Abstract

A wafer transfer system is described for transferring a wafer while at substantially the same time another wafer is being processed. The wafer transfer system comprises, in one embodiment, a transfer chamber having a wafer transfer blade, a load lock chamber coupled to the transfer chamber, a robot for loading and unloading the wafer into the load lock chamber, and a slider coupled to the wafer transfer blade for moving the wafer transfer blade between the transfer chamber and the load lock chamber. According to a preferred embodiment, the slider utilizes a magnetic coupling mechanism.
