Abstract:
Lithography systems and methods are provided with enhanced performance based on broader utilization of the integrated metrology tool in the printing tool to handle the metrology measurements in the system in a more sophisticated and optimized way. Additional operation channels are disclosed, enabling the integrated metrology tool to monitor and/or allocate metrology measurements thereby and by a standalone metrology tool with respect to specified temporal limitations of the printing tool; to adjust and optimize the metrology measurement recipes; to provide better process control to optimize process parameters of the printing tool; as well as to group process parameters of the printing tool according to a metrology measurements landscape.
