step of closing the pump valve is performed for a first time period. The step of opening the pump valve is performed for a second time period. The first time period is greater than the second time period.
