Abstract: A maskless exposure device includes: a light source for emitting a beam, a light modulator for modulating the beam according to an exposure pattern, an optical system for transferring the modulated beam onto a substrate in the form of a beam spot array, a position determining unit for generating relative position data between the beam spot array and the substrate, and a control unit for controlling the light modulator based on the position data of the position determining unit.
The beam spot array includes alignment areas and out-of-alignment areas which are alternately disposed, on/off-spots which overlap the alignment areas, and neutral spots which overlap the out-of-alignment areas and at which the substrate is not irradiated with the beam, and a distance between on/off-spots adjacent to each other at a first point in time is different from a distance between on/off-spots adjacent to each other at a second point in time.
