A method of forming an inductor. The method includes: forming a dielectric layer on a substrate; forming a lower trench in the dielectric layer; forming a liner in the lower trench and on the dielectric layer; forming a Cu seed layer over the liner; forming a resist layer on the Cu seed layer; forming an upper trench in the resist layer; electroplating Cu to completely fill the lower trench and at least partially fill the upper trench; removing the resist layer; selectively forming a passivation layer on all exposed Cu surfaces; selectively removing the Cu seed layer from regions of the liner; and removing the thus exposed regions of the liner from the dielectric layer, wherein a top surface of the inductor extends above a top surface of the dielectric layer, the passivation layer remaining on regions of sidewalls of the inductor above the top surface of the dielectric layer.

Methods for electrodepositing germanium on various semiconductor substrates such as Si, Ge, SiGe, and GaAs are provided. The electrodeposited germanium can be formed as a blanket or patterned film, and may be crystallized by solid phase epitaxy to the orientation of the underlying semiconductor substrate by subsequent annealing. These plated germanium layers may be used as the channel regions of high-mobility channel field effect transistors (FETs) in complementary metal oxide semiconductor (CMOS) circuits.

An electroplating apparatus and method for depositing a metallic layer on the surface of a wafer is provided wherein said apparatus and method do not require physical attachment of an electrode to the wafer. The surface of the wafer to be plated is positioned to face the anode and a plating fluid is provided between the wafer and the electrodes to create localized metallic plating. The wafer may be positioned to physically separate and lie between the anode and cathode so that one side of the wafer facing the anode contains a catholyte solution and the other side of the wafer facing the cathode contains an anolyte solution. Alternatively, the anode and cathode may exist on the same side of the wafer in the same plating fluid. In one example, the anode and cathode are separated by a semi permeable membrane.

A plating method can form a plated film having a uniform thickness over the entire surface, including the peripheral surface, of a substrate. The plating method includes: disposing an anode so as to face a conductive film, formed on a substrate, which serves as a cathode, and disposing an auxiliary cathode on an ring-shaped seal member for sealing a peripheral portion of the substrate; bringing the conductive film, the anode and the auxiliary cathode into contact with a plating solution; and supplying electric currents between the anode and the conductive film, and between the anode and the auxiliary cathode to carry out plating.
