  • Patent number: 11054459
    Abstract: A per-chip equivalent oxide thickness (EOT) circuit sensor resides in an integrated circuit. The per-chip EOT circuit sensor determines electrical characteristics of the integrated circuit. The measured electrical characteristics include leakage current. The determined electrical characteristics are used to determine physical attributes of the integrated circuit.

  • Patent number: 8765568
    Abstract: A structure and method of fabricating the structure includes a semiconductor substrate having a top surface defining a horizontal direction and a plurality of interconnect levels stacked from a lowermost level proximate the top surface of the semiconductor substrate to an uppermost level furthest from the top surface. Each of the interconnect levels include vertical metal conductors physically connected to one another in a vertical direction perpendicular to the horizontal direction. The vertical conductors in the lowermost level being physically connected to the top surface of the substrate, and the vertical conductors forming a heat sink connected to the semiconductor substrate. A resistor is included in a layer immediately above the uppermost level. The vertical conductors being aligned under a downward vertical resistor footprint of the resistor, and each interconnect level further include horizontal metal conductors positioned in the horizontal direction and being connected to the vertical conductors.

  • Publication number: 20120259575
    Abstract: Disclosed is an integrated circuit chip incorporating a test circuit having multiple logic blocks. Each logic block is a matrix of individually selectable, physically different, test devices in a specific class of devices. An embedded processor ensures that specific stress conditions are selectively applied to the test devices and further controls selective testing, by a sensor system, of the test devices to determine the impact of the applied stress conditions. In a laboratory or test system environment, accelerated stress conditions are selectively applied to the test devices and the testing results are used to model device performance degradation due to class-specific failure mechanisms. In the field, stress conditions are selectively applied to test devices so as to mimic stress conditions impacting active devices in use on the same chip and the testing results are used to indirectly monitor performance degradation of the active devices due to class-specific failure mechanisms.

  • Patent number: 8217671
    Abstract: A parallel array architecture for constant current electro-migration stress testing is provided. The parallel array architecture comprises a device under test (DUT) array having a plurality of DUTs coupled in parallel and a plurality of localized heating elements associated with respective ones of the DUTs in the DUT array. The architecture further comprises DUT selection logic that isolates individual DUTs within the array. Moreover, the architecture comprises current source logic that provides a reference current and controls the current through the DUTs in the DUT array such that each DUT in the DUT array has substantially a same current density, and current source enable logic for selectively enabling portions for the current source logic. Electro-migration stress testing is performed on the DUTs of the DUT array using the heating elements, the DUT selection logic, current source logic, and current source enable logic.
