    Abstract: A method for utilizing electroless copper deposition to form interconnects on a semiconductor. Once a via or a trench is formed in a dielectric layer, a titanium nitride (TiN) or tantalum (Ta) barrier layer is deposited. Then, a catalytic copper seed layer is conformally blanket deposited in vacuum over the barrier layer. Next, without breaking the vacuum, an aluminum protective layer is deposited onto the catalytic layer to encapsulate and protect the catalytic layer from oxidizing. An electroless deposition technique is then used to auto-catalytically deposit copper on the catalytic layer. The electroless deposition solution dissolves the overlying protective layer to expose the surface of the underlying catalytic layer. The electroless copper deposition occurs on this catalytic surface, and continues until the via/trench is filled. Subsequently, the copper and barrier material are polished by an application of chemical-mechanical polishing (CMP) to remove excess copper and barrier material from the surface, so that the only copper and barrier material remaining are in the via/trench openings. Then an overlying silicon nitride (SiN) layer is formed above the exposed copper in order to form a dielectric barrier layer. The copper interconnect is fully encapsulated from the adjacent material by the TiN (or Ta) barrier layer and the overlying SiN layer.

    Abstract: Stabilized whole grain flours having a fine particle size and which exhibit good baking functionality are produced with high throughput using two bran and germ fractions and an endosperm fraction. One bran and germ fraction is a coarse fraction which is subjected to two stage grinding, but the second bran and germ fraction is a low ash, fine bran and germ fraction which is sufficiently fine so that it does not need to be subjected to grinding thereby reducing starch damage and increasing production with reduced grinding equipment load. Portions of the coarse bran and germ fraction which are ground in the first grinding stage to a sufficient fineness are separated out and not subjected to additional grinding further reducing starch damage and increasing production. The bran and germ fractions may be combined, subjected to stabilization, and combined with the endosperm fraction to obtain a stabilized whole grain flour.

    Abstract: A light emitting diode (LED) system implements a power management technique. The LED system includes a plurality of LED drivers connected in series, each LED driver configured to regulate the current flowing through a corresponding subset of a plurality of LED strings. Each LED driver determines the tail voltages of the one or more LED strings of the corresponding subset. Each LED driver, except for the first LED driver in the series, also receives a voltage representative of the minimum tail voltage of the other subsets regulated by the upstream LED drivers. Each LED driver then provides the lowest of the voltage received from the upstream LED driver and the one or more tail voltages of the corresponding subset to the downstream LED driver. In this manner a voltage representative of the minimum tail voltage of the plurality of LED strings is cascaded through the series. A feedback controller monitors the minimum tail voltage represented by this cascaded voltage and accordingly adjusts an output voltage provided to the head ends of the plurality of LED strings.
