Abstract:
A method is described for measuring a moving property of a target. The method includes: forming a remaining plasma that at least partially coincides with an extended target region, the remaining plasma being a plasma formed from an interaction between a prior target and a prior radiation pulse in a target space; releasing a current target along a trajectory toward the target space that is at least partly overlapping the extended target region; determining one or more moving properties of the current target when the current target is within the extended target region and after a prior and adjacent target has interacted with a prior radiation pulse in the target space; and if any of the determined one or more moving properties of the current target are outside an acceptable range, then adjusting one or more characteristics of a radiation pulse directed toward the target space.

Claim (Index 15):
An apparatus comprising:\n a chamber that defines a target space, a first region, and a second region closer to the target space than the first region; a target delivery system configured to release a plurality of targets each along a trajectory toward the target space, wherein each target includes a component that emits extreme ultraviolet (EUV) light when converted to plasma; a diagnostic system that diagnostically interacts with a current target when the current target is within the second region and after a prior and adjacent target has interacted with a prior radiation pulse in the target space, wherein the diagnostic system comprises:\n a single light source configured to produce a light beam; and \n one or more optical components configured to split the light beam into two diagnostic light beams and direct the diagnostic light beams in parallel directions toward the trajectory to thereby intersect with and interact with the current target at distinct locations and times such that the beam waists of the diagnostic light beams overlap the trajectory; and \n a control system that is in communication with the optical source and the diagnostic system, and is configured to determine one or more moving properties of the current target based on data outputted from the diagnostic system.
