Abstract:
1. Plating apparatus comprising: a plating bath; one or more elongated arms for holding one or more substrates within said plating bath; an electrically conductive cruciform coupled to said one or more elongated arms such that said electrically conductive cruciform causes said one or more elongated arms to rotate about the axis of rotation of said electrically conductive cruciform; a first rotating gear coupled to said electrically conductive cruciform such that rotation of said first rotating gear causes said electrically conductive cruciform to rotate about the axis of rotation of said first rotating gear, said first rotating gear having an electrically conductive region electrically coupled to said electrically conductive cruciform, said electrically conductive cruciform being electrically coupled to at least one of said one or more elongated arms, said at least one of said one or more elongated arms being electrically conductive and electrically coupled to said one or more substrates; a second rotating gear driven by a rotor of a motor; a third rotating gear driven by said second rotating gear and driving said first rotating gear; a non-rotating gear; a fourth rotating gear coupled to said cruciform and engaging with said non-rotating gear to thereby impart planetary motion to said cruciform; and an electrically conductive path having a first end extending outside the plating bath and a second end coupled to said electrically conductive region.
