摘要:
A lithographic apparatus and method in which an illumination system supplies a projection beam, a patterning system imparts to the beam a pattern in its cross section, and a projection system projects the patterned beam onto a target portion of a substrate. The projection system comprises an array of lenses spaced from the substrate such that each lens in the array focuses part of the patterned beam onto the substrate. A displacement system causes displacement between the lens array and the substrate. A particle detector detects particles on the substrate which are approaching the lens array. A free working distance control system increases the spacing between the lens array and the substrate in response to detection of a particle. The lens array is moved away from the substrate as the detected particle passes the lens array. Thus damage to the lens array can be avoided.
摘要(中):
一种光刻设备和方法,其中照明系统提供投影光束,图案化系统在其横截面中赋予光束图案,并且投影系统将图案化的光束投射到基板的目标部分上。 投影系统包括与衬底间隔开的透镜阵列,使得阵列中的每个透镜将图案化束的一部分聚焦到衬底上。 位移系统导致透镜阵列和基板之间的位移。 颗粒检测器检测正在接近透镜阵列的基板上的颗粒。 响应于颗粒的检测,自由工作距离控制系统增加了透镜阵列和基板之间的间隔。 当检测到的颗粒通过透镜阵列时,透镜阵列移动离开基板。 因此可以避免对透镜阵列的损坏。
