  • Patent number: 8997242
    Abstract: Systems and techniques for managing software licensing are described. When a computing system service request is made, the request is intercepted and software information that may be more or less continuously updated in a managed computing environment is examined to determine the effect of the service request on software usage by the system. The software usage represented by the service request is evaluated based on licensing information to determine license usage by the system and changes in license usage based on the service request, and license usage information is determined based on the software usage and the licensing information. The license usage information may be used in connection with a system of rules to govern actions such as reporting licensing usage or allowing or preventing the use of software based on whether use of the software will violate licensing requirements.

  • Patent number: 8993218
    Abstract: One or more techniques or systems for controlling a profile for photo resist (PR) are provided herein. In some embodiments, a first shield layer is formed on a first PR layer and a second PR layer is formed on the first shield layer. A first window is formed within the second PR layer during a first exposure with a mask. A second window is formed within the first shield layer based on the first window. A third window is formed within the first PR layer during a second exposure without a mask. Because, the third window is formed while the first shield layer and the second PR layer are on the first PR layer, a profile associated with the first PR layer is controlled. Contamination during ion bombardment is mitigated due to the controlled profile.
