Processed silicon wafers. Both of the wafers seen here contain over 200 identical microcircuits. The large grey squares on each wafer are test sites, used to ensure the accuracy of the manufacturing process at each stage. If the wafers pass all of their tests, they will be cut up so that each circuit may be fitted to a holder - creating the well-known microchip.
