Abstract
According to one embodiment, a bonding apparatus includes first and second stages, first and second measuring devices, a stress generator, and a controller. The controller generates a focus map for each deformation amount of the first stage based on a deformation amount of the first stage deformed by the stress generator and the shape of the first substrate held by the deformed first stage. In the alignment processing of the first substrate, when causing the first measuring device to measure an alignment mark arranged on the first substrate held by the first stage, the controller uses a focus setting based on the focus map corresponding to the deformation amount applied to the first stage.
