    • PROBLEM TO BE SOLVED: To provide a radiation source device in which individual provision of gas in an area where radiation travels from a radiation source to an illuminator is extremely small with regard to the suppression of debris particles in the area.
      SOLUTION: The lithographic apparatus includes the radiation source for generating the radiation, an illuminating system for adjusting the radiation, a patterning device for patterning the adjusted radiation, and a projection system for projecting the patterned radiation onto a target section of a substrate. The illuminating system includes a debris suppressing system for suppressing the debris particles produced by the generation of the radiation and an optical system for collecting the radiation. The debris suppressing systems are disposed so as to directly evaporate the debris particles, to directly charge the debris particles, to directly generate plasma from the debris particles, or to perform those arbitrary combinations, in a path where the radiation travels from radiation source to the optical system.

    • 要解决的问题:提供一种辐射源装置,其中在辐射源从辐射源传播到照明器的区域中单独提供气体对于抑制该区域中的碎屑颗粒是非常小的。 解决方案:光刻设备包括用于产生辐射的辐射源,用于调节辐射的照明系统,用于对经调节的辐射进行图案化的图案形成装置,以及用于将图案化辐射投影到基板的目标部分上的投影系统 。 照明系统包括用于抑制由辐射产生产生的碎屑颗粒的碎片抑制系统和用于收集辐射的光学系统。 碎片抑制系统被设置成直接蒸发碎屑颗粒,直接对碎屑颗粒进行充填,从碎片颗粒直接产生等离子体,或者在辐射从辐射源传播到 光学系统。 版权所有(C)2009,JPO&INPIT
