发明名称 Method and apparatus for supplying electricity uniformly to a workpiece
摘要 <p>The present invention relates to a device that supplies electricity to a substrate. In one embodiment, the device includes multiple contacts (56), a current sensor, and a current regulator (250). The current sensor is attached to each of the plurality of contacts to sense their electric current. A current regulator (250) controls current applied to each of the multiple contacts (56) in response to the current sensor. In another embodiment, a compliant ridge is formed about the periphery of each contact to seal the contact from undesired chemicals. <IMAGE></p>
