Abstract: Embodiments of the present invention generally relate to an apparatus for processing a substrate and more specifically to a device that will transfer electrical power and/or control signals between a stationary base and a rotating platen without involving mechanical contact. The device does not suffer the drawbacks of conventional slip rings burdened with moving surfaces. In one embodiment, an apparatus for processing a substrate is provided. The apparatus includes a platen assembly having a surface for supporting a planarizing material and disposed on a stationary base so that the platen assembly may rotate relative to the base. The apparatus further includes a coupling assembly for transferring electrical energy from a primary coil to a secondary coil. The coupling assembly includes the primary coil of wire wrapped around a first core; the first core coupled to the base; the secondary coil of wire wrapped around a second core; and the second core coupled to the platen assembly.
