    摘要: A structure formed in an opening having a substantially vertical sidewall defined by a non-metallic material and having a substantially horizontal bottom defined by a conductive pad, the structure including a diffusion barrier covering the sidewall and a fill composed of conductive material. The structure including a first intermetallic compound separating the diffusion barrier from the conductive material, the first intermetallic compound comprises an alloying material and the conductive material, and is mechanically bound to the conductive material, the alloying material is at least one of the materials selected from the group of chromium, tin, nickel, magnesium, cobalt, aluminum, manganese, titanium, zirconium, indium, palladium, and silver; and a first high friction interface located between the diffusion barrier and the first intermetallic compound and parallel to the sidewall of the opening, wherein the first high friction interface results in a mechanical bond between the diffusion barrier and the first intermetallic compound.

    摘要: The present invention provides a method to form deep features in a stacked semiconductor structure. Deposition of a non-conformal hardmask onto a patterned topography can form a hardmask to protect all but recessed areas with minimal integration steps. The invention enables etching deep features, even through multiple BEOL layers, without multiple additional process steps.
