【摘要】:光刻機(jī)工件臺是光刻機(jī)的關(guān)鍵子系統(tǒng),其中的線管組件是其傳輸信號、動力及冷卻液等必不可少的組成部分。線管組件產(chǎn)生的擾動力會惡化工件臺系統(tǒng)的超精密運動性能,因此抑制線管組件擾動力對提高工件臺系統(tǒng)的運動性能具有重要意義。該文以工件臺系統(tǒng)的子系統(tǒng)掩模臺系統(tǒng)的線管組件為例,以減小線管組件擾動力波動、提高掩模臺運動性能為目的,建立了線管組件有限元模型,對線管組件的主要結(jié)構(gòu)參數(shù)進(jìn)行了優(yōu)化,提出了線管組件優(yōu)化的一些準(zhǔn)則,并進(jìn)行了實驗驗證。實驗表明:該有限元模型與實驗相比的一階頻率誤差在10%以內(nèi),驗證了模型的準(zhǔn)確性。仿真實驗結(jié)果表明:優(yōu)化后的線管組件L向擾動力波動幅值減小80%。
[Abstract]:The workpiece table of lithography machine is the key subsystem of lithography machine, in which the line tube component is its transmission signal. The disturbing force generated by the wire tube assembly will worsen the ultra-precision motion performance of the workpiece system. Therefore, it is very important to restrain the disturbance force of the wireline tube assembly to improve the motion performance of the workpiece platform system. In this paper, the wireline tube component of the subsystem mask platform system of the workpiece platform system is taken as an example to reduce the disturbing dynamic fluctuation of the wire tube assembly. For the purpose of improving the motion performance of the mask platform, the finite element model of the wire tube assembly is established, the main structural parameters of the line tube assembly are optimized, and some criteria for the optimization of the line tube assembly are put forward. The experimental results show that the first-order frequency error of the finite element model is less than 10%. The simulation results show that the amplitude of L-direction disturbance dynamic fluctuation of the optimized tube assembly is reduced by 80%.
