DEVICE FOR PARTICLE FREE HANDLING OF SUBSTRATES
Abstract:
A device for particle free handling of substrates of micro technology within mini environments under clean room conditions works friction free and thus particle free. One component of the device is movable relative to an other component in at least the x-, y-, z-axes and a Φ-direction and supported and driven along each of the axes and the direction contactless electromagnetically. Transmission of energy for bearing and driving the one component is effected contactless. The device includes at least one active component and at least one passive component. A movable active component may be guided on the fixed passive component by a magnet bearing, and a drive motor which rides with the active component may be coupled with an energy supply over an electromagnetic coupling.
