Abstract:
1. An exposure device exposing an exposure pattern to a substrate, comprising: detecting means for detecting undulation or thickness unevenness each extending in a first direction on a surface of a substrate; retaining means for supporting the substrate, the retaining means including, support mechanisms configured to be elongated in a second direction orthogonal to the first direction of the undulation or thickness unevenness detected by the detecting means, the support mechanisms being arranged in the first direction of the undulation or thickness unevenness, and support mechanism adsorbing plates configured to be independently displaced in a third direction of displacement orthogonal to the surface of the substrate; and a plurality of adsorbing means for adsorbing and retaining the substrate provided on the retaining means of the support mechanisms along a length direction of the support mechanisms.
