ABSTRACT:
A squeegee unit is driven to rotate about a rotation axis perpendicular to a glass substrate surface with a motor while a plurality of blades of the squeegee unit contact on the substrate surface. The rotating squeegee unit is moved in a predetermined path on the substrate surface by relatively moving an X-Y stage so that its blades remove foreign materials adhered to the glass substrate surface.
