    • The invention relates to a maskless lithographic apparatus (1), comprising: a light modulator (7) having a plurality of micromirrors arranged in a micromirror array for modulating an exposure beam (5) according to an exposure pattern, and an exposure optical system (8) for delivering the modulated exposure beam (5) onto a substrate (2). The apparatus (1) comprises a tilt error compensation unit (15) for compensating for tilt errors of the micromirrors of the micromirror array. The invention also relates to a corresponding method for generating an exposure pattern on a substrate (2), comprising: modulating an exposure beam (5) according to the exposure pattern using a plurality of micromirrors of a micromirror array, and delivering the modulated exposure beam (5) onto a substrate (2) in the form of a beam-spot array (40), wherein at least one of the modulating step and the delivering step comprises compensating for tilt errors of the micromirrors of the micromirror array.
    • 本发明涉及一种无掩模光刻设备(1),包括:光调制器(7),其具有布置在微镜阵列中的多个微镜,用于根据曝光图案调制曝光光束(5),以及曝光光学系统 8),用于将调制的曝光束(5)输送到衬底(2)上。 装置(1)包括用于补偿微镜阵列的微镜的倾斜误差的倾斜误差补偿单元(15)。 本发明还涉及用于在衬底(2)上产生曝光图案的相应方法,包括:使用多个微镜阵列的微镜根据曝光图案调制曝光光束(5),并且传送经调制的曝光光束 (5)以束 - 点阵列(40)的形式存在于衬底(2)上,其中调制步骤和传送步骤中的至少一个包括补偿微镜阵列的微镜的倾斜误差。
