During exposure of a stripe the stage moves at a constant speed. Each stripe thus includes a certain movement overhead for acceleration and deceleration. As the stripes get shorter, this overhead becomes more significant, and the normal writing speed is no longer achieved. For smaller samples, the writing speed of Aligner: Maskless 02 drops below the specified writing speed for a full 100 x 100 mm substrate. | During exposure of a stripe the stage moves at a constant speed.
