Open-frame XY-Rotary stages designed with a low profile for wafer handling and many other automated accurate positioning applications in semiconductor manufacturing industries. XY drive mechanism located on the side of the unit and large center hole-through rotary table offer a clear unobstruced access to the wafer.
