摘要： An extreme ultraviolet light system includes a drive laser system, an extreme ultraviolet light chamber including an extreme ultraviolet light collector and a target material dispenser including a target material outlet capable of outputting a plurality of portions of target material along a target material path, wherein the target material outlet is adjustable. The extreme ultraviolet light system further includes a drive laser steering device, a detection system including at least one detector directed to detect a reflection of the drive laser reflected from the first one of the plurality of portions of target material and a controller coupled to the target material dispenser, the detector system and the drive laser steering device. The controller includes logic for detecting a location of a first one of the plurality of portions of target material from a first light reflected from the first target material.

摘要： An apparatus includes a drive laser system producing an amplified light beam of pulses that travels along a drive axis; a beam delivery system that directs the amplified light beam of pulses toward a target region; a target material delivery system that provides a target mixture containing a target material in the target region; two or more sensors radially separated from a main axis that crosses the target region, the two or more sensors being configured to detect energy of ultraviolet electromagnetic radiation emitted from a plasma state of the target material when the amplified light beam of pulses intersects the target mixture; and a controller that receives the output from the two or more sensors. The controller is configured to estimate a relative radial alignment between the target mixture and the drive axis within the target region based on an analysis of the detected energy.
