Abstract: A plurality of metal interconnects incorporating dielectric spacers and a method to form such dielectric spacers are described. In one embodiment, the dielectric spacers adjacent to neighboring metal interconnects are discontiguous from one another. In another embodiment, the dielectric spacers may provide a region upon which un-landed vias may effectively land.

Abstract: An out-of-band illumination filter for use in photolithography in the form of a top coat on a photoresist is described. The top coat may used by applying a photoresist to a substrate, applying a top coat to the photoresist to prevent out-of-band illumination from exposing the photoresist, and exposing the photoresist in a lithography tool.

Abstract: Embodiments of the invention provide a method for producing ferroelectric polymer devices (FPMDs) employing conditions that avoid or reduce detrimental impact on the ferroelectric polymer film. For one embodiment, a damascene patterning metallization technique is used. For one embodiment a first metal layer is deposited on a substrate to form the bottom electrode for the FPMD. The first metal layer is capped with a selectively deposited diffusion barrier. A layer of ferroelectric polymer film is then deposited on the first conductive layer. The ferroelectric polymer film is planarized. A second metal layer is deposited on the ferroelectric polymer film layer to form the top electrode of the FPMD. The second metal layer is deposited such that the ferroelectric polymer film is not substantially degraded. For various alternative embodiments the various component processes may be accomplished at temperatures far below those employed in a conventional damascene patterning metallization process.

Abstract: Multiple level interconnect structures and methods for fabricating the interconnect structures are disclosed. The interconnect structures may contain an interconnect line, an electrolessly deposited metal layer formed over the interconnect line, a via formed over the metal layer, and a second interconnect line formed over the via. Often the metal layer contains a cobalt or nickel alloy and provides an etch stop layer for formation of an opening corresponding to the via. The metal layer may provide protection to the underlying interconnect line and may replace a traditional protective dielectric layer. The metal layer is conductive, rather than dielectric, and provides a shunt for passage of electrical current between the via and the interconnect line. Similar metal layers may also be used within the interconnect structures as via liner layers and via plugs.

Abstract: A single step electroplating process for interconnect via fill and metal line formation on a semiconductor substrate is disclosed. In this process, a barrier layer is formed onto a surface of a substrate that has at least one via and then a conductive layer is formed onto the barrier layer. Next, a photoresist layer is applied and patterned on top of the conductive layer. The via plugs and metal lines are then deposited on the substrate simultaneously using an electroplating process. After the electroplating process is completed, the photoresist and the conductive layer between the deposited metal lines are removed. The process provides a simple, economical and highly controllable means of forming metal interconnect systems while avoiding the difficulties associated with depositing and patterning metal by traditional semiconductor fabrication techniques.
