Abstract:
1. An apparatus for fabricating a semiconductor device which has a first circuit pattern of the semiconductor device including a first mark and a second mark, using a mask with at least part of a second circuit pattern of the semiconductor device including a third mark corresponding to the first mark and a fourth mark corresponding to the second mark, comprising: a particle direction collimating unit aligning the first mark with the third mark and the second mark with the fourth mark, and selectively irradiating the particles to the substrate using the mask; and an angle adjustment unit changing a relative angle between the substrate and the mask and in response to a dimensional difference between a first length from the first mark to the second mark and a second length from the third mark to the fourth mark so that the dimensional difference is canceled.
