    摘要: Methods of filling a gap on a substrate with silicon oxide are described. The methods may include the steps of introducing an organo-silicon precursor and an oxygen precursor to a deposition chamber, reacting the precursors to form a first silicon oxide layer in the gap on the substrate, and etching the first silicon oxide layer to reduce the carbon content in the layer. The methods may also include forming a second silicon oxide layer on the first layer, and etching the second layer to reduce the carbon content in the second layer. The silicon oxide layers are annealed after the gap is filled.

    摘要: Methods of forming a dielectric layer where the tensile stress of the layer is increased by a plasma treatment at an elevated position are described. In one embodiment, oxide and nitride layers are deposited on a substrate and patterned to form an opening. A trench is etched into the substrate. The substrate is transferred into a chamber suitable for dielectric deposition. A dielectric layer is deposited over the substrate, filling the trench and covering mesa regions adjacent to the trench. The substrate is raised to an elevated position above the substrate support and exposed to a plasma which increases the tensile stress of the substrate. The substrate is removed from the dielectric deposition chamber, and portions of the dielectric layer are removed so that the dielectric layer is even with the topmost portion of the nitride layer. The nitride and pad oxide layers are removed to form the STI structure.

    摘要: A plasma treatment process for increasing the tensile stress of a silicon wafer is described. Following deposition of a dielectric layer on a substrate, the substrate is lifted to an elevated position above the substrate receiving surface and exposed to a plasma treatment process which treats both the top and bottom surface of the wafer and increases the tensile stress of the deposited layer. Another embodiment of the invention involves biasing of the substrate prior to plasma treatment to bombard the wafer with plasma ions and raise the temperature of the substrate. In another embodiment of the invention, a two-step plasma treatment process can be used where the substrate is first exposed to a plasma at a processing position directly after deposition, and then raised to an elevated position where both the top and bottom of the wafer are exposed to the plasma.

    摘要: A method of forming a silicon oxide layer is described. The method increases the oxygen content of a dielectric layer by curing the layer in a two-step ozone cure. The first step involves exposing the dielectric layer to ozone while the second step involves exposing the dielectric layer to ozone excited by a local plasma. This sequence can reduce or eliminate the need for a subsequent anneal following the cure step. The two-step ozone cures may be applied to silicon-and-nitrogen-containing film to convert the films to silicon oxide.

    摘要: A method of forming a dielectric layer is described. The method first deposits a silicon-nitrogen-and-hydrogen-containing (polysilazane) layer by radical-component chemical vapor deposition (CVD). The silicon-nitrogen-and-hydrogen-containing layer is formed by combining a radical precursor (excited in a remote plasma) with an unexcited carbon-free silicon precursor. A silicon oxide capping layer may be formed from a portion of the carbon-free silicon-nitrogen-and-hydrogen-containing layer to avoid time-evolution of underlying layer properties prior to conversion into silicon oxide. Alternatively, the silicon oxide capping layer is formed over the silicon-nitrogen-and-hydrogen-containing layer. Either method of formation involves the formation of a local plasma within the substrate processing region.
