摘要: Methods of depositing a metal silicide on a substrate are provided herein. In some embodiments, a method of depositing a metal silicide on a substrate having a silicon containing surface includes: creating a plasma comprising a first gas in a plasma region in a chemical vapor deposition (CVD) chamber, wherein the plasma region is disposed between a lid heater and a showerhead; flowing the first gas through a plurality of first openings of the showerhead to an activation region in the CVD chamber disposed between the showerhead and the substrate; flowing a second gas comprising a metal precursor in a non-plasma state through a plurality of second openings of the showerhead to the activation region, wherein the plurality of second openings are fluidly independent from the plurality of first openings within the showerhead; mixing the first gas with the second gas to activate the second gas in the activation region; and exposing the silicon containing surface of the substrate to the activated second gas.

摘要: Methods and apparatus for processing a substrate are provided. For example, a method includes sputtering a material from a target in a PVD chamber to form a material layer on a layer comprising a feature of the substrate, the feature having an opening width defined by a first sidewall and a second sidewall, the material layer having a greater lateral thickness at the top surface of the layer than a thickness on the first sidewall or the second sidewall within the feature, depositing additional material on the layer by biasing the layer with an RF bias at a low power, etching the material layer from the layer by biasing the layer with an RF bias at a high-power, and repeatedly alternating between the low power and the high-power at a predetermined frequency.

摘要: Methods and apparatus for processing a substrate is provided herein. For example, a method for processing a substrate comprises depositing a silicide layer within a feature defined in a layer on a substrate, forming one of a metal liner layer or a metal seed layer atop the silicide layer within the feature via depositing at least one of molybdenum (Mo) or tungsten (W) using physical vapor deposition, and depositing Mo using at least one of chemical vapor deposition or atomic layer deposition atop the at least one of the metal liner layer or the metal seed layer, without vacuum break.

摘要: Embodiments disclosed herein generally relate to methods of depositing a plurality of layers. A doped copper seed layer is deposited in a plurality of feature definitions in a device structure. A first copper seed layer is deposited and then the first copper seed layer is doped to form a doped copper seed layer, or a doped copper seed layer is deposited directly. The doped copper seed layer leads to increased flowability, reducing poor step coverage, overhang, and voids in the copper layer.
