摘要:
An antimony/Lewis base adduct of the formula SbR.sub.3.L, wherein each R is independently selected from C.sub.1 -C.sub.8 alkyl, C.sub.1 -C.sub.8 perfluoroalkyl, C.sub.1 -C.sub.8 haloalkyl, C.sub.6 -C.sub.10 aryl, C.sub.6 -C.sub.10 perfluoroaryl, C.sub.6 -C.sub.10 haloaryl, C.sub.6 -C.sub.10 cycloalkyl, substituted C.sub.6 -C.sub.10 aryl and halo; and L is a Lewis base ligand coordinating with SbR.sub.3. The adducts of the invention are useful as metal source compositions for chemical vapor deposition, assisted chemical vapor deposition (e.g., laser-assisted chemical vapor deposition, light-assisted chemical vapor deposition, plasma-assisted chemical vapor deposition and ion-assisted chemical vapor deposition), ion implantation, molecular beam epitaxy, and rapid thermal processing, to form antimony or antimony-containing films.
摘要:
A method of forming a thin film of BaSrTiO.sub.3 on a substrate in a chemical vapor deposition zone, with transport of a metal precursor composition for the metal-containing film to the chemical vapor deposition zone via a liquid delivery apparatus including a vaporizer. A liquid precursor material is supplied to the liquid delivery apparatus for vaporization thereof to yield the vapor-phase metal precursor composition. The vapor-phase metal precursor composition is flowed to the chemical vapor deposition zone for deposition of metal on the substrate to form the metal-containing film. The liquid precursor material includes a metalorganic polyamine complex, the use of which permits the achievement of sustained operation of the liquid delivery chemical vapor deposition process between maintenance events, due to the low decomposition levels achieved in the vaporization of the polyamine-complexed precursor.
摘要:
A metal hydride derivative wherein at least one hydrogen atom is replaced by deuterium (.sup.2.sub.1 H) or tritium (.sup.3.sub.1 H) isotope. The metal constituent of such metal hydride may be a Group III, IV or V metal or a transition metal, e.g., antimony, aluminum, gallium, tin, or germanium. The isotopically stabilized metal hydride derivatives of the invention are useful as metal source compositions for chemical vapor deposition, assisted chemical vapor deposition (e.g., laser-assisted chemical vapor deposition, light-assisted chemical vapor deposition, plasma-assisted chemical vapor deposition and ion-assisted chemical vapor deposition), ion implantation, molecular beam epitaxy, and rapid thermal processing.
摘要:
A solvent composition useful for liquid delivery chemical vapor deposition of organometallic precursors such as .beta.-diketonate metal precursors. The solvent composition comprises a mixture of solvent species A, B and C in the proportion A:B:C wherein A is from about 3 to about 7 parts by volume, B is from about 2 to about 6 parts by volume, and C is from 0 to about 3 parts by volume, wherein A is a C.sub.6 -C.sub.8 alkane, B is a C.sub.8 -C.sub.12 alkane, and C is a glyme-based solvent (glyme, diglyme, tetraglyme, etc.) or a polyamine. The particular solvent composition including octane, decane and polyamine in an approximate 5:4:1 weight ratio is particularly usefully employed in the formation of SrBi.sub.2 Ta.sub.2 O.sub.9 films.

A metal hydride derivative wherein at least one hydrogen atom is replaced by deuterium (21H) or tritium (31H) isotope. The metal constituent of such metal hydride may, be a Group III, IV or V metal or a transition metal, e.g., antimony, aluminum, gallium, tin, or germanium. The isotopically stabilized metal hydride derivatives of the invention are useful as metal source compositions for chemical vapor deposition, assisted chemical vapor deposition (e.g., laser-assisted chemical vapor deposition, light-assisted chemical vapor deposition, plasma-assisted chemical vapor deposition and ion-assisted chemical vapor deposition), ion implantation, molecular beam epitaxy, and rapid thermal processing.
摘要:
A liquid reagent delivery and vaporization system, including a housing defining a flow passage for flow of a process fluid therethrough. A vaporizer element is positioned within the housing and includes a heated vaporization surface. Liquid reagent is selectively delivered to the heated vaporization surface, to vaporize the liquid reagent and form reagent vapor for flow through the flow passage of the housing, e.g., to a chemical vapor deposition reactor for deposition of a film on a substrate. A thermal damping fluid source is arranged to selectively deliver a thermal damping fluid into the flow passage to maintain a predetermined thermal condition therein. For example, the system may be arranged to selectively terminate delivery of liquid reagent to the vaporization surface and to contemporaneously selectively initiate delivery of the thermal damping fluid into the flow passage to maintain a thermal condition thermally matches the vaporization conditions when the liquid reagent is vaporized. The use of a thermal damping fluid prevents the occurrence of undesired thermal gradients in the system when the system is cyclically operated to vaporize reagent liquid.
摘要:
A hydrogen sensor for the detection of hydrogen, e.g., in an environment susceptible to the incursion or generation of hydrogen. The sensor includes a rare earth metal thin film arranged for exposure to the environment and exhibiting a detectable change of physical property, e.g., optical transmissivity, electrical resistivity, magneto-resistance, and/or photoconductivity, when the rare earth metal thin film is contacted with hydrogen gas. The sensor may include an output assembly for converting the physical property change to a perceivable output. The rare earth metal thin film may correspondingly be used for signal processing applications, in which the rare earth metal thin film is contacted with hydrogen gas, and a predetermined voltage signal is selectively imposed across the rare earth metal thin film, to selectively electrically switch the film between mirror and window states, with a response being generated according to which of the mirror and window states is present.
