Classification: CPC H | IPC H

Claim 0:
1. A semiconductor manufacturing apparatus comprising:
a rotatable substrate stage on which a laminated substrate used for manufacturing a semiconductor device is placed, the laminated substrate being formed by a first substrate and a second substrate to be laminated to each other;
a first measuring mechanism that measures an edge of the first substrate and an edge of the second substrate in a first direction;
a second measuring mechanism that measures the edge of the first substrate and the edge of the second substrate in a second direction, the second direction being a direction different from the first direction in an angle to a normal of the first substrate; and
a controller configured to determine a center position of the first substrate and a center position of the second substrate according to a measurement result of the first measuring mechanism and a measurement result of the second measuring mechanism.
