DOF Enhanced via the Multi-Wavelength Method for the Moiré Fringe-Based Alignment
Alignment systems are core subsystems of lithography, which directly affect the overlay accuracy of the lithography process. The Moiré fringe-based alignment method has the advantages of high precision and low complexity. However, the precision of this method is highly sensitive to variations in the...
