    摘要: The present invention is related to a method for forming vertical conductive structures by electroplating. Specifically, a template structure is first formed, which includes a substrate, a discrete metal contact pad located on the substrate surface, an inter-level dielectric (ILD) layer over both the discrete metal contact pad and the substrate, and a metal via structure extending through the ILD layer onto the discrete metal contact pad. Next, a vertical via is formed in the template structure, which extends through the ILD layer onto the discrete metal contact pad. A vertical conductive structure is then formed in the vertical via by electroplating, which is conducted by applying an electroplating current to the discrete metal contact pad through the metal via structure. Preferably, the template structure comprises multiple discrete metal contact pads, multiple metal via structures, and multiple vertical vias for formation of multiple vertical conductive structures.

    摘要: Techniques for electrodepositing selenium (Se)-containing films are provided. In one aspect, a method of preparing a Se electroplating solution is provided. The method includes the following steps. The solution is formed from a mixture of selenium oxide; an acid selected from the group consisting of alkane sulfonic acid, alkene sulfonic acid, aryl sulfonic acid, heterocyclic sulfonic acid, aromatic sulfonic acid and perchloric acid; and a solvent. A pH of the solution is then adjusted to from about 2.0 to about 3.0. The pH of the solution can be adjusted to from about 2.0 to about 3.0 by adding a base (e.g., sodium hydroxide) to the solution. A Se electroplating solution, an electroplating method and a method for fabricating a photovoltaic device are also provided.

    摘要: 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.
