    摘要: A method and system for determining minimum post production test time on an integrated circuit device to achieve optimal reliability of that device utilizing defect counts. The number of defective cells or active elements with defective cells (DEFECTS) on the integrated circuit device are counted and this count serves as a basis for determining the minimum test time. A higher number of DEFECTS results in longer post production testing in order to achieve optimum reliability of the integrated circuit device. The number of DEFECTS can be counted on a device internal to the integrated circuit device and made available to determine the minimum required test time. The number of DEFECTS can also be obtained external to the integrated circuit device by intercepting information routed to another device. Information provided internally and externally can also reveal the physical location of DEFECTS to further refine the minimum required test time.

    摘要: A method of modeling yield for semiconductor products includes determining expected faults for each of a plurality of library elements by running a critical area analysis on each of the library elements, and assessing, from the critical area analysis, an expected number of faults per unit area, and comparing the same to actual observed faults on previously manufactured semiconductor products. Thereafter, the expected number of faults for each library element is updated in response to observed yield. A database is established, which includes the die size and expected faults for each of the library elements. Integrated circuit product die size is estimated, and library elements to be used to create the integrated circuit die are selected. Fault and size data for each of the selected library elements are obtained, the adjusted estimated faults for each of the library elements are summed, and estimated yield is calculated.

    摘要: 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.
