Abstract:
1. An exposure method for forming different resist patterns in a first region and a second region on a single substrate, the method comprising: fixing a photomask with respect to a light source, the photomask having a first mask pattern for exposing a portion of the resist pattern in the first region, and a second mask pattern for exposing a portion of the resist pattern in the second region; continuously or intermittently exposing the resist in the first region by selectively directing a light beam from the light source to the first mask pattern, while transferring the substrate; and continuously or intermittently exposing the resist in the second region by selectively directing the light beam from the light source to the second mask pattern, while transferring the substrate, wherein when exposing the resist in the second region, the light beam from the light source is deflected by a pair of mirrors to move the irradiation position of light on the photomask from the position where the first mask pattern is formed to the position where the second mask pattern is formed.
