  • Publication number: 20080245389
    Abstract: 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.

  • Patent number: 7299104
    Abstract: Shock waves occurring when opening a gate valve between two vacuum chambers and peeling of particles by a viscous force taking place when a gas is supplied into a vacuum chamber are necessary to be suppressed by the apparatus and method of the invention, whereby contamination of a substrate by particles is suppressed. If one vacuum chamber is a substrate processing chamber for performing a vacuum process on the substrate and the other chamber is a transfer chamber having a substrate transfer device therein, the gate valve is opened when inner pressures of both the vacuum chambers are less than 66.5 Pa and higher one thereof is less than twice a lower one thereof. Preferably, a purge gas for peeling of particles is supplied, before supplying the purge gas for pressure control, into the substrate processing chamber with a flow rate greater than that of the purge gas for pressure control.
