Abstract:
Metrology methods and modules are provided, which comprise carrying out recipe setup procedure(s) and/or metrology measurement(s) using zonal analysis with respect to respective setup parameter(s) and/or metrology metric(s). The zonal analysis comprises relating to spatially variable values of the setup parameter(s) and/or metrology metric(s) across one or more wafers in one or more lots. Wafer zones may be discrete or spatially continuous, and be used to weight one or more parameter(s) and/or metric(s) during any of the stages of the respective setup and measurement processes.
