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.

Abstract: Methods, systems, computer-program products and program-storage devices for determining whether or not to perform an action based at least partly on an estimated maximum test-range. One method comprises: attaining results generated from a parametric test on semiconductor devices included in a control set; selecting from the semiconductor devices at least one extreme subset including at least one of a high-scoring subset and a low-scoring subset; plotting at least results of the at least one extreme subset; fitting a plurality of curves to a plurality of subsets of the results; extending the curves to the zero-probability axis for the low-scoring subset or the one-probability axis for the high-scoring subset to define a corresponding plurality of intersection points; defining an estimated maximum test range based on at least one of the intersection points; and determining whether or not to perform an action based at least partly on the estimated maximum test range.

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.
