    Abstract: A lithographic process is one that applies a desired pattern onto a substrate, usually onto a target portion of the substrate. During the lithographic process, the focus needs to be controlled. There is disclosed a method for determining a fingerprint of a performance parameter associated with a substrate, such as a focus value to be used during the lithographic process. A reference fingerprint of the performance parameter is determined for a reference substrate. A reference substrate parameter of the reference substrate is determined. A substrate parameter for a substrate, such as a substrate with product structures, is determined. Subsequently, the fingerprint of the performance parameter is determined based on the reference fingerprint, reference substrate parameter and the substrate parameter. The fingerprint may then be used to control the lithographic process.

    Abstract: A measurement mark is disclosed. According to certain embodiments, the measurement mark includes a set of first test structures developed in a first layer on a substrate, each of the set of first test structures comprising a plurality of first features made of first conducting material. The measurement mark also includes a set of second test structures developed in a second layer adjacent to the first layer, each of the set of second test structures comprising a plurality of second features made of second conducting material. The measurement mark is configured to indicate connectivity between the set of first test structures and associated second test structures in the set of second test structures when imaged using a voltage-contrast imaging method.

    Abstract: Apparatus and methods for determining a focus error for a lithographic apparatus and/or a difference between first and second metrology data. The first and/or second metrology data comprising a plurality of values of a parameter relating to a substrate, the substrate including a plurality of fields comprising device topology., Apparatus may comprise a processor configured to execute computer program code to undertake the method of: determining an intra-field component of the parameter; removing the determined intra-field component from the first metrology data to obtain an inter-field component of the first metrology data; and determining the difference between the first metrology data and second metrology data based on the inter-field component and the second metrology data.
