  • Ambient temperature ball bond
    Patent number: 8767351
    Abstract: The presently disclosed technology describes systems and methods for attaining a ball bond using less than 1 thousandth of an inch diameter gold wire using ultrasonic bonding energy and without heating an underlying bonding pad. The ball bond allows the use of particularly small bonding pads that are particularly close to adjacent microelectronic structures that limit the use of other bonding techniques that have shallow take-off angles.

  • INHIBITORS OF HCV NS5A PROTEIN
    Publication number: 20130310427
    Abstract: Antiviral compounds may be used to inhibit or reduce the activity of Hepatitis C virus (HCV), particularly HCV's NS5A protein. In these contexts, inhibition and reduction of activity of the NS5A protein refers to a lower level of the measured activity relative to a control experiment in which the cells or the subjects are not treated with the test compound. The inhibition or reduction in the measured activity is at least a 10% reduction or inhibition. The compounds and their isomeric forms and pharmaceutically acceptable salts thereof are useful in treating and preventing HCV infection alone or when used in combination with other compounds targeting viral or cellular elements or functions involved in the HCV lifecycle.
