Linear filament array sheet for EUV production

An EUV radiation source (12) that generates a sheet (36) of a liquid target material that has a width that matches the desired laser spot size (28) for good conversion efficiency and a thickness that matches the laser beam/target interaction depth. The EUV source (12) includes a reservoir (10) conta...

Beschreibung
Zusammenfassung:	An EUV radiation source (12) that generates a sheet (36) of a liquid target material that has a width that matches the desired laser spot size (28) for good conversion efficiency and a thickness that matches the laser beam/target interaction depth. The EUV source (12) includes a reservoir (10) containing a pressurized cryogenic liquid target material, such as liquid Xenon. The reservoir (10) also includes an array (14) of closely spaced orifices (16). The liquid target material is forced through the orifices (16) into a vacuum chamber as separated liquid stream filaments (20) of the target material that define the sheet (36). The liquid streams freeze to form an array of frozen target filaments (20). A laser beam (24) is directed to a target area (28) in the vacuum chamber where it irradiates the stream of filaments (20) to create a plasma (30) that emits EUV radiation (32).
