    摘要： A method of ensuring against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents interaction between any fluorine that is released during the refractory material deposition step from interacting with the underlying silicide.

    摘要： A method and structure for reducing the corrosion of the copper seed layer during the fabrication process of a semiconductor structure. Before the structure (or the wafer containing the structure) exits the vacuum environment of the sputter tool, the structure is warmed up to a temperature above the water condensation temperature of the environment outside the sputter tool. As a result, water vapor would not condense on the structure when the structure exits the sputter tool, and therefore, corrosion of the seed layer by the water vapor is prevented. Alternatively, a protective layer resistant to water vapor can be formed on top of the seed layer before the structure exits the sputter tool environment. In yet another alternative embodiment, the seed layer can comprises a copper alloy (such as with aluminum) which grows a protective layer resistant to water vapor upon exposure to water vapor.

    摘要： A semiconductor device and a method of fabricating the same, includes vertically stacked layers on an insulator. Each of the layers includes a first dielectric insulator portion, a first metal conductor embedded within the first dielectric insulator portion, a first nitride cap covering the first metal conductor, a second dielectric insulator portion, a second metal conductor embedded within the second dielectric insulator portion, and a second nitride cap covering the second metal conductor. The first and second metal conductors form first vertically stacked conductor layers and second vertically stacked conductor layers. The first vertically stacked conductor layers are proximate the second vertically stacked conductor layers, and at least one air gap is positioned between the first vertically stacked conductor layers and the second vertically stacked conductor layers. An upper semiconductor layer covers the first vertically stacked conductor layers, the air gap and the second plurality of vertically stacked conductor layers.
