    Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a wiring layer in an integrated circuit structure.
    SOLUTION: An organic insulating layer is formed, the insulating layer is patterned, a liner is accumulated on the insulating layer, the above structure is exposed in plasma, and a pore is formed in an insulating layer of an area adjacent to the liner. The liner is formed sufficiently thin so that plasma penetrates the liner and the pore is formed on the insulating layer without influencing the liner. During the plasma processing, the plasma penetrates the liner without influencing the liner. After the plasma processing, an additional liner can be accumulated. Thereafter, a conductor is accumulated and an excessive portion of the conductor is deleted from the structure. This method produces an integrated circuit structure including the organic insulating layer having a patterned structure, a liner covering the rear side of the patterned structure, and a conductor filling the patterned structure. The insulating layer includes the pore along the surface area of the insulating layer contacting to the liner, and further, the pore is only existent along the surface area contacting to the liner (where the liner is non-existent inside the pore).

    Abstract: Methods of depositing a tantalum nitride (TaN) diffusion barrier region on low-k materials. The methods include forming a protective layer (104) on the low-k material substrate (102) by performing plasma-enhanced atomic layer deposition (PE-ALD) from tantalum-based precursor and a nitrogen plasma in a chamber. The protective layer (104) has a nitrogen content greater than its tantalum content. A substantially stoichiometric tantalum-nitride layer is then formed by performing PE-ALD from the tantalum-based precursor and a plasma including hydrogen and nitrogen. The invention also includes the tantalum-nitride diffusion barrier region (108) so formed. In one embodiment, the metal precursor includes tantalum penta-chloride (TaC1 5 ). The invention generates a sharp interface between low-k materials and liner materials.

    Abstract: In accordance with one aspect of the invention, a method is provided for fabricating a semiconductor element having a contact via. In such method, a hole (112) can be formed in a dielectric layer (120) to at least partially expose a region (108) including at least one of semiconductor or conductive material. A seed layer (143) can be deposited over a major surface (118) of the dielectric layer and over a surface within the hole (112). In one embodiment, the seed layer (143) can include a metal selected from the group consisting of iridium, osmium, palladium, platinum, rhodium, and ruthenium. A layer (132) consisting essentially of cobalt can be electroplated over the seed layer (143) within the hole (112) to form a contact via (110) in electrically conductive communication with the region.

    Abstract: A method of fabricating a FinFET 200 is disclosed which comprises the steps of forming a plurality of fins on a dielectric substrate. A gate layer (208, figure 2A) is deposited over the fins. In some embodiments the fin hardmask that is present on the tops of each fin is removed from some of the fins prior to the deposition of the gate layer. A gate hardmask (210) is then deposited over the gate layer. A portion of the gate hardmask layer and gate layer are then removed. In some embodiments this removal step also removes portions of the fins underneath. In other embodiments portions 202A, 202B, 202C of a subset of fins are removed with an etch. The portion of the etched sacrificial fins that remain are called finlets 220. These finlets remain under the gate of the FinFET. In some embodiments the remaining fins are subsequently merged together.

    Abstract: Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a capping layer and a dielectric layer. The dielectric layer is patterned so as to expose the capping layer. The capping layer is then sputter etched to remove the capping layer and expose the metal conductor. In the process of sputter etching, the capping layer is redeposited onto the sidewall of the pattern. Lastly, at least one layer is deposited into the pattern and covers the redeposited capping layer.
