    摘要: A method for determining the root causes of fail patterns in integrated circuit chips is provide wherein a known integrated circuit chip layout is used to identify a plurality of potential defects and a plurality of potential fail patterns in the integrated circuit chip. Correlations between the potential defects and the potential fail patterns that result from those defects are identified. Based on this identification, the potential fail patterns are grouped by common potential defect. An actual integrated circuit chip that is manufactured in accordance with the test layout is tested for failure patterns. These failure patterns are then compared to the groupings of potential fail patterns. When a match is found, that is when a given group of fail patterns is found in the actual integrated circuit chip, then the potential defect associated with the potential fail patterns to which the actual fail patterns are matched is identified. This defect is the root cause of the failure pattern in the actual chip.

    摘要: An on-chip technique for noncontact electrical testing of a test structure on a chip is provided. On-chip photodiodes receives pump light from a pump light source, where the on-chip photodiodes are electrically connected to the test structure and are configured to generate power for the test structure. An on-chip coupling unit receives probe light from a probe light source, where the on-chip coupling unit is optically connected to on-chip waveguides through which the probe light is transferred. On-chip switches open in response to receiving voltage output from the test structure, and the on-chip switches remain closed when the voltage output is not received from the test structure. The on-chip switches pass the probe light when opened by the voltage output from the test structure. The on-chip switches block the probe light by remaining closed, when the voltage output is not received from the test structure.

    摘要: A modularized capacitor array includes a plurality of capacitor modules. Each capacitor module includes a capacitor and a switching device that is configured to electrically disconnect the capacitor. The switching device includes a sensing unit configured to detect the level of leakage of the capacitor so that the switching device disconnects the capacitor electrically if the leakage current exceeds a predetermined level. Each capacitor module can include a single capacitor plate, two capacitor plates, or more than two capacitor plates. The leakage sensors and switching devices are employed to electrically disconnect any capacitor module of the capacitor array that becomes leaky, thereby protecting the capacitor array from excessive electrical leakage.

    摘要: A method for identifying potentially defective integrated circuit chips and excluding them from future testing as wafers move through a manufacturing line The method includes data-collecting steps, tagging the chips on wafers identified as potentially bad chips based on information collected as the wafer moves down the fabrication line, evaluating test cost savings by eliminating any further tests on the tagged chips preferably using a test cost database. Considering all the future tests to be preformed, the tagged chips are skipped if it is determined that the test cost saving is significant. Tagging bad chips is based on various criteria and models which are dynamically adjusted by performing the wafer final test on samples of the tagged chips and feeding-back the final test results. The dynamic adaptive adjustment method preferably includes a feedback loop or iterative process to evaluate financial tradeoffs when assessing the profit of salvaging chips against the additional test costs.
