  • Publication number: 20120123734
    Abstract: Systems and methods for deciding whether or not to indicate misalignment. In some examples, an analysis of parametric data relating to tests sensitive to misalignment is performed in order to determine which data is incongruous and to identify corresponding probes or socket contacts as suspected misaligned. In some examples, additionally or alternatively, a spatial analysis quantifies the placement of a set of identified suspected misaligned probes, which were identified from pass/fail test data and/or parametric test data, with respect to a contiguous or non-contiguous area on one or more wafers.

  • Publication number: 20120109874
    Abstract: Methods and systems for semiconductor testing. In one embodiment, a semiconductor testing method includes one or more of the following stages: defining a rule relating to semiconductor testing, validating the rule, bundling the rule with other rules, correlating the rule with other rules, publishing the rule, actualizing the rule, and follow up relating to the rule. In one embodiment, a semiconductor testing system includes one or more of the following modules: rule creation module(s), analysis module(s), simulation module(s), real time production module(s), and offline production module(s). In one embodiment, user friendly graphical user interface(s) can be used for defining the building blocks of a rule and/or for viewing an optional hierarchy of categories to which the rule belongs.

  • Patent number: 8112249
    Abstract: A parametric test time reduction method for reducing time expended to conduct a test program flow on a population of semiconductor devices, the test program flow comprising at least one parametric test having a specification defining a known pass value range characterized in that a result of the test is considered a passing result if the result falls within the known pass value range, the method including: computing an estimated maximum test range, at a given confidence level, on a validation set including a subset of the population of semiconductor devices, the estimated maximum test range including the range of values into which all results from performing the test on the set will statistically fall at the given confidence level and at least partly disabling the at least one parametric test based at least partly on a comparison of the estimated maximum test range and the known pass value range.

  • Publication number: 20110000829
    Abstract: Systems and methods for sorting an electronic device undergoing a final test operation in accordance with a test program, into one of a plurality of bins. In one embodiment, an evaluator defines the binning of the electronic device while the device is still socketed, and the defined binning may or may not concur with the binning assigned by the test program.

  • Patent number: 7777515
    Abstract: Methods and systems of semiconductor testing where reference dice and non-reference dice in a wafer and/or lot are tested differently. In one embodiment of the invention, geography, lithography exposure, other characteristics, performance and/or behavior are taken into account when selecting reference dice, thereby improving the likelihood that the response of reference dice to testing is well representative of the wafer and/or lot. In one embodiment, based on data from the testing of reference dice, the test flow for non-reference dice and/or other testing may or may not be adjusted.
