    摘要: A method for removing water molecules from a vacuum chamber for carrying out a process on a target object in vacuum includes the steps of introducing into the vacuum chamber a water molecule removal gas including at least a reduction gas which reduces the water molecules to produce hydrogen molecules and a halogen-based gas which reacts with the produced hydrogen molecules to produce acid, exhausting gases in the vacuum chamber measuring an amount of water molecules present inside the vacuum chamber, and determining whether or not the measured amount of water molecules is greater than or equal to a threshold value, wherein if the measured amount of water molecules is greater than or equal to the threshold value, the water molecule removal gas is introduced into the vacuum chamber in the introducing step.

    摘要: To clean an element in a vacuum chamber by causing particles sticking to the element to scatter, the present invention uses a means for applying a voltage to the element and causing the particles to scatter by utilizing Maxwell's stress, a means for electrically charging the particles and causing the particles to scatter by utilizing the Coulomb force, a means for introducing a gas into the vacuum chamber and causing the particles sticking to the element to scatter by causing a gas shock wave to hit the element, a means for heating the element and causing the particles to scatter by utilizing the thermal stress and thermophoretic force, or a means for causing the particles to scatter by applying mechanical vibrations to the element. The thus scattered particles are removed by carrying them in a gas flow in a relatively high pressure atmosphere.
