摘要： Embodiments of the invention provide methods for forming conductive materials within contact features on a substrate by depositing a seed layer within a feature and subsequently filling the feature with a copper-containing material during an electroless deposition process. In one example, a copper electroless deposition solution contains levelers to form convexed or concaved copper surfaces. In another example, a seed layer is selectively deposited on the bottom surface of the aperture while leaving the sidewalls substantially free of the seed material during a collimated PVD process. In another example, the seed layer is conformably deposited by a PVD process and subsequently, a portion of the seed layer and the underlayer are plasma etched to expose an underlying contact surface. In another example, a ruthenium seed layer is formed on an exposed contact surface by an ALD process utilizing the chemical precursor ruthenium tetroxide.

摘要： A semiconductor processing chamber is cleaned by introducing a cleaning gas into a processing chamber, striking a plasma in a remote plasma source that is in communication with the processing chamber, measuring the impedance of the plasma, vaporizing a ruthenium containing deposit on a surface of the processing chamber to form a ruthenium containing gas mixture, and flowing the gas mixture through an analyzer and into an exhaust collection assembly. The measurement of the impedance of the plasma in combination with the ruthenium concentration provides an accurate indication of chamber cleanliness.

摘要： Embodiments of the invention provide a method for depositing ruthenium materials on a substrate by various vapor deposition processes, such as atomic layer deposition (ALD) and plasma-enhanced ALD (PE-ALD). In one aspect, the process has little or no initiation delay and maintains a fast deposition rate while forming a ruthenium material. The ruthenium material may be deposited with good step coverage, strong adhesion, and contains a low carbon concentration for high electrical conductivity. The method for depositing the ruthenium material on a substrate generally includes sequentially exposing the substrate to a pyrrolyl ruthenium precursor and a reagent during the ALD process. The pyrrolyl ruthenium precursor contains ruthenium and at least one pyrrolyl ligand. In some examples, the reagent may contain a plasma of ammonia, nitrogen, or hydrogen during a PE-ALD process. In other examples, a reducing gas may be used during a thermal ALD process.
