    Abstract: A method of growing a thin film onto a substrate. A precursor of the film is fed into a reaction space in the form of a vapor phase pulse causing the precursor to adsorb onto the surface of the substrate to form a layer thereof. A catalyst is susequently fed into the reaction space in an amount to substantially convert the layer of the precursor to the desired thin film. The above steps may be repeated to achieve the desired film thickness.

    Abstract: A method of tungsten layer deposition for copper metallization in semiconductor devices includes reacting a tungsten carbonyl compound and a borane compound using a cyclical deposition technique. In one embodiment, the tungsten barrier layer is formed on a patterned dielectric layer by alternately adsorbing the tungsten carbonyl compound and the borane compound onto a semiconductor substrate. The tungsten layers have substantially uniform dimensions and excellent adhesion to copper such as copper seed layers or direct electroplating of copper onto the tungsten layer.

    Abstract: Nitrogen containing analogs of Copper II null-diketonates which analogs are more stable source reagents for copper deposition when substantially free of solvents of excess ligands. The nitrogen containing analogs replace -O- with nullN(Rnull)nullwherein Rnull is an alkyl group having from one to four carbon atoms. Replacement of each -O- is preferred although replacement of one -O- per cyclic ring is sufficient to improve stability of the copper source reagents. The source reagent can be purified by sublimation to remove solvents and excess ligands prior to semiconductor processing.

    Abstract: A processing chamber is adapted to perform a deposition process on a substrate. The chamber includes a pedestal adapted to hold a substrate during deposition and a gas mixing and distribution assembly mounted above the pedestal. The gas mixing and distribution assembly includes a face plate, a dispersion plate mounted above the face plate, and a mixing fixture mounted above the dispersion plate. The face plate is adapted to present an emissivity invariant configuration to the pedestal. The mixing fixture includes a mixing chamber to which a process gas is flowed and an outer chamber surrounding the mixing chamber. The processing chamber further includes an enclosure and a liner installed inside the enclosure and surrounding the pedestal. The liner defines a gap between the liner and the enclosure. The gap has a minimum width adjacent an exhaust port and a maximum width at a point that is diametrically opposite the exhaust port.

    Abstract: A process of forming a via through a inter-level dielectric layer and the product. The via is formed by etching a via hole through the inter-level dielectric layer in an area overlying a conductive feature, such a lower copper metallization. Atomic layer deposition (ALD) forms a very thin refractory metal nitride barrier layer over the sidewalls and bottom of the via. Its thickness is less than 1.5 nm, and may be formed with no more than six ALD cycle. A copper seed layer is sputtered onto the barrier including the bottom portion, and copper is electrochemically filled into the hole. The barrier is thin enough to have a low electrical resistance, as may be explained by electronic quantum mechanical tunneling. Further, the crystallography and defects of the underlying copper continue across the thin barrier into the overlying copper.
