Abstract:
Process control methods, metrology targets and production systems are provided for reducing or eliminating process overlay errors. Metrology targets have pair(s) of periodic structures with different segmentations, e.g., no segmentation in one periodic structure and device-like segmentation in the other periodic structure of the pair. Process control methods derive metrology measurements from the periodic structures at the previous layer directly following the production thereof, and prior to production of the periodic structures at the current layer, and use the derived measurements to adjust lithography stage(s) that is part of production of the current layer. Production system integrate lithography tool(s) and metrology tool(s) into a production feedback loop that enables layer-by-layer process adjustments.

Claim (Index 13):
