    Abstract: A method and apparatus is provided for measuring multiple locations on a wafer for controlling a subsequent semiconductor processing step to achieve greater dimensional uniformity across that wafer. The method and apparatus maps a dimension of a feature at multiple locations to create a dimension map, transforms the dimension map into a processing parameter map, and uses the processing parameter map to tailor the subsequent processing step to that specific wafer. The wafer can also be measured after the processing to compare an actual outcome with the targeted outcome, and the difference can be used to refine the transformation from a dimension map to a processing parameter map for a subsequent wafer.

    Abstract: A wafer handling mechanism is operated to place a wafer on a chuck. A chucking force is then applied to the wafer, whereby wafer support features of the chuck transfer a defect pattern onto a surface of the wafer. The surface of the wafer is analyzed by a defect metrology tool to obtain a mapping of the defect pattern transferred onto the surface of the wafer. A center coordinate of the chuck within a coordinate system of the wafer is determined by analyzing the defect pattern as transferred to the surface of the wafer. A spatial offset between the center coordinate of the chuck and the center of the wafer is determined. The spatial offset is used to adjust the wafer handling mechanism so as to enable alignment of the center of the wafer to the center coordinate of the chuck.

    Abstract: A METHOD AND APPARATUS IS PROVIDED FOR MEASURING MULTIPLE LOCATIONS ON A WAFER (306) FOR CONTROLLING A SUBSEQUENT SEMICONDUCTOR-PROCESSING STEP TO ACHIEVE GREATER DIMENSIONAL UNIFORMITY ACROSS THAT WAFER. THE METHOD AND APPARATUS MAPS A DIMENSION OF A FEATURE AT MULTIPLE LOCATIONS TO CREATE A DIMENSION MAP (200), TRANSFORMS THE DIMENSION MAP INTO A PROCESSING PARAMETER MAP (502,504), AND USES THE PROCESSING PARAMETER MAP TO TAILOR THE SUBSEQUENT PROCESSING STEP TO THAT SPECIFIC WAFER. THE WAFER CAN ALSO BE MEASURED AFTER THE PROCESSING TO COMPARE AN ACTUAL OUTCOME WITH THE TARGETED OUTCOME, AND THE DIFFERENCE CAN BE USED TO REFINE THE TRANSFORMATION FROM A DIMENSION MAP TO A PROCESSING PARAMETER MAP FOR A SUBSEQUENT WAFER.(FIG 6)
