    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.

    摘要: In accordance with an embodiment, a method for exception handling comprises accessing an exception type for an exception, filtering historical data based on at least one defined criterion to provide a data train comprising data sets, assigning a weight to each data set, and providing a current control parameter. The data sets each comprise a historical condition and a historical control parameter, and the weight assigned to each data set is based on each historical condition. The current control parameter is provided using the weight and the historical control parameter for each data set.

    摘要: The present disclosure provides a method. The method includes gathering advanced process control (APC) data from a subset of available wafers and a subset of available processing chambers. The method includes establishing a matrix that contains a plurality of cells. The cells each correspond to one of the available wafers and one of the available processing chambers. The matrix is partially filled by populating cells for which the APC data has been gathered. The method includes determining a plurality of chamber-coverage-rate (CCR) parameters associated with the matrix. The method includes optimizing the CCR parameters through an iteration process to obtain optimized CCR parameters. The method includes predicting an APC data value for a designated cell of the matrix based on the optimized CCR parameters. The designated cell is an empty cell before the predicting and is populated by the predicting.
