  • Patent number: 9336109
    Abstract: A method of testing a device is disclosed. Test data is obtained for a device testing program that tests the device. An adaptation command for testing the device is determined at an adaptive testing engine using obtained test data. The adaptation command is sent from the adaptive testing engine to a tool control application. The tool control application uses the adaptation command to control an operation related to the testing of the device.

  • Patent number: 8689066
    Abstract: A method of implementing integrated circuit device testing includes performing baseline testing of a first group of chips using a full set of test patterns, and for chip identified as failing, determining, a score for each test pattern in the full set. The score is indicative of an ability of the test pattern to uniquely identify a failing chip with respect to other test patterns. Following the baseline testing, streamlined testing on a second group of chips is performed, using a reduced set of the test patterns having highest average scores as determined by the baseline testing. Following the streamlined testing, full testing on a third group of chips is performed using the full set of test patterns, and updating the average score for each pattern. Further testing alternates between the streamlined testing and the full testing for additional groups of chips.

  • Patent number: 8087823
    Abstract: A structure has a heat dissipating feature, an internal temperature measurement device, and a memory. The structure generates heat as power is supplied to the structure, and a threshold voltage of the internal temperature measurement device changes as the temperature of the temperature measurement device changes. The embodiments herein establish a linear relationship between temperature and threshold voltage by heating the structure to a first temperature and recording a first threshold voltage, and then heating the structure to a second temperature and recording a second threshold voltage. From this, the embodiments herein calculate a linear relationship between temperature and threshold voltage. Further, the embodiments herein can calculate the temperatures of the structure based only upon the linear relationship and threshold voltages measured from internal temperature measurement device.

  • Patent number: 7620931
    Abstract: An integrated circuit, a method and a system for designing and a method fabricating the integrated circuit. The method including: (a) generating a photomask level design of an integrated circuit design of the integrated circuit, the photomask level design comprising a multiplicity of integrated circuit element shapes; (b) designating regions of the photomask level design between adjacent integrated circuit element shapes, the designated regions large enough to require placement of fill shapes between the adjacent integrated circuit elements based on fill shape rules, the fill shapes not required for the operation of the integrated circuit; and (c) placing one or more monitor structure shapes of a monitor structure in at least one of the designated regions, the monitor structure not required for the operation of the integrated circuit.

  • Patent number: 7194706
    Abstract: A method is disclosed for designing scan chains in an integrated circuit chip with specific parameter sensitivities to identify fabrication process defects causing test fails and chip yield loss. The composition of scan paths in the integrated circuit chip is biased to allow them to also function as on-product process monitors. The method adds grouping constraints that bias scan chains to have common latch cell usage where possible, and also biases cell routing to constrain scan chain routing to given restricted metal layers for interconnects. The method assembles a list of latch design parameters which are sensitive to process variation or integrity, and formulates a plan for scan chain design which determines the number and the length of scan chains. A model is formulated of scan chain design based upon current state of yield and process integrity, wherein certain latch designs having dominant sensitivities are chosen for specific ones of the scan chains on the chip.

  • Patent number: 6789032
    Abstract: A statistical method is described for reliability selection of dies on semiconductor wafers using critical wafer yield parameters. This is combined with other data from the wafer or module level reliability screens (such as voltage screen or burn-in) to obtain the relative latent defect density. Finally the modeled results are compared with actual results to demonstrate confidence in the model.
