摘要:
In a lithographic apparatus, a scanning mechanism is coarse compared with precise patterns to be exposed onto a substrate. In order to ensure that the image and the substrate are aligned at some point in time, an oscillation is imparted to either the substrate table, or to a device that aligns the image, such as a mask table. The oscillation frequency is chosen to compliment a maximum alignment error. The frequency of a radiation pulse is arranged to coincide with the image and the substrate being most accurately aligned. The radiation pulse of the image may be timed to coincide with the alignment without the use of the imparted oscillation.
