摘要:
A method of forming an interconnect structure and an integrated circuit including the interconnect structure. The method includes: depositing a dielectric layer over a conductive layer; forming an opening in the dielectric layer to expose the conductive layer; forming a barrierless single-phase interconnect comprising a metal or compound having a melting point between a melting point of copper and a melting point of tungsten. Forming includes depositing a layer of metal or compound within the opening and on an upper surface of the dielectric layer Preferably, the barrierless single-phase interconnect comprises cobalt or a cobalt containing compound. Thus, an interconnect structure, including a via and associated line, is made up of a single-phase metal or compound without the use of a different material between the interconnect and the underlying dielectric, thus improving electrical performance and reliability and further simplifying the interconnect formation process.

摘要:
Methods for making copper (Cu) interconnects in semiconductor devices for interconnect dimensions less than 50 nm are described. The processes form Cu interconnects using a sequence of barrier layer, liner layer, and Cu deposition layer depositions, followed by a thermally assisted Cu reflow of the Cu deposition layer, and then a chemical mechanical polish (CMP) to removed excess portions of the reflowed Cu. The liner layer comprises noble metals such as Ru, Ir, Os, Rh, Re, Pd, Pt, and Au. Such processes avoids the formation of voids in copper interconnects with dimensions less than 50 nm.
摘要:
Disclosed are embodiments of a method of forming metal interconnects using a sacrificial layer to protect a seed layer prior to metal gap fill. The sacrificial layer can prevent oxidation of the seed layer and perhaps oxygen migration to an underlying barrier layer. Other embodiments are described and claimed.
