Claim 7:
8. 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;
where the first and second electromagnetic actuators are each configured to produce horizontal forces between the first device and the first guide in a first direction, and the apparatus further comprises a fourth electromagnetic actuator and a fifth electromagnetic actuator proximate respective third and fourth corners of three sides of the first device, where the fourth and fifth electromagnetic actuators are each configured to produce horizontal forces between the first device and the second guide in an opposite second direction.
