    摘要： A trench-fill material is deposited to fill a trench in a substrate disposed in a process chamber. An inert gas is introduced into the process chamber and a plasma is formed to heat the substrate to a preset temperature, which is typically the temperature at which deposition of the trench-fill material is to take place. The plasma is terminated upon reaching the preset temperature for the substrate. A process gas is then flowed into the process chamber without plasma excitation until the process gas flow and distribution achieve a generally steady state in the process chamber. A plasma is then formed to deposit the trench-fill material on the surface of the substrate and fill the trench. By establishing generally steady state conditions in the chamber prior to deposition, transient effects are reduced and more uniform deposition of the trench-fill material is obtained. The step of forming the plasma typically includes coupling source plasma energy into the process chamber at a total power density of at least about 15 Watts/cm2. The energy is inductively coupled into the process chamber by coupling a top coil with a top portion of the process chamber above the surface of the substrate and coupling a side coil with a side portion of the process chamber generally surrounding the side edge of the substrate. The top coil is powered at a top RF power level to produce a top power density and the side coil is-powered at a side RF power level to produce a side power density. The total RF power density is equal to the sum of the top and side power densities. The top power density and the side power density desirably have a ratio of at least about 1.5. The high source plasma power density generates a high ion density plasma and produces a more directional deposition, and a higher top power density relative to the side power density produces a more uniform plasma over the substrate, resulting in improved trench fill, particularly for aggressive trenches having aspect ratios of about 3:1 to 4:1. The process gas typically includes silicon, oxygen, and an inert component having a concentration of less than about 40%, by volume. In specific embodiments, the concentration of the inert component is equal to about 0%.

    摘要： A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after depositing a layer of material over a substrate disposed in the chamber. In one embodiment the process comprises transferring the substrate out of the chamber; flowing a first gas into the substrate processing chamber and forming a plasma within the chamber from the first gas in order to heat the chamber; and thereafter, extinguishing the plasma, flowing an etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to etch the unwanted deposition build-up.

    摘要： A method for depositing a conformal dielectric layer employing a dep-etch technique features selectively decreasing the deposition gas present in a process chamber where a substrate to be covered by the conformal dielectric layer is disposed. By selectively decreasing the deposition gas present in the process chamber, the concentration of a sputtering gas, from which a plasma is formed, in the process chamber is increased. It is preferred that the flow of deposition gases be periodically terminated so as to provide a sputtering gas concentration approaching 100%. In this fashion, the etch rate of a conformal dielectric layer having adequate gap-filling characteristics may be greatly increased, while allowing an increase in the deposition rate of the same.

    摘要： Methods are provided for identifying root causes of particle issues and for developing particle-robust process recipes in plasma deposition processes. The presence of in situ particles within the substrate processing system is detected over a period of time that spans multiple distinct processing steps in the recipe. The time dependence of in situ particle levels is determined from these results. Then, the processing steps are correlated with the time dependence to identify relative particle levels with the processing steps. This information provides a direct indication of which steps result in the production of particle contaminants so that those steps may be targeted for modification in the development of particle recipes.

    摘要： A method and apparatus for depositing a conformal dielectric layer employing a dep-etch technique features selectively reducing the flow of deposition gases into a process chamber where a substrate having a stepped surface to be covered by the conformal dielectric layer is disposed. By selectively reducing the flow of deposition gases into the process chamber, the concentration of a sputtering gas, from which a plasma is formed, in the process chamber is increased without increasing the pressure therein. It is preferred that the flow of deposition gases be periodically terminated so as to provide a sputtering gas concentration approaching 100%. In this fashion, the etch rate of a conformal dielectric layer having adequate gap-filling characteristics may be greatly increased, while allowing an increase in the deposition rate of the same.

    摘要： A method and system for forming a layer on a substrate in a process chamber are provided. Deposition gases are provided to the process chamber and permitted to mix in the desired relative concentrations prior to the deposition step, resulting in improved composition uniformity of the layer. This may be accomplished by generating a heating plasma from a first gaseous mixture. The plasma is then terminated and a second gaseous mixture is provided to the process chamber such that the second gaseous mixture is substantially uniformly mixed. A second plasma is then generated from the second gaseous mixture to deposit the layer on the substrate.

    摘要： A layer of reduced stress is formed on a substrate using an HDP-CVD system by delaying or interrupting the application of capacitively coupled RF energy. The layer is formed by introducing a process gas into the HDP system chamber and forming a plasma from the process gas by the application of RF power to an inductive coil. After a selected period, a second layer of the film is deposited by maintaining the inductively-coupled plasma and biasing the plasma toward the substrate to enhance the sputtering effect of the plasma. In a preferred embodiment, the deposited film is a silicon oxide film, and biasing is performed by application of capacitively coupled RF power from RF generators to a ceiling plate electrode and wafer support electrode.
