    摘要: A gate electrode connection structure formed by deposition of a tungsten nitride barrier layer and a tungsten plug, where the tungsten nitride and tungsten deposition are accomplished in situ in the same chemical vapor deposition (CVD) chamber. The tungsten nitride deposition is performed by plasma enhanced chemical vapor deposition (PECVD) using a plasma containing hydrogen, nitrogen and tungsten hexafluoride. Before deposition the wafer is pretreated with a hydrogen plasma to improve adhesion. The tungsten deposition process may be done by CVD using tungsten hexafluoride and hydrogen. A tungsten nucleation step is included in which a process gas including a tungsten hexafluoride, diborane and hydrogen are flowed into a deposition zone of a substrate processing chamber. Following the nucleation step, the diborane is shut off while the pressure level and other process parameters are maintained at conditions suitable for bulk deposition of tungsten.

    摘要: In one embodiment, a method for depositing a tungsten material on a substrate within a process chamber is provided which includes exposing the substrate to a gaseous mixture containing a tungsten precursor and a reducing gas to deposit a tungsten nucleation layer on the substrate during a tungsten deposition process. The process further includes removing reaction by-products generated during the tungsten deposition process from the process chamber, exposing the substrate to the reducing gas to react with residual tungsten precursor within the process chamber during a soak process, removing reaction by-products generated during the soak process from the process chamber, and repeating the tungsten deposition process and the soak process during a cyclic deposition process. In the examples, the reducing gas may contain diborane or silane.

    摘要: A showerhead for distributing gases in a semiconductor process chamber. In one embodiment, a showerhead comprising a perforated center portion, a mounting portion circumscribing the perforated center portion and a plurality of bosses extending from the mounting portion each having a hole disposed therethrough is provided. Another embodiment of the invention provides a showerhead that includes a mounting portion having a first side circumscribing a perforated center portion. A ring extends from the first side of the mounting portion. A plurality of mounting holes are disposed in the mounting portion radially to either side of the ring. The showerhead provides controlled thermal transfer between the showerhead and chamber lid resulting in less deposition on the showerhead.

    摘要: A method of forming a tungsten nucleation layer using a sequential deposition process. The tungsten nucleation layer is formed by reacting pulses of a tungsten-containing precursor and a reducing gas in a process chamber to deposit tungsten on the substrate. Thereafter, reaction by-products generated from the tungsten deposition are removed from the process chamber. After the reaction by-products are removed from the process chamber, a flow of the reducing gas is provided to the process chamber to react with residual tungsten-containing precursor remaining therein. Such a deposition process forms tungsten nucleation layers having good step coverage. The sequential deposition process of reacting pulses of the tungsten-containing precursor and the reducing gas, removing reaction by-products, and than providing a flow of the reducing gas to the process chamber may be repeated until a desired thickness for the tungsten nucleation layer is formed.
