    摘要: The present invention provides an interconnect structure (of the single or dual damascene type) and a method of forming the same, in which a dense (i.e., non-porous) dielectric spacer is present on the sidewalls of a dielectric material. More specifically, the inventive structure includes a dielectric material having a conductive material embedded within at least one opening in the dielectric material, wherein the conductive material is laterally spaced apart from the dielectric material by a diffusion barrier, a dense dielectric spacer and, optionally, an air gap. The presence of the dense dielectric spacer results in a hybrid interconnect structure that has improved reliability and performance as compared with existing prior art interconnect structures which do not include such dense dielectric spacers. Moreover, the inventive hybrid interconnect structure provides for better process control which leads to the potential for high volume manufacturing.

    摘要: Disclosed are embodiments of an improved high aspect ratio electroplated metal structure (e.g., a copper or copper alloy interconnect, such as a back end of the line (BEOL) or middle of the line (MOL) contact) in which the electroplated metal fill material is free from seams and/or voids. Also, disclosed are embodiments of a method of forming such an electroplated metal structure by lining a high aspect ratio opening (e.g., a high aspect ratio via or trench) with a metal-plating seed layer and, then, forming a protective layer over the portion of the metal-plating seed layer adjacent to the opening sidewalls so that subsequent electroplating occurs only from the bottom surface of the opening up.

    摘要: A high tensile stress capping layer on Cu interconnects in order to reduce Cu transport and atomic voiding at the Cu/dielectric interface. The high tensile dielectric film is formed by depositing multiple layers of a thin dielectric material, each layer being under approximately 50 angstroms in thickness. Each dielectric layer is plasma treated prior to depositing each succeeding dielectric layer such that the dielectric cap has an internal tensile stress.
