    摘要: This invention is directed to conducting chemical reactions in reverse micelle or microemulsion systems comprising a substantially discontinuous phase including a polar fluid, typically an aqueous fluid, and a microemulsion promoter, typically a surfactant, for facilitating the formation of reverse micelles in the system. The system further includes a substantially continuous phase including a non-polar or low-polarity fluid material which is a gas under standard temperature and pressure and has a critical density, and which is generally a water-insoluble fluid in a near critical or supercritical state. Thus, the microemulsion system is maintained at a pressure and temperature such that the density of the non-polar or low-polarity fluid exceeds the critical density thereof. The method of carrying out chemical reactions generally comprises forming a first reverse micelle system including an aqueous fluid including reverse micelles in a water-insoluble fluid in the supercritical state. Then, a first reactant is introduced into the first reverse micelle system, and a chemical reaction is carried out with the first reactant to form a reaction product. In general, the first reactant can be incorporated into, and the product formed in, the reverse micelles. A second reactant can also be incorporated in the first reverse micelle system which is capable of reacting with the first reactant to form a product.

    摘要: Methods and an apparatus are disclosed for depositing tantalum metal films in next-generation solvent fluids on substrates and/or deposition surfaces useful, e.g., as metal seed layers. Deposition involves low valence oxidation state metal precursors soluble in liquid and/or compressible solvent fluids at liquid, near-critical, or supercritical conditions for the mixed precursor solutions. Metal film deposition is effected via thermal and/or photolytic activation of the metal precursors. The invention finds application in fabrication and processing of semiconductor, metal, polymer, ceramic, and like substrates or composites.
