    • The invention relates to an electron beam exposure apparatus for transferring a pattern onto the surface of a target (14), comprising: a beamlet generator for generating a plurality of electron beamlets (5a, 5b); a modulation array for receiving said plurality of electron beamlets, comprising a plurality of modulators for modulating the intensity of an electron beamlet; a controller, connected to the modulation array for individually controlling the modulators, an adjustor, operationally connected to each modulator, for individually adjusting the control signal of each modulator; a focusing electron optical system comprising an array of electrostatic lenses (7) wherein each lens focuses a corresponding individual beamlet, which is transmitted by said modulation array, to a cross section smaller than 300 nm, and a target holder for holding a target with its exposure surface onto which the pattern is to be transferred in the first focal plane of the focusing electron optical system.
    • 本发明涉及一种用于将图案转印到目标(14)的表面上的电子束曝光装置,包括:用于产生多个电子束(5a,5b)的小波发生器; 用于接收所述多个电子子束的调制阵列,包括用于调制电子束的强度的多个调制器; 连接到用于单独控制调制器的调制阵列的控制器,可操作地连接到每个调制器的调节器,用于单独调整每个调制器的控制信号; 一种聚焦电子光学系统,包括静电透镜阵列(7),其中每个透镜将由所述调制阵列传输的相应的单独子束聚焦到小于300nm的横截面,以及用于保持目标的靶保持器 在聚焦电子光学系统的第一焦平面中将图案转印到其上的曝光表面。
