    摘要: A metal silicide layer is formed on silicon-containing features of a substrate in a chamber. A metal film is sputter deposited on the substrate and a portion of the sputter deposited metal film is silicided. In the process, sputtering gas is energized by applying an electrical bias potential across the metal sputtering target and the substrate support to sputter deposit metal from a target onto the substrate. At least a portion of the deposited sputtered metal is silicided by heating the substrate to a silicidation temperature exceeding about 200° C. to form a combined sputtered metal and metal silicide layer on the substrate. The remaining sputtered metal can be silicided by maintaining the substrate at the silicidation temperature to form the metal silicide layer.

    摘要: Methods and apparatus to improve target life and deposition uniformity in PVD chambers are provided herein. In some embodiments, a magnetron assembly includes a shunt plate having a central axis, the shunt plate rotatable about the central axis, a first open loop magnetic pole arc coupled to the shunt plate at a first radius from the central axis, and a second open loop magnetic pole arc coupled the shunt plate at a first distance from the first open loop magnetic pole arc, wherein at least one of the first radius varies along the first open loop magnetic pole arc or the first distance varies along the second open loop magnetic pole arc. In some embodiments, a first polarity of the first open loop magnetic pole arc opposes a second polarity of the second open loop magnetic pole arc.
