process. This is done to eliminate unsatisfactory wafer materials from the process stream and to sort the wafers into batches of uniform thickness and at a final inspection stage. These wafers will become the basic raw material for new integrated circuits. The following is a summary of the steps in a typical wafer manufacturing process.

The invention provides for an automated control flow to realize greater efficiency and assure process quality. In one aspect of the invention the wafer batch completing its operation is discharged simultaneous with the charging of the next batch. Essentially the operation takes place by overlapping processing operations.
