  • Patent number: 10665944
    Abstract: An antenna device includes a core, a bobbin member having a partition, and a coil provided around the bobbin member. The coil is configured with a tight winding portion and a loose winding portion. The tight winding portion is provided between one bobbin side and the partition. The loose winding portion is provided between the other bobbin side and the partition. The loose winding portion is configured with a first winding layer and a second winding layer. A wire winding direction of the first winding layer is opposite to a wire winding direction of the second winding layer so that the wire of the first winding layer and the wire of the second winding layer cross and overlap to each other along part of the bobbin member.

    Abstract: In a plasma processing apparatus, a table has a wafer support to hold a wafer and a peripheral segment surrounding the wafer support and having through-holes. The peripheral segment has an upper surface lower than that of the wafer support. An outer focus ring is disposed over the peripheral segment and has a recess or a cutout at an inner portion of the outer focus ring, and the recess or cutout has through-holes. An inner focus ring is disposed in the recess or cutout of the outer focus ring. Lift pins respectively extend through the through-holes of the peripheral segment and the through-holes of the recess or cutout of the outer focus ring. Shift mechanisms control shift of the respective lift pins.
