    Abstract: Semiconductor devices and methods for fabricating the same. An exemplary device includes a substrate, a dielectric layer, a protection layer, and a conformal barrier layer. The dielectric layer overlies the substrate and comprises an opening. The opening comprises a lower portion and a wider upper portion, exposing parts of the substrate. The bottoms of the upper portion act as shoulders of the opening. The protection layer overlies at least one shoulder of the opening. The conformal barrier layer is disposed in the opening and overlies the protection layer and the dielectric layer, wherein etching resistance of the protection layer against inert-gas plasma is higher than that of the barrier layer.

    Abstract: Via structure and process flow for interconnection in a semiconductor product. A bottom metal layer is provided to represent a connection layer in the semiconductor product. An isolation layer on the bottom metal layer comprises a via hole exposing a portion of the bottom metal layer. The via hole comprises a sidewall and a bottom. A first barrier metal layer is disposed on the sidewall of the via hole, but not on the bottom of the via hole. A metal under-layer is formed on the bottom of the via hole and on the first barrier metal layer. A second barrier metal layer is formed on the metal under-layer. A metal fill layer fills the via hole. A lattice mismatch between the metal under-layer and the second barrier metal layer is less than about 5%.

    Abstract: A method of electroplating a metal layer on a semiconductor device includes a sequence of biasing operations that includes a first electroplating step at a first current density followed by a second immersion step at a second current density being less than the first current density, and subsequent electroplating steps of increasing current densities beginning with a third electroplating step having a third current density that is greater than the first current density. The second, low current density immersion step improves the quality of the plating process and produces a plated film that completely fills openings such as vias and trenches and avoids hollow vias and pull-back on the bottom corners of via and trench openings. The low current density second immersion step produces an electrochemical deposition process that provides low contact resistance and therefore reduces device failure.
