    摘要: Methods for depositing ruthenium-containing films are provided herein. In some embodiments, a method of depositing a ruthenium-containing film on a substrate may include depositing a ruthenium-containing film on a substrate using a ruthenium-containing precursor, the deposited ruthenium-containing film having carbon incorporated therein; and exposing the deposited ruthenium-containing film to an oxygen-containing gas to remove at least some of the carbon from the deposited ruthenium-containing film. In some embodiments, the oxygen-containing gas exposed ruthenium-containing film may be annealed in a hydrogen-containing gas to remove at least some oxygen from the ruthenium-containing film. In some embodiments, the deposition, exposure, and annealing may be repeated to deposit the ruthenium-containing film to a desired thickness.

    摘要: In an on demand database system, a query engine applies a custom index for inner queries. The query engine receives a query and determines that the query has an inner query nested within the primary query. The query engine identifies that a custom index exists for a client associated with the query, and applies the custom index to filter results for the query. The custom index includes a subset of information of a table that includes accounts for multiple different clients. By using the custom index, the query engine can filter the results more efficiently that if solely using the multiple client table.
