    Abstract: It is a general object of the present invention to provide an improved method of fabrication in the formation of an improved copper metal diffusion barrier layer having the structure, W/WSiN/WN, in single and dual damascene interconnect trench/contact via processing with 0.10 micron nodes for MOSFET and CMOS applications. The diffusion barrier is formed by depositing a tungsten nitride bottom layer, followed by an in situ SiH4/NH3 or SiH4/H2 soak forming a WSiN layer, and depositing a final top layer of tungsten. This invention is used to manufacture reliable metal interconnects and contact vias in the fabrication of MOSFET and CMOS devices for both logic and memory applications and the copper diffusion barrier formed, W/WSiN/WN, passes a stringent barrier thermal reliability test at 400° C. Pure single barrier layers, i.e., single layer WN, exhibit copper punch through or copper spiking during the stringent barrier thermal reliability test at 400° C.

    Abstract: A method for forming a semiconductor structure. A semiconductor substrate including a plurality of dies mounted thereon is provided. The substrate includes a first portion proximate to the dies and a second portion distal to the dies. In some embodiments, the first portion may include front side metallization. The second portion of the substrate is thinned and a plurality of conductive through substrate vias (TSVs) is formed in the second portion of the substrate after the thinning operation. Prior to thinning, the second portion may not contain metallization. In one embodiment, the substrate may be a silicon interposer. Further back side metallization may be formed to electrically connect the TSVs to other packaging substrates or printed circuit boards.
