Patent ID: 7573054

Claim:
An edge exposure apparatus for exposing an edge portion of a substrate having a photosensitive thin film formed thereon by a light source for exposure, comprising: a first optical path forming member and a second optical path forming member with respective inlet sides arranged within light beams from said light source; a first mounting table configured to be rotatable about a vertical axis while mounting the substrate thereon, and provided such that the edge portion of the substrate is located within an application region of the light beams from an outlet side of said first optical path forming member; a second mounting table configured to be rotatable about a vertical axis while mounting the substrate thereon, and provided such that the edge portion of the substrate is located within an application region of the light beams from an outlet side of said second optical path forming member; and a light blocking means for blocking application of light from each of said first optical path forming member and said second optical path forming member, wherein said light blocking means has a first shutter for blocking an optical path formed by said first optical path forming member and a second shutter for blocking an optical path formed by said second optical path forming member, wherein each of said first optical path forming member and said second optical path forming member has a light guide rod and a lens for condensing light from said light guide rod, and wherein each of said first shutter and said second shutter is provided between said light guide rod and said lens.
