DEVICE CONSTRUCTED AND ARRANGED TO GENERATE RADIATION, LITHOGRAPHIC APPARATUS, AND DEVICE MANUFACTURING METHOD

摘要

A device is constructed and arranged to generate radiation by using an electrical discharge through a gaseous medium. The device includes a first electrode and a second electrode, and a liquid supply arranged to provide a liquid to a location in the device. The device is arranged to be electrically supplied with a voltage and to supply the voltage at least partially to the first electrode and the second electrode in order to allow the electrical discharge to be generated in an electrical field created by the voltage. The electrical discharge produces a radiating plasma. The device also includes a shield arranged between the discharge location and a conducting part connected to the first electrode and/or the second electrode.
