    摘要: Methods of controlling the step coverage and pattern loading of a layer on a substrate are provided. The dielectric layer may be a silicon nitride, silicon oxide, or silicon oxynitride layer. The method comprises depositing a dielectric layer on a substrate having at least one formed feature across a surface of the substrate and etching the dielectric layer with a plasma from oxygen or a halogen-containing gas to provide a desired profile of the dielectric layer on the at least one formed feature. The deposition of the dielectric layer and the etching of the dielectric layer may be repeated for multiple cycles to provide the desired profile of the dielectric layer.

    摘要: Compressive stress in a film of a semiconductor device may be controlled utilizing one or more techniques, employed alone or in combination. A first set of embodiments increase silicon nitride compressive stress by adding hydrogen to the deposition chemistry, and reduce defects in a device fabricated with a high compressive stress silicon nitride film formed in the presence of hydrogen gas. A silicon nitride film may comprise an initiation layer formed in the absence of a hydrogen gas flow, underlying a high stress nitride layer formed in the presence of a hydrogen gas flow. A silicon nitride film formed in accordance with an embodiment of the present invention may exhibit a compressive stress of 2.8 GPa or higher.

    摘要: A layer of silicon nitride having a thickness from 0.5 nanometers to 2.4 nanometers is deposited on a substrate. A plasma nitridation process is carried out on the layer. These steps are repeated for a plurality of additional layers of silicon nitride, until a predetermined thickness is attained. Such steps can be used to provide a multilayer silicon nitride dielectric formed on a substrate having an upper surface of dielectric material with Cu and other conductors embedded within, and a plurality of steps. The multilayer silicon nitride dielectric has a plurality of individual layers each having a thickness from 0.5 nanometers to 2.4 nanometers, and the multilayer silicon nitride dielectric conformally covers the steps of the substrate with a conformality of at least seventy percent. A multilayer silicon nitride dielectric, and a multilevel back end of line interconnect wiring structure using same, are also provided.
