    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: A device and method of forming fluoride metal barriers at an interface of a fluorinated low-K dielectric and Cu or Cu alloy interconnects is disclosed. The fluoride metal barriers may prevent interconnects from reacting with the fluorinated low-K dielectric. The method may include depositing a thin film of metal or metal alloy on the fluorinated low-K dielectric. The thin film may include a metal or metal alloying element that reacts with free fluorine and/or fluorine compounds from the fluorinated low-K dielectric to form fluoride metal barriers.

    摘要: A metal oxide sensor is provided on a semiconductor substrate to provide on-chip sensing of gases. The sensor may include a metal layer that may have pores formed by lithography to be of a certain width. The top metal layer may be oxidized resulting in a narrowing of the pores. Another metal layer may be formed over the oxidized layer and electrical contacts may be formed on the metal layer. The contacts may be coupled to a monitoring system that receives electrical signals indicative of gases sensed by the metal oxide sensor.

    摘要: Cu interconnect structures using a bottomless liner to reduce the copper interfacial electron scattering and lower the electrical resistance are described in this application. The interconnect structures comprise a nucleation layer and a liner layer that may be formed by an oxide or nitride. The bottom portion of the liner layer is removed to expose the nucleation layer. Since the liner is bottomless, the nucleation layer is exposed during Cu deposition and serves to catalyze copper nucleation and enable selective growth of copper near the bottom (where the nucleation layer is exposed), rather than near the liner sidewalls. Thus, copper may be selectively grown with a bottom-up fill behavior than can reduce or eliminate formation of voids. Other embodiments are described.
