  • Patent number: 9241011
    Abstract: A method and system is provided for assessing the cumulative set of access entitlements to which an entity, of an information system, may be implicitly or explicitly authorized, by virtue of the universe of authorization intent specifications that exist across that information system, or a specified subset thereof, that specify access for that entity or for any entity collectives with which that entity may be directly or transitively affiliated. The effective system-level access granted to the user based upon operating system rules or according to access check methodologies is determined and mapped to administrative tasks to arrive at the cumulative set of access entitlements authorized for the user.
    Type: Grant
    Filed: September 22, 2014
    Date of Patent: January 19, 2016
    Inventor: Sanjay Tandon

  • Patent number: 6855568
    Abstract: Disclosed are methods and apparatus for detecting defects in a partially fabricated semiconductor device with self-aligned contacts. The self-aligned contacts are formed from a first layer with a plurality of contact portions, a second layer with a plurality of conductive lines that are each aligned proximate to an associated underlying contact portion, and a third insulating layer formed over the conductive lines and their proximate underlying contact portions. The third insulating layer has a plurality of vias formed therein that are each formed alongside a one of the conductive lines and over its proximate underlying contact portion. A charged particle beam is scanned over a portion of the vias to form a voltage contrast image of each via. When a minority of the vias in the image have a significantly different brightness level than a majority of the vias, it is then determined that the minority of vias have defects.
