摘要: In some embodiments, the invention includes a cylindrical cathode target assembly for use in sputtering target material onto a substrate that comprises a generally cylindrical target, mean for rotating the target about its axis during a sputtering operation, an elongated magnet carried within the target for generation of a plasma-containing magnetic field exterior to but adjacent the target, a framework for supporting the magnet against rotation within the target, and a power train for causing the magnet to oscillate within and axially of the target in a substantially asynchronous manner to promote generally uniform target utilization along its length, as well as its method of use. In some embodiments, the magnet is oscillated in response to rotation of the target.

摘要: A dipole ion source (Figure 1) includes two cathode surfaces, a substrate (1) and a pole (3); wherein a gap is defined between the substrate and the pole; an unsymmetrical mirror magnetic field including a compressed end, wherein the substrate is positioned in the less compressed end of the magnetic field; and an anode (4) creating an electric field penetrating the magnetic field and confining electrons in a continuous Hall current loop, wherein the unsymmetrical magnetic field serves an ion beam on the substrate.

摘要: The preferred embodiments described herein provide a magnetic mirror plasma source. While the traditional magnetic/electrostatic confinement method is ideal for many applications, some processes are not best served with this arrangement. The preferred embodiments described herein present a new technique to confine electrons (3) to produce a low pressure, dense plasma directly on a substrate surface (75). With these preferred embodiments, a combination of electrostatic and mirror magnetic confinement is implemented. The result is a novel plasma source that has unique and important advantages enabling advancements in PECVD, etching, and plasma treatment processes.

摘要: The preferred embodiments described herein provide a Penning discharge plasma source. The magnetic and electric field arrangement, similar to a Penning discharge, effectively traps the electron Hall current in a region between two surfaces. When a substrate (10) is positioned proximal to at least one of the electrodes (11, 12) and is moved relative to the plasma, the substrate (10) is plasma treated, coated or otherwise modified depending upon the process gas used and the process pressure. This confinement arrangement produces dramatic results not resembling known prior art. Using this new source, many applications for PECVD, plasma etching, plasma treating, sputtering or other plasma processes will be substantial improved or made possible. In particular, applications using flexible webs (10) are benefited.
