Abstract
The present invention provides for a method and an apparatus for performing automated rework in a manufacturing process. A lot of semiconductor devices is processed using a first set of control input parameters. The first set of control input parameters is stored in a memory location. Process data from the processing of the lot of semiconductor devices is acquired. Errors in the process data are analyzed. At least one automated rework procedure is performed on the lot of semiconductor devices in response to the analysis of the process data.
