因此,加速器系统复杂性、造价昂贵等缺点变得可以接受起来,以全相干的 FEL (Free Electron Laser)装置为例,FEL因子通常可做到0.1%,也就是说,要得到10kW的EUV(92eV,对应13.5nm波长),束流功率做到10MW即可。 当然10MW的束流功率也是非常大的,这里可以对比下,上海硬X射线自由电子激光装置(SHINE)的束流功率约0.8MW,上海软X射线自由电子激光装置(SXFEL)的束流功率可以忽略不计。 上海同步辐射光源(SSRF)的束流功率 …
High-power EUV free-electron laser for future lithography
2023年4月19日 · The EUV-FEL light source can generate high EUV power of more than 10 kW without tin debris and, as a result, it can provide more than 1 kW EUV power for 10 scanners at the same time without tin contamination to Mo/Si mirrors. Furthermore, the EUV-FEL is upgradable to a BEUV-FEL for finer pattering with a shorter wavelength (6.6–6.7 nm).
