  • Publication number: 20160118291
    Abstract: Wafer carriers and methods for moving wafers in a reactor. The wafer carrier may include a platen with a plurality of compartments and a plurality of wafer platforms. The platen is configured to rotate about a first axis. Each of the wafer platforms is associated with one of the compartments and is configured to rotate about a respective second axis relative to the respective compartment. The platen and the wafer platforms rotate with different angular velocities to create planetary motion therebetween. The method may include rotating a platen about a first axis of rotation. The method further includes rotating each of a plurality of wafer platforms carried on the platen and carrying the wafers about a respective second axis of rotation and with a different angular velocity than the platen to create planetary motion therebetween.

  • Publication number: 20120223048
    Abstract: An inline processing system for patterning magnetic recording layers on hard discs for use in a hard disc drive. Discs are processed on both sides simultaneously in a vertical orientation, in round plate-like holders called MDCs. A plurality (as many as 10) discs are held in a dial carrier of the MDC, and transferred from one process station to another. The dial carrier of the MDC may be rotated and/or angled at up to 70° from normal in each process station, so that one or a plurality of process sources may treat the discs simultaneously. This configuration provides time savings and a reduction in the number and size of process sources needed. A mask enhancement process for patterning of magnetic media, and a filling and planarizing process used therewith, are also disclosed.

  • Publication number: 20070283709
    Abstract: Apparatus and methods for improving the control of the temperature of a supported member, such as a substrate, in high vacuum processing systems, such as ion beam etch (IBE) systems. The apparatus includes thermoelectric devices that transfer heat from a support member supporting the supported member to a liquid-cooled heat exchange member to regulate the temperature of the support member. The method includes cooling the support member with thermoelectric devices that transfer the heat to the liquid-cooled heat exchange member.

  • Patent number: 7183716
    Abstract: A charged particle source utilizes a novel plasma processing chamber, RF coil and ion optics, to achieve high uniformity. The plasma processing chamber has a re-entrant vessel which is movable, and which includes extensions of adjustable shape or position, to make more uniform the plasma contained within the chamber. One or more magnets, which may be static or moving, may be included within the re-entrant vessel. The ion optics include a grid with a number of apertures, and tuning features each surrounding an aperture. These tuning features either reduce the diameter of the associated aperture, or increase the length of that aperture, to create more uniform beamlets emerging from the grid. The RF coil includes a flux concentrator positioned adjacent to the winding in at least one angular region thereof to tune the magnetic field produced thereby.
