摘要:
System and method for implementing multi-resolution advanced process control (“APC”) are described. One embodiment is a method comprising obtaining low resolution metrology data and high resolution metrology data related to a process module for performing a process on the wafer; modeling a process variable of the process as a function of the low resolution metrology data to generate a low-resolution process model; and modeling the process variable as a function of the high resolution metrology data to generate a high-resolution process model. The method further includes calibrating the low resolution process model; combining the calibrated low resolution process model with the high resolution process model to generate a multi-resolution process model that models the process variable as a function of both the low resolution metrology data and the high resolution metrology data; and analyzing a response of the multi-resolution process model and the low and high resolution metrology data to control performance of a process module.
