  • Integrated circuit bond pad structures and methods of making
    Patent number: 7232705
    Abstract: A bond pad structure for an integrated circuit includes first and second active devices formed in a substrate, first and second buses above the first and second active devices, respectively, a bond pad above the first and second buses, first interconnections between the first and second active devices and the bond pad, and second interconnections between the first and second active devices and the first and second buses, respectively. The first active device may be at least one PMOS transistor, and the second active device may be at least one NMOS transistor. A guard band region may be formed in the substrate.
    Type: Grant

  • Magnetic snapback sensor circuit and electrostatic discharge circuit using same
    Patent number: 6650103
    Abstract: A magnetic snapback sensor circuit for sensing current transients imposed on the snapback circuit including a current conductor loop; a conductor carrying current from a snapback circuit subject to current transients and intersecting with the conductor loop for magnetically generating a current in the loop; and a current detector circuit for generating an output responsive to the current flowing in the loop induced by a current transient.

  • Elevated voltage level I.sub.DDQ failure testing of integrated circuits
    Patent number: 5519333
    Abstract: Burn in testing of static CMOS IC's is eliminated by I.sub.DDQ testing at elevated voltage levels. These voltage levels are at least 25% higher than the normal operating voltage for the IC but are below voltage levels that would cause damage to the chip.
