Patent ID: 7536230

Claim:
A control method for controlling a physical state of a processing device for processing a target object so that the target object reaches a desired physical state, wherein the processing device is comprised of a plurality of channels each configured to apply a physical parameter to the target object at a location, and a measure point is located at each of the locations which is configured to measure a physical state of the target object at the location, comprising the steps of: finding electronically sets of relation information showing a relation between a physical parameter applied through one or more channels of the processing device and an actual physical state of the target object through the measure points, wherein the sets of relation information is based on a physical state change of the target object at the measure points when physical parameters are applied through the channels of the processing device; finding electronically physical state distribution information of the target object based on measured physical states of the target object at the measure points before application of physical parameters through the channels of the processing device; storing electronically the sets of relation information into at least one interference matrix; and finding electronically sets of adjustment information based on the sets of relation information stored in the at least one interference matrix and the physical state distribution information of the target object; and applying physical parameters through the channels of the processing device so that the target object reaches the desired physical state based on the adjustment information.
