    摘要: The invention relates to an apparatus and process for the vaporization of liquid precursors and deposition of a film on a suitable substrate. Particularly contemplated is an apparatus and process for the vaporization of a metal-oxide film, such as a barium, strontium, titanium oxide (BST) film, for deposition on a silicon wafer to make integrated circuit capacitors useful in high capacity dynamic memory modules. The vaporizer comprises thermally controlled components which are adapted for easy assembly and disassembly. A main vaporizing section provides a large heated surface for flash vaporization. A high conductance blocker is disposed at a lower end of the vaporizer to provide an extended vaporization surface. Optionally, a filter may be employed to capture unvaporized precursor droplets.

    摘要: The present invention generally provides a deposition chamber for depositing materials which require vaporization, especially low volatility precursors, which are transported as a liquid to a vaporizer to be converted to vapor phase through one or more vaporizing elements and which must be transported at elevated temperatures to prevent unwanted condensation on chamber components. In one aspect, the chamber comprises a series of heated temperature controlled internal liners as vaporizing surfaces which are configured for rapid removal, cleaning and/or replacement and preferably are made of a material having a thermal coefficient of expansion close to that of the deposition material. The vaporizing surfaces “flash” sprayed liquid precursors on the surface of the vaporizing surfaces and then purify the flashed precursors before flowing further into the system. Particularly contemplated is an apparatus and process for the deposition of a metal-oxide film, such as a barium, strontium, titanium oxide (BST) film, on a silicon wafer to make integrated circuit capacitors useful in high capacity dynamic memory modules. Preferably, internal surfaces of the chamber are adjustable and maintainable at a suitable temperature above ambient, e.g., about 150° C. to about 300° C., to prevent decomposition and/or condensation of vaporized material on the chamber and related gas flow surfaces.

    摘要: A capacitor structure comprising a bottom electrode, an insulator and a top electrode, and method for manufacturing the same. The bottom and top electrodes preferably include a metal portion and a conducting oxygen-containing metal portion. In one embodiment, a layer of ruthenium is deposited to form a portion of the bottom electrode. Prior to deposition of the insulator, the ruthenium is annealed in an oxygen-containing environment. The insulator is then deposited on the oxygen-containing ruthenium layer. Formation of the top electrode includes depositing a first metal on the insulator, annealing the first metal and then depositing a second metal. The first and second metals may be ruthenium.
