摘要： A method and assembly for recovering a metal from by-products produced from etching a metal (e.g., platinum, iridium, aluminum, etc.) in a plasma processing chamber. The method includes recovering from the plasma processing chamber a deposit of the by-products containing the metal. The deposit is dissolved in an acid, and the metal is recovered from the acid by inserting a working electrode, a reference electrode, and a counter electrode into the acid and applying a difference in potential between the working and reference electrodes to cause current to flow through the working and counter electrodes and the metal to be removed from the liquid and deposit on the working electrode. The metal is removed from the working electrode to recover the metal. The assembly for recovering the metal from the by-products includes a potentiostat for effecting a difference in potential between the working and reference electrodes and causing current to flow through the working and counter electrodes in response to the difference in potential between the working and reference electrodes.

摘要： A method of patterning a layer of dielectric material having a thickness greater than 1,000 Å, and typically a thickness greater than 5,000 Å. The method is particularly useful for forming a high aspect ratio via or a high aspect ratio contact including self-aligned contact structures, where the aspect ratio is typically greater than 3 and the feature size of the contact is about 0.25 &mgr;m or less. In particular, an organic, polymeric-based masking material is used in a plasma etch process for transferring a desired pattern through an underlying layer of dielectric material. The combination of masking material and plasma source gas must provide the necessary high selectivity toward etching of the underlying layer of dielectric material. The selectivity is preferably greater than 3:1, where the etch rate of the dielectric material is at least 3 times greater than the etch rate of the organic, polymeric-based masking material. The dielectric material may be inorganic, for example, silicon oxide; doped silicon oxide; carbon-containing silicon oxide; SOG; BPSG; and similar materials. The dielectric material may be also be organic, where a high temperature organic-based masking material is used for transferring a desired pattern, and the underlying dielectric material is of a chemical and structural composition which is sufficiently different from the masking material that the required selectivity is provided. In any case, the organic, polymeric-based masking material is easily removed from the substrate etch process after completion of etch without damage to underlying device structures.

摘要： An RF plasma etch reactor having an etch chamber with electrically conductive walls and a protective layer forming the portion of the walls facing the interior of the chamber. The protective layer prevents sputtering of material from the chamber walls by a plasma formed within the chamber. The etch reactor also has an inductive coil antenna disposed within the etch chamber which is used to generate the plasma by inductive coupling. Like the chamber walls, the inductive coil antenna is constructed to prevent sputtering of the material making up the antenna by the plasma. The coil antenna can take on any configuration (e.g. location, shape, orientation) that is necessary to achieve a desired power deposition pattern within the chamber. Examples of potential coil antenna configurations for achieving the desired power deposition pattern include constructing the coil antenna with a unitary or a segmented structure. The segmented structure involves the use of at least two coil segments wherein each segment is electrically isolated from the other segments and connected to a separate RF power signal. The unitary coil antenna or each of the coil segments can have a planar shape, a cylindrical shape, a truncated conical shape, a dome shape, or any combination thereof. The conductive walls are electrically grounded to serve as an electrical ground (i.e. anode) for a workpiece-supporting pedestal which is connected to a source of RF power to create a bias voltage at the surface of the workpiece.
