    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: Methods of forming silicon oxide layers are described. The methods include concurrently combining plasma-excited (radical) steam with an unexcited silicon precursor. Nitrogen may be supplied through the plasma-excited route (e.g. by adding ammonia to the steam) and/or by choosing a nitrogen-containing unexcited silicon precursor. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain little or no nitrogen. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.

    摘要: Methods, materials, and systems are described for forming conformal dielectric layers containing silicon and nitrogen (e.g., a silicon-nitrogen-hydrogen (Si—N—H) film) from a carbon-free silicon-and-nitrogen precursor and radical-nitrogen precursor. The carbon-free silicon-and-nitrogen precursor is predominantly excited by contact with the radical-nitrogen precursor. Because the silicon-and-nitrogen film is formed without carbon, the conversion of the film into hardened silicon oxide is done with less pore formation and less volume shrinkage. The deposited silicon-and-nitrogen-containing film may be wholly or partially converted to silicon oxide which allows the optical properties of the conformal dielectric layer to be selectable. The deposition of a thin silicon-and-nitrogen-containing film may be performed at low temperature to form a liner layer in a substrate trench. The low temperature liner layer has been found to improve the wetting properties and allows flowable films to more completely fill the trench.

    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.
