    • In a charged-particle exposure apparatus (100) for exposure of a target (41) with a beam of electrically charged particles, the illumination system (101) comprises a deflector means (401) adapted to vary the direction of incidence of the illuminating beam upon the pattern definition means, the pattern definition means (20) forms the shape of the illuminating beam into a desired pattern, and the projection optics system (103) projects an image of the beam shape defined in the pattern definition means onto the target (41); the projection optics system comprises a blocking aperture means (204) having an opening and being adapted to block passage of beams traversing outside said opening, namely when the deflector means (401) is activated to tilt the beamlet by a sufficient angle from its non-deflected path, e.g., for blanking out during the process of loading a pattern into the pattern definition means.
    • 在用于用带电粒子束照射目标(41)的带电粒子曝光装置(100)中,照明系统(101)包括偏转装置(401),该偏转装置适于改变照明光束的入射方向 在图案定义装置上,图案定义装置(20)将照明光束的形状形成为期望的图案,并且投影光学系统(103)将在图案定义装置中限定的光束形状的图像投射到目标( 41); 投影光学系统包括具有开口的阻挡孔口装置(204),并且适于阻挡穿过所述开口外侧的梁的通过,即当偏转装置(401)被启动以使子束从其非易失性位置倾斜足够的角度时, 偏转路径,例如,在将图案加载到图案定义装置的过程中用于消隐。
