Abstract: An absorbing ether-like compound including a siliconethoxy, silicondiethoxy, or silicontriethoxy species attached to a naphthalene or anthracene chromophore via an oxygen linkage is used as an organic light-absorbing compound. The absorbing ether-like compound is incorporated into spin-on glass materials to provide anti-reflective coating materials for deep ultraviolet photolithography. A method of synthesizing the light-absorbing ether compounds is based on the reaction of an alcohol-substituted chromophore with an acetoxysilicon compound in the presence of alcohol. A method of making absorbing spin-on-glass materials including the absorbing ether-like compounds is also provided.

Abstract: A process for treating a silica film on a substrate, which includes reacting a suitable silica film with an effective amount of a surface modification agent, wherein the silica film is present on a substrate. The reaction is conducted under suitable conditions and for a period of time sufficient for the surface modification agent to form a hydrophobic coating on the film. The surface modification agent includes at least one type of oligomer or polymer reactive with silanols on the silica film. Dielectric films and integrated circuits including such films are also disclosed.

Abstract: Polyorganosilicon dielectric coatings are prepared by subjecting specified polycarbosilanes to thermal or high energy treatments to generate cross-linked polyorganosilicon coatings having low k dielectric properties. The thermal process includes multi-step sequentially increasing temperature heating steps. The instantly prepared polyorganosilicon polymers can be employed as dielectric interconnect materials and film coatings for conductor wiring in semiconductor devices. These polyorganosilicon film coatings have the additional characteristics of relative thermal stability and excellent adhesion to substrate surfaces.

Abstract: Nanoporous low dielectric constant materials are fabricated from a first reagent and a second reagent. The reagents are mixed to give a reagent mixture and a polymeric structure is formed from the reagent mixture. Nanosized voids are created by removing at least in part the second reagent from the polymeric structure by a method other than thermolysis, and other than evaporation.

Abstract: A process for treating silica dielectric film on a substrate, which includes reacting a suitable hydrophilic silica film with an effective amount of a multifunctional surface modification agent. The film is present on a substrate and optionally has a pore structure with hydrophilic pore surfaces, and the reaction is conducted for a period of time sufficient for said surface modification agent to penetrate said pore structure and produce a treated silica film having a dielectric constant of about 3 or less, wherein the surface modification agent is hydrophobic and suitable for silylating or capping silanol moieties on such hydrophilic surfaces. Dielectric films and integrated circuits including such films are also disclosed.

Abstract: A process for forming a nanoporous dielectric silica coating on a surface of a substrate. The process includes spin-depositing alkoxysilane composition onto a surface of a substrate; spin depositing a surface hydrophobizing agent or a solvent onto an edge portion of the substrate to thereby remove the alkoxysilane composition from that area; and then curing the alkoxysilane composition to form a nanoporous dielectric silica coating. In another embodiment, an alkoxysilane composition layer is deposited onto a surface of a substrate. Then a solvent for the alkoxysilane substantially removes a portion of the alkoxysilane layer on the edge portion of the surface. This results in a transfer or cascading of a quantity of the alkoxysilane from a region adjacent to the edge portion to form a relatively thinner layer of the alkoxysilane onto the edge portion of the substrate surface. Then the relatively thinner alkoxysilane layer is removed prior to curing the alkoxysilane.

Abstract: A process for forming a nanoporous dielectric coating on a substrate. The process includes either (i) combining a stream of an alkoxysilane composition with a stream of a base containing catalyst composition to form a combined composition stream; immediately depositing the combined composition stream onto a surface of a substrate and exposing the combined composition to water (in either order or simultaneously); and curing the combined composition; or (ii) combining a stream of an alkoxysilane composition with a stream of water to form a combined composition stream; immediately depositing the combined composition stream onto a surface of a substrate; and curing the combined composition.

Abstract: An invention is disclosed which comprises gelling agents which (1) contain both siloxane groups and hydrogen-bonding groups to thicken compositions containing silicone fluids (volatile and/or non-volatile silicone fluids); (2) are non-flowable solids at room temperature; and (3) dissolve in a fluid which contains silicone at a temperature of 25-250 degrees C to form a translucent or clear solution at a temperature in this range. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

Abstract: A base composition and corresponding cosmetic composition are disclosed which can be formed as solids (for example, gels or sticks) and which comprise a solvent which includes a silicone fluid (for example, a silicone oil such as cyclomethicone) and a thickening agent formed from a wax and a polyamide gellant wherein at least one of the wax and polyamide includes silicon-containing moieties (for example, siloxane groups to have a siloxane diamide wax to enhance compatibility of the silicone fluid in the composition. A cosmetically active material, such as a deodorant or antiperspirant active material, is included in the composition to form a solid cosmetic product (antiperspirant or deodorant product), which can be a clear product. Compositions of the present invention can be made with increased amounts of silicone fluid and with improved aesthetics such as decreased tack.
