    摘要: In a high frequency plasma generation apparatus used in a reactive ion etching apparatus, an ion shower apparatus, a sputter apparatus, etc. for fabricating thin films or semiconductor devices for which fine patterning process is required, electrical breakdown is apt to be provoked at the surface of a high frequency coil (8), because the high frequency coil (8) is usually inserted in a plasma. In order to remove this drawback, according to this invention, the high frequency coil (8) is disposed in the plasma production chamber (1) at the neighborhood of the cylindrical side wall (20), and thus a plasma confinment domain (12) is formed inside of this high frequency coil (8) by means of a magnetic field production means (3) which generates a multi-cusp magnetic field so that the plasma confinement domain (12) is separated from the high frequency coil (8). In this way electrical breakdown on the surface of the high frequency coil (8) is prevented and thus the apparatus according to this invention can work stably for a long time.

    摘要: A magnetic mirror machine (200), comprises a first inner coil (104) arranged to carry a current in a first direction; and a second inner coil (105) offset in an axial direction from said first inner coil (104) and arranged to carry a current in a second direction opposite to said first direction. The mirror machine (200) further comprises a first outer coil (210) located radially outside said first inner coil (104) and arranged to carry a current in said second direction; and a second outer coil (212) located radially outside said second inner coil (105) and arranged to carry a current in said first direction.

    摘要: The charged particles comprise electrons and positive ions. A magnetic field having only point cusps is used to confine injected electrons and so to generate a negative potential well (600). Positive ions injected into the negative potential well are trapped therein. The preferred means for generating the magnetic field is current-carrying elements (800) arranged at positions corresponding to the edges of any of several truncated regular polyhedrons.
