    摘要: Disclosed are methods for modifying the topography of HDP CVD films by modifying the composition of the reactive mixture. The methods allow for deposition profile control independent of film deposition rate. They rely on changes in the process chemistry of the HDP CVD system, rather than hardware modifications, to modify the local deposition rates on the wafer. The invention provides methods of modifying the film profile by altering the composition of the reactive gas mixture, in particular the hydrogen content. In this manner, deposition profile and wiw uniformity are decoupled from deposition rate, and can be controlled without hardware modifications.

    摘要: High density plasma chemical vapor deposition and etch back processes that can fill high aspect ratio (typically at least 5:1, for example 6:1), narrow width (typically sub 0.13 micron, for example 0.1 micron or less) gaps with significantly reduced incidence of voids or weak spots are provided. This deposition part of the process may involve the use of any suitable high density plasma chemical vapor deposition (HDP CVD) chemistry. The etch back part of the process involves an integrated multi-step (for example, two-step) procedure including an anisotropic dry etch followed by an isotropic dry etch. The all dry deposition and etch back process in a single tool increases throughput and reduces handling of wafers resulting in more efficient and higher quality gap fill operations.

    摘要: A method and apparatus for forming a green ceramic arc tube for a metal halide lamp. A feedstock material comprising ceramic and a binder is prepared and injected into an inner cavity of a mold. The inner cavity of the mold has an inner surface that corresponds to a desired outer shape of a body of the ceramic arc tube. A fluid is injected into the feedstock material to create a cavity in the feedstock material and to force the feedstock material into contact with the inner surface of the mold. The mold is then separated from the formed ceramic green arc tube.

    摘要: A binder system for forming a ceramic body, such as a translucent arc tube for a metal halide lamp, comprises a hydrocarbon, such as a paraffin wax, a copolymer, such as poly (ethylene-co-vinyl acetate), and optionally a surfactant. The binder system is mixed with a ceramic powder and heated to above the melting point of the binder. The heated mixture is formed into a compact having the general shape of the finished ceramic body and then cooled or allowed to cool. The hydrocarbon and copolymer have overlapping freezing points so that when the shaped compact cools, crystalline segments of the copolymer (such as ethylene segments) co-crystallize with the hydrocarbon, while amorphous segments (such as vinyl acetate) form bridges between the crystalline regions. As a result, the cooled compact has improved green strength over conventional binder systems.
