Since 2002, we have been developing a CO₂-Sn-LPP EUV light source, the most promising solution as the 13.5 nm high power (>200 W) light source for HVM EUV lithography. Because of its high efficiency, power scalability and spatial freedom around plasma. Our group has proposed several unique original technologies; 1) CO₂ laser driven Sn plasma generation, 2) Double laser pulse shooting for higher Sn ionization rate and higher CE. 3) Sn debris mitigation with a magnetic field, 4) Hybrid CO₂ laser system that is scalable with a combination of a short pulse oscillator and commercial cw-CO₂ amplifiers. 5) High efficient out of band light reduction with grating structured C1 mirror. In past paper we demonstrated in small size (2Hz) experimental device, this experiment shoed the advantage of combining a laser beam at a wavelength of the CO₂ laser system with Sn plasma to achieve high CE>4.7% (in maximum) from driver laser pulse energy to EUV in-band energy ¹). In this paper we report the further updated results from last paper. (1) 20um droplets at 100kHz operation was successfully ejected by downsized nozzle and demonstrated dramatical improvement of debris on the collector mirror. We have been developing extension of high CE operation condition at 20kHz range, We have reported component technology progress of EUV light source system. (2)New generation collector mirror with IR reduction technology is equipped in mirror maker. (3)20kW CO₂ laser amplifier system is demonstrated cooperate with Mitsubishi electric. (4) We develop new Proto #2 EUV LPP source system and demonstrated 200W EUV plasma power (43W EUV clean power at I/F ) at 100kHz operation was confirmed. (5) High conversion efficiency (CE) of 3.9% at 20kHz operation was confirmed in using pico-second pre-pulse laser. (6)Improvement of CO₂ laser power from 8kW to 12kW is now on going by installation of new pre-amplifier. (7)Power-up scenario of HVM source is reported, target shipment of first customer beta LPP light source unit is 2015.

There has been a significant progress in the X-ray generation technologies for various laboratory and production application by laser-Compton scheme and laser produced plasma. Femtosecond X-ray generation was performed by Compton scattering through interaction between a 3-ps electron beam and 100-fs laser photons in a 90 degree scattering configuration. The X-ray energy and pulse duration were estimated as 2.3keV and 280fs from the observed electron and laser beam parameters. The fluctuation of the X-ray output was measured as 25% rms during a 30-min operation, and analyzed as a function of fluctuations of parameters like timing between the electron and laser beam, electron beam charge, laser beam energy, pulse widths, and spatial stability. Further reduction of the fluctuation is possible by improvement of timing stability down to 100fs region. All optical synchronization scheme was proposed and component technologies are under development. The novel scheme employs optical control of linear accelerator and femtosecond lasers by optical locking of lasing between different laser oscillators. Two mode-locked Ti:sapphire lasers of different wavelengths were precisely synchronized by a simple feedback system employing sum frequency generation. The measured rms timing jitter between two lasers was 28fs. Clean EUV light source is strongly demanded for next generation lithography, with 13.5nm, 2%bw, 100W and high pulse stability of less than 1%. The most promising approach is to employ a liquid Xe jet of 10-30 micron-meter diameter as the plasma source with high repetition rate solid state laser. The laser pulse energy usually fluctuates more than a few % and liquid jet fluctuates of the position up to 10% of the diameter. Higher repetition rate plasma generation causes acoustic instability inside the liquid jet. All these obstacles prevent to achieve the desired EUV stability. Discussion will be given on these issues and new architecture is proposed to achieve a clean and stable EUV light source.
