    摘要: Embodiments of the present disclosure may provide a method of forming an integrated circuit (IC) structure, the method including: forming a doped metal layer within a contact opening in an inter-level dielectric (ILD) material on a conductive region, such that the doped metal layer overlies the conductive region, the doped metal layer including a first metal doped with a second metal; and forming a contact to the conductive region within the contact opening of the ILD material by annealing the doped metal layer such that the second metal diffuses into the ILD material to form an interface liner directly between the annealed doped metal layer and the ILD material, the interface liner formed only on sidewalls of the contact opening and in direct contact with the ILD material and only at an interface of the doped metal layer and the ILD material.

    摘要: Integrated circuits with single core inductors and methods for producing them are provided. Embodiments include forming a trench in a dielectric layer; forming a first metal-oxide hard mask by disposing a metal hard mask and an oxide hard mask over the dielectric layer and in strips in the trench; forming metal line trenches through the first metal-oxide hard mask and into the first dielectric layer on opposite sides of the inductor trench and first vias; filling the first metal line trenches, first vias, and trench; forming another dielectric layer and a second metal-oxide hard mask over the filled trench; forming a second trench through the second metal-oxide hard mask and into the second dielectric layer and second metal line trenches and second vias; and filling the second metal line trenches, second vias, and second trench.
