    Abstract: A photographic mask is provided in the present disclosure. The photographic mask includes a silicon-on-insulator (SOI) base and a stepped opening formed in the SOI base. The SOI base includes a silicon substrate, a median layer and a silicon layer, the median layer is arranged between the insulator substrate and the insulator layer. The stepped opening includes a first opening portion and a second opening portion, the first opening portion penetrates through the silicon layer and has a first opening area; the second opening portion at least penetrates through the silicon substrate and is aligned with the first opening portion. The second opening portion has a second opening area greater than the first opening area of the first opening portion. The present disclosure further provides a method for making a photographic mask.

    Abstract: A method of etching silicon-and-carbon-containing material is described and includes a SiConi™ etch in combination with a flow of reactive oxygen. The reactive oxygen may be introduced before the SiConi™ etch reducing the carbon content in the near surface region and allowing the SiConi™ etch to proceed more rapidly. Alternatively, reactive oxygen may be introduced during the SiConi™ etch further improving the effective etch rate.

    Abstract: Methods are described for forming and curing a flowable silicon-carbon-and-nitrogen-containing layer on a semiconductor substrate. The silicon and carbon constituents may come from a silicon and carbon containing precursor while the nitrogen may come from a nitrogen-containing precursor that has been activated to speed the reaction of the nitrogen with the silicon-and-carbon-containing precursor at lower deposition chamber temperatures. The initially-flowable silicon-carbon-and-nitrogen-containing layer is treated to remove components which enabled the flowability, but are no longer needed after deposition. Removal of the components increases etch resistance in order to allow the gapfill silicon-carbon-and-nitrogen-containing layer to remain intact during subsequent processing. The treatments have been found to decrease the evolution of properties of the film upon exposure to atmosphere.

    Abstract: Methods of forming a dielectric layer are described. The methods include the steps of mixing a silicon-containing precursor with a plasma effluent, and depositing a silicon-and-nitrogen-containing layer on a substrate. The silicon-and-nitrogen-containing layer is converted to a silicon-and-oxygen-containing layer by curing in an ozone-containing atmosphere in the same substrate processing region used for depositing the silicon-and-nitrogen-containing layer. Another silicon-and-nitrogen-containing layer may be deposited on the silicon-and-oxygen-containing layer and the stack of layers may again be cured in ozone all without removing the substrate from the substrate processing region. After an integral multiple of dep-cure cycles, the conversion of the stack of silicon-and-oxygen-containing layers may be annealed at a higher temperature in an oxygen-containing environment.
