High temperature EUV source nozzle

A nozzle (46) for a laser-plasma EUV radiation source that provides thermal isolation between the nozzle body (48) and the target material flowing therethrough. A target delivery tube (72) is provided that extends through the nozzle body (48). The delivery tube (72) has an expansion aperture (80) po...

Zusammenfassung:	A nozzle (46) for a laser-plasma EUV radiation source that provides thermal isolation between the nozzle body (48) and the target material flowing therethrough. A target delivery tube (72) is provided that extends through the nozzle body (48). The delivery tube (72) has an expansion aperture (80) positioned behind an exit collimator (50) of the nozzle body (48). The delivery tube (72) is made of a low thermal conductivity material, such as stainless steel, and is in limited contact with the nozzle body (48) so that heating of the nozzle body (48) from the plasma does not heat the liquid target material being delivered through the delivery tube (72). The expansion aperture (80) has a smaller diameter than the exit collimator (50).
