Zusammenfassung:An inspection substrate for inspecting a component, such as a liquid confinement system, of an apparatus for processing production substrates is discussed. The inspection substrate includes a body having dimensions similar to a production substrate so that the inspection substrate is compatible with the apparatus, an illumination device, such as light emitting diodes, embedded in the body, a sensor, such as an imaging device or a pressure sensor, that is embedded in the body and configured to generate inspection information, such as image data, relating to a parameter of the component of the apparatus proximate to the inspection substrate, and a storage device embedded in the body and configured to store the inspection information.
