Abstract
A semiconductor manufacturing apparatus includes a semiconductor package. A tray has the semiconductor package seated thereon. An inspector inspects an alignment state of the semiconductor package. A protrusion is on a top surface of the tray and extends in a Z direction that is a vertical direction. The protrusion surrounds a side surface of the semiconductor package when the semiconductor package is in an aligned state. The semiconductor package overlaps at least a portion of the protrusion in the Z direction when the semiconductor package is in a misaligned state. An under vision camera detects a rotation angle of the semiconductor package with respect to an X-Y plane defined in a first horizontal direction X and a second horizontal direction Y that cross the Z direction. A picker moves the semiconductor package between the tray and an area above the under vision camera.
