Zusammenfassung: | Disclosed herein is a method for determining one or more control parameters of a manufacturing process comprising a lithographic process and one or more further processes, the method comprising: obtaining an image of at least part of a substrate, wherein the image comprises at least one feature manufactured on the substrate by the manufacturing process; calculating one or more image-related metrics in dependence on a contour determined from the image, wherein one of the image-related metrics is an edge placement error, EPE, of the at least one feature; and determining one or more control parameters of the lithographic process and/or said one or more further processes in dependence on the edge placement error, wherein at least one control parameter is determined so as to minimize the edge placement error of the at least one feature. |
