  • 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.

  • Patent number: 10413946
    Abstract: Embodiments of the inventive concepts provide a method of cleaning a furnace-type semiconductor apparatus that is equipped in a clean room and includes a process chamber in which a process of forming a thin film is performed on a substrate. The method includes supplying air of the clean room into the process chamber after the process of forming the thin film, and thermally treating an inside of the process chamber using the air of the clean room supplied to the inside of the process chamber. An adhered material containing chlorine is formed on an inner surface of the process chamber by the process of forming the thin film, and the chlorine of the adhered material is removed by the thermal treatment of the inside of the process chamber.
