  • Semiconductor yield management system and method
    Patent number: 6470229
    Abstract: A system and method for yield management is disclosed wherein a data set containing one or more prediction variable values and one or more response values is input into the system. The system can pre-process the input data set to remove prediction variables with missing values and data sets with missing values. The pre-processed data can then be used to generate a model that may be a decision tree. The system can accept user input to modify the generated model. Once the model is complete, one or more statistical analysis tools can be used to analyze the data and generate a list of the key yield factors for the particular data set.
    Type: Grant

    Date of Patent: October 22, 2002
    Assignee: Yield Dynamics, Inc.
