摘要： An antenna includes branches having substantially identical shapes. The branches are symmetrically disposed about a central point and extend along at least two concentric patterns whose geometric centers coincide with the central point. The branches each include pattern-forming portions that lie entirely within the concentric patterns, and at least one connecting portion extending between and connecting the pattern-forming portions. Input/output terminals for allowing a voltage to be impressed across the branches are provided at ends of each of the branches.

摘要： An electron cyclotron resonance equipment generates plasma by application of a processing gas and microwave energy into a vacuum chamber having a wafer therein in an environment of reduced pressure. The equipment includes a horn antenna assembly mounted onto an uppermost end of the vacuum chamber for radiating the microwave energy supplied from a high-frequency generator into the vacuum chamber. The horn antenna enables extension and retraction in a lengthwise direction to change a flare angle of the horn antenna. The equipment is provided with a fixed antenna and a plurality of mobile antennas to configure a horn antenna assembly, thereby enabling control of the flare angle in the horn antenna as a result of displacement of the mobile antennas. Thus, the uniformity in radiation of the microwave energy within plasma chamber can be controlled with efficiency.

摘要： A sputtering apparatus includes a sputtering chamber, a target disposed in the sputtering chamber, and a magnetic field generator for generating a rotating magnetic field at the front of the target. The magnetic field generator includes a main magnetic field-generating part that faces the back of the target and is horizontally (laterally) offset from a vertical line passing through the center of the target. A magnetic annulus of the main magnetic field-generating part forms a magnetic enclosure having openings therethrough at locations faced in the directions of the central and peripheral portions of the target. The magnetic field-generating part thus produces a magnetic field having a non-uniform distribution at the front of the target. A substrate is positioned within the sputtering chamber facing the front of the target. A metal layer is formed by sputtering atoms from the front of the target onto the substrate. The behavior of the sputtered atoms can be effectively controlled by the magnetic field.
