    摘要: A coil shield assembly for an RF field coil in a plasma processing system includes a first shield positioned inside the coil. The first shield has a central opening substantially surrounding a central space of a processing chamber in which the plasma is maintained. At least one slot is formed in the first shield and extends therethrough. A barrier is positioned between the first shield and the coil and spaced apart from the first shield near the at least one slot. The slot permits an RF signal from the coil to couple with the plasma, and the first shield and the barrier are structured and arranged to prevent plasma ions or sputtered material from bombarding the coil by a direct path from the central space and through the at least one slot.

    摘要: A robot having a pair of magnetic couplings that each couple a motor in a cylindrical first chamber to an associated cylindrical ring closely spaced from the cylindrical wall of said first chamber. The robot includes a mechanism to convert rotation of each of these rings into separate motions of the robot. In the preferred embodiment, these separate motions are radial and rotational.
