    Abstract: A subject-matter of the invention is a process for metallization with copper which uses a specific silicide for increasing the adhesion of the copper deposit on a semiconductor substrate. In a microelectronics application, this process exhibits the advantage of being able to be employed in the manufacture of integrated circuits in three dimensions by the "via-last" technique. This is because this technique is temperature-limited. In a photovoltaic application, the process of the invention makes it possible to produce a silicide/nickel stack in one step with a lower thermal budget. The process of the invention comprises a step consisting in applying a rapid heat treatment to a substrate covered with nickel, so as to form, between the nickel layer and the silicon layer, an interposed layer which constitutes a promoter of adhesion between the substrate and the copper and which comprises a silicide of Si M stoichiometry, M representing nickel, said silicide being formed by diffusion of a portion of the nickel into the silicon so as to leave a layer of residual nickel at the surface, the heat treatment being carried out at a temperature of less than 350°C and for a period of time of less than 30 minutes.

    Abstract: Described herein are systems and methods for providing a metallization stack to be used in an integrated circuit (IC) package. The metallization stack includes a via for providing electrical interconnection between a first interconnect and a second interconnect. The via is isolated from each of the first and the second interconnects by a respective barrier layer of an electrically conductive material. Enclosing the via from the interconnects using barrier layers reduces electromigration due to interdiffusion of the materials filling each of the interconnects and the material filling the via. Furthermore, such decoupling the via from the interconnects may allow the use of scaled thin conformal barriers for the interconnects and via, thus improving interconnect resistance, via resistance, and/or RC performance of the interconnect.
