  • Magnetic Precession Based True Random Number Generator
    Publication number: 20100174766
    Abstract: A method and apparatus for generating a random logic bit value. In some embodiments, a spin polarized current is created by flowing a pulse current through a spin polarizing material. The spin polarized current is injected in a free layer of a magnetic tunneling junction and a random logical bit value results from a variation in pulse current duration or a variation in thermal properties.

  • APPARATUS AND METHODS FOR PREVENTING ROTATIONAL SLIPPAGE BETWEEN A VERTICAL SHAFT AND A SUPPORT STRUCTURE FOR A SEMICONDUCTOR WAFER HOLDER
    Publication number: 20070056150
    Abstract: A substrate support assembly positively secures a substrate holder support to a rotation shaft with respect to rotationally applied forces. A substrate holder support is configured to have an opening in a socket into which, when aligned with an indentation in the rotational shaft to form a passage, a retaining member is removably inserted to engage both the socket opening and the shaft indentation. Methods of rotating a substrate while minimizing rotational slippage of the substrate holder support with respect to the shaft are also provided.
