Claim 8:
9. An apparatus comprising:
a first device configured to support a substrate thereon;
a first transport having the first device connected thereto, where the first transport is configured to support the first device for movement along a horizontal path, where the first transport comprises:
at least two guides;
a magnetic system configured to vertically space the first device over the at least two guides with a gap between the first device and the at least two guides, where the magnetic system comprises a first electromagnetic actuator at a first corner of a first side of the first device, a second electromagnetic actuator at a second corner of the first side of the first device, and a third electromagnetic actuator at a second opposite side of the first device, where the third electromagnetic actuator is not located proximate a corner of three sides of the first device; and
a linear actuator configured to move the first device in the path along the at least two guides;
