Abstract: A trench contact silicide is formed on an inner wall of a contact trench that reaches to a buried conductive layer in a semiconductor substrate to reduce parasitic resistance of a reachthrough structure. The trench contact silicide is formed at the bottom, on the sidewalls of the trench, and on a portion of the top surface of the semiconductor substrate. The trench is subsequently filled with a middle-of-line (MOL) dielectric. A contact via may be formed on the trench contact silicide. The trench contact silicide may be formed through a single silicidation reaction with a metal layer or through multiple silicidation reactions with multiple metal layers.

Abstract: An array of through substrate vias (TSVs) is formed through a semiconductor substrate and a contact-via-level dielectric layer thereupon. A metal-wire-level dielectric layer and a line-level metal wiring structure embedded therein are formed directly on the contact-via-level dielectric layer. The line-level metal wiring structure includes cheesing holes that are filled with isolated portions of the metal-wire-level dielectric layer. In one embodiment, the entirety of the cheesing holes is located outside the area of the array of the TSVs to maximize the contact area between the TSVs and the line-level metal wiring structure. In another embodiment, a set of cheesing holes overlying an entirety of seams in the array of TSVs is formed to prevent trapping of any plating solution in the seams of the TSVs during plating to prevent corrosion of the TSVs at the seams.
