摘要:
A source-collector module (SOCOMO) for generating a laser-produced plasma (LPP) that emits EUV radiation, and a grazing-incidence collector (GIC) mirror arranged relative to the LPP and having an input end and an output end. The LPP is formed using an LPP target system having a light source portion and a target portion, wherein a pulsed laser beam from the light source portion irradiates Sn vapor from a Sn vapor source of the target portion. The GIC mirror is arranged relative to the LPP to receive the EUV radiation at its input end and focus the received EUV radiation at an intermediate focus adjacent the output end. A radiation collection enhancement device may be used to increase the amount of EUV radiation provided to the intermediate focus. An EUV lithography system that utilizes the SOCOMO is also disclosed.
