Abstract:
A maskless lithographic apparatus may include a light source providing an exposure beam, a light modulator modulating the exposure beam according to an exposure pattern, an exposure optical system delivering the modulated exposure beam provided by the light modulator onto a substrate in a form of a beam spot array, and a control unit switching off some rows in the beam spot array in order to make exposure energy distribution uniform across the beam spot array. A method for compensating for an alignment error using a maskless lithographic apparatus may include providing an exposure beam, modulating the exposure beam according to an exposure pattern, delivering the modulated exposure beam provided by a light modulator onto a substrate in a form of a beam spot array, and switching off some rows in the beam spot array in order to make exposure energy distribution uniform across the beam spot array.
