    Abstract: Systems and methods are disclosed for protecting an EUV light source plasma production chamber optical element surface from debris generated by plasma formation. In one aspect of an embodiment of the present invention, a shield is disclosed which comprises at least one hollow tube positioned between the optical element and a plasma formation site. The tube is oriented to capture debris while allowing light to pass through the tube's lumen via reflection at relatively small angles of grazing incidence. In another aspect of an embodiment of the present invention, a shield is disclosed which is heated to a temperature sufficient to remove one or more species of debris material that has deposited on the shield. In yet another aspect of an embodiment of the present invention, a system is disclosed which a shield is moved from a light source plasma chamber to a cleaning chamber where the shield is cleaned.

    Abstract translation: 公开了用于保护EUV光源等离子体生产室光学元件表面免受等离子体形成产生的碎片的系统和方法。 在本发明的实施例的一个方面,公开了一种屏蔽件,其包括位于光学元件和等离子体形成部位之间的至少一个中空管。 管被定向以捕获碎片,同时允许光以相对较小的掠入射角度的反射通过管的内腔。 在本发明的一个实施例的另一方面,公开了一种屏蔽件,其被加热到足以去除沉积在屏蔽上的一种或多种碎屑材料的温度。 在本发明的一个实施例的另一方面,公开了一种系统,其将屏蔽件从光源等离子体室移动到清洁室,其中屏蔽件被清洁。
