Substrate transport vacuum platform
An apparatus including a first device configured to support at least one substrate thereon; and a first transport having the device connected thereto. The transport is configured to carry the device. The transport includes a plurality of supports which are movable relative to one another along a linear path; at least one magnetic bearing which at least partially couples the supports to one another. A first one of the magnetic bearings includes a first permanent magnet and a second magnet. The first permanent magnet is connected to a first one of the supports. A magnetic field adjuster is connected to the first support which is configured to move the first permanent magnet and/or vary influence of a magnetic field of the first permanent magnet relative to the second magnet.
1. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:
determining a distance between a first support and a second support in a transporter, where a first device configured to support at least one substrate thereon is connected to the first support, where the first device comprises at least one of an articulate robot and a substrate shuttle, where the supports are movable relative to one another along a linear path, where the first and second supports are coupled to each other by a magnetic bearing, where the magnetic bearing comprises a first permanent magnet and a second magnet, where the first permanent magnet is connected to the first support, where the transporter comprises a magnetic field adjuster connected to the first support which is configured to move the first permanent magnet and/or vary influence of a magnetic field of the first permanent magnet relative to the second magnet, where the transporter comprises a device connected thereto; and
controlling the magnetic field adjuster to substantially maintain the distance between the first and second supports.
2. A non-transitory program storage device as in claim 1 where the operations further comprise controlling a heat pump, connected to the first support, to pump heat from the at least one active heat generating component on the first support to the heat radiator of the first support.
3. A method comprising:
determining a distance between a first support and a second support in a transporter, where a first device configured to support at least one substrate thereon is connected to the first support, where the first device comprises at least one of an articulate robot and a substrate shuttle, where the supports are movable relative to one another along a linear path, where the first and second supports are coupled to each other by a magnetic bearing, where the magnetic bearing comprises a first permanent magnet and a second magnet, where the first permanent magnet is connected to the first support, where the transporter comprises a magnetic field adjuster connected to the first support which is configured to move the first permanent magnet and/or vary influence of a magnetic field of the first permanent magnet relative to the second magnet, where the transporter comprises a device connected thereto; and
controlling the magnetic field adjuster to substantially maintain the distance between the first and second supports.
4. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising the method claimed in claim 3 .
5. An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code, where the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform operations comprising the method as claimed in claim 3 .
6. The method of claim 3 where the operations further comprise controlling a heat pump, connected to the first support, to pump heat from the at least one active heat generating component on the first support to the heat radiator of the first support.
7. An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code, where the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform operations comprising:
determining a distance between a first support and a second support in a transporter, where a first device configured to support at least one substrate thereon is connected to the first support, where the first device comprises at least one of an articulate robot and a substrate shuttle, where the supports are movable relative to one another along a linear path, where the first and second supports are coupled to each other by a magnetic bearing, where the magnetic bearing comprises a first permanent magnet and a second magnet, where the first permanent magnet is connected to the first support, where the transporter comprises a magnetic field adjuster connected to the first support which is configured to move the first permanent magnet and/or vary influence of a magnetic field of the first permanent magnet relative to the second magnet, where the transporter comprises a device connected thereto; and
controlling the magnetic field adjuster to substantially maintain the distance between the first and second supports.
8. The apparatus as claimed in claim 7 where the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to control a heat pump, connected to the first support, to pump heat from the at least one active heat generating component on the first support to the heat radiator of the first support.
