Abstract
According to one embodiment, there is provided a semiconductor manufacturing apparatus including a rotatable substrate stage, a first measuring mechanism and a second measuring mechanism. On the rotatable substrate stage, a laminated substrate used for manufacturing a semiconductor device is placed. The laminated substrate is formed by a first substrate and a second substrate to be laminated to each other. The first measuring mechanism measures an edge of the first substrate and an edge of the second substrate from a first direction. The second measuring mechanism measures the edge of the first substrate and the edge of the second substrate from a second direction. The second direction is a direction different from the first direction in an angle to a normal of the first substrate.
