Abstract: A contact for providing a connection to a substrate in a substrate plating system includes a body having an arcuate shape. The arcuate shape of the body is configured to conform to a shape of at least a portion of a substrate arranged on a lip seal and a cup of the substrate plating system. A plurality of first contact fingers extend a first distance from the body. A plurality of second contact fingers extend a second distance from the body. The first distance is greater than the second distance.

Abstract: A wetting tool that provides improved wettability and debris removal from features defined by a patterned resist layer on a substrate. The substrate wetting tool relies on a wetting solution having a pH of 2.0 or less and/or a temperature ranging from 20 to 50° C. With a pH of 2.0 or less, the resist material used to form features chemically reacts, making it more hydrophilic. The wetting solution is therefore attracted into the features, beneficially reducing the chance of bubble formation and removing debris. At elevated temperatures, the heated wetting solution improves particle de-lamination and aids in dissolving debris and oxides from the substrate surface.

Abstract: Described are apparatus and methods for electroplating one or more metals onto a substrate. Embodiments include electroplating apparatus configured for plating highly uniform metal layers. In specific embodiments, the apparatus includes a flow-shaping element made of an ionically resistive material and having a plurality of channels made through the flow shaping element. The channels allow for transport of the electrolyte through the flow shaping element during electroplating. The channel openings are arranged in a spiral-like pattern on the substrate-facing surface of the flow shaping element such that the center of the spiral-like pattern is offset from the center of the flow shaping element.

Abstract: An intermetal dielectric structure for integrated circuits is provided having a premetal dielectric and a metal line thereon, with a SRO liner on the premetal dielectric layer and the metal lines, a FGS dielectric layer over the SRO liner, a SRO film over the FGS dielectric layer, and a TEOS dielectric layer over the SRO film. Vias through the FGS dielectric layer are treated to have fluorine-free regions around the vias. The structure is not subject to fluorine attack on the metal lines or vias while having a stable FGS dielectric layer with less fluorine out-gassing and out-diffusion.
