    摘要: Described are doped TaN films, as well as methods for providing the doped TaN films. Doping TaN films with Ru, Cu, Co, Mn, Al, Mg, Cr, Nb, Ti and/or V allows for enhanced copper barrier properties of the TaN films. Also described are methods of providing films with a first layer comprising doped TaN and a second layer comprising one or more of Ru and Co, with optional doping of the second layer.

    摘要: Embodiments of the invention generally provide a method of forming an air gap between conductive elements of a semiconductor device, wherein the air gap has a dielectric constant of approximately 1. The air gap may generally be formed by depositing a sacrificial material between the respective conductive elements, depositing a porous layer over the conductive elements and the sacrificial material, and then stripping the sacrificial material out of the space between the respective conductive elements through the porous layer, which leaves an air gap between the respective conductive elements. The sacrificial material may be, for example, a polymerized alpha terpinene layer, the porous layer may be, for example, a porous carbon doped oxide layer, and the stripping process may utilize a UV based curing process, for example.
