A factory, an apparatus, and methods of using an in situ finishing information for finishing workpieces and semiconductor wafers are described. Changes or improvements to cost of manufacture of a workpiece using in-process cost of manufacture information, tracked in-process cost of manufacture information, or cost of manufacture parameters are discussed. Appreciable changes to quality or cost of manufacture of a workpiece using tracking, using in-process tracked information, networks including a multiplicity of apparatus, and using in situ finishing information are discussed. A factory, apparatus, and methods to change or improve process control are discussed. A factory, apparatus, and methods to change or improve real-time process control are discussed. A factory, apparatus, and methods to change or improve predictive control are discussed. The workpieces can be tracked individually or by process group such as a process batch.
