    摘要: A method includes providing a plurality of failure dies, and performing a chip probing on the plurality of failure dies to generate a data log comprising electrical characteristics of the plurality of failure dies. An automatic net tracing is performed to trace failure candidate nodes in the failure dies. A failure layer analysis is performed on results obtained from the automatic net tracing. Physical failure analysis (PFA) samples are selected from the plurality of failure dies using results obtained in the step of performing the failure layer analysis.

    摘要: A method comprises computing respective regression models for each of a plurality of failure bins based on a plurality of failures identified during wafer electrical tests. Each regression model outputs a wafer yield measure as a function of a plurality of device performance variables. For each failure bin, sensitivity of the wafer yield measure to each of the plurality of device performance variables is determined, and the device performance variables are ranked with respect to sensitivity of the wafer yield measure. A subset of the device performance variables which have highest rankings and which have less than a threshold correlation with each other are selected. The wafer yield measures for each failure bin corresponding to one of the selected subset of device performance variables are combined, to provide a combined wafer yield measure. At least one new process parameter value is selected to effect a change in the one device performance variable, based on the combined wafer yield measure. The at least one new process parameter value is to be used to process at least one additional wafer.

    摘要: A system and method of automatically calculating boundaries for a semiconductor fabrication process. The method includes selecting a first parameter for monitoring during a semiconductor fabrication process. A first set of values for the first parameter are received and a group value of the first set is determined. Each value in the first set of values is normalized. A first weighting factor is selected based on a number of values in the first set. The embodiment also includes generating a first and a second boundary value as a function of the weighting factor, the first set normalized values and the group value of the first set and applying the first and second boundary values to control the semiconductor fabrication process.
