Abstract:
An exposure method and a scanning-type aligner which are used in a photolithography method for the manufacture of liquid crystal display device, etc., particularly, an exposure method and a scanning-type aligner which are suitable for the exposure of a substrate deformed in the manufacturing process and, more particularly, an exposure method and a scanning-type aligner which enable the precise alignment of the deformed substrate. A scanning-type aligner by which a mask (5) having a pattern and a plate (4) are synchronously transferred and the pattern of the mask (5) is exposed onto the plate (4) has alignment microscopes (1 and 2) which detect the deformation of the shape of the plate (4) and a controller (13) which corrects the relative position between the mask (5) and the plate (4) during the transfer in accordance with the detection result.
