    Abstract: A lithographic apparatus comprising a support structure constructed to support a patterning device, the patterning device being capable of imparting an EUV radiation beam with a grating in its cross-section to form a patterned EUV radiation beam, and a projection system configured to project the patterned EUV radiation beam onto a target portion of the substrate, wherein the support structure is provided with a grating comprising a series of first reflective portions which alternates with a series of second reflective portions, the second reflective portions having a reflectivity which is less than the reflectivity of at least part of the first reflective portions and which is greater than zero.

    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 should 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, the reference substrate parameter and the substrate parameter. The fingerprint may then be used to control the lithographic process.
