    摘要： Plasma etching or resputtering of a layer of sputtered materials including opaque metal conductor materials may be controlled in a sputter reactor system. In one embodiment, resputtering of a sputter deposited layer is performed after material has been sputtered deposited and while additional material is being sputter deposited onto a substrate. A path positioned within a chamber of the system directs light or other radiation emitted by the plasma to a chamber window or other optical view-port which is protected by a shield against deposition by the conductor material. In one embodiment, the radiation path is folded to reflect plasma light around the chamber shield and through the window to a detector positioned outside the chamber window. Although deposition material may be deposited onto portions of the folded radiation path, in many applications, the deposition material will be sufficiently reflective to permit the emission spectra to be detected by a spectrometer or other suitable detector without significant signal loss. The etching or resputtering may be terminated when the detector detects that an underlying layer has been reached or when some other suitable process point has been reached.

    摘要： A processing system for workpieces such as semiconductor wafers is disclosed which incorporates multiple, isolated vacuum stages between the cassette load lock station and the main vacuum processing chambers. A vacuum gradient is applied between the cassette load lock and the main processing chambers to facilitate the use of a very high degree of vacuum in the processing chambers without lengthy pump down times. Separate robot chambers are associated with the vacuum processing chambers and the load lock(s). In addition, separate transport paths are provided between the two robot chambers to facilitate loading and unloading of workpieces. Pre-treatment and post-treatment chambers may be incorporated in the two transport paths.

    摘要： A method and apparatus is provided for depositing and planarizing a material layer on a substrate. In one embodiment, an apparatus is provided which includes a partial enclosure, a permeable disc, a diffuser plate and optionally an anode. A substrate carrier is positionable above the partial enclosure and is adapted to move a substrate into and out of contact or close proximity with the permeable disc. The partial enclosure and the substrate carrier are rotatable to provide relative motion between a substrate and the permeable disc. In another aspect, a method is provided in which a substrate is positioned in a partial enclosure having an electrolyte therein at a fist distance from a permeable disc. A current is optionally applied to the surface of the substrate and a first thickness is deposited on the substrate. Next, the substrate is positioned closer to the permeable disc and a second thickness is deposited on the substrate. During the deposition, the partial enclosure and the substrate are rotated relative one another.

    摘要： The present invention provides a carbon based etch stop, such as a diamond like amorphous carbon, having a low dielectric constant and a method of forming a dual damascene structure. The low k etch stop is preferably deposited between two dielectric layers and patterned to define the underlying interlevel contacts/vias. The second or upper dielectric layer is formed over the etch stop and patterned to define the intralevel interconnects. The entire dual damascene structure is then etched in a single selective etch process which first etches the patterned interconnects, then etches the contact/vias past the patterned etch stop. The etch stop has a low dielectric constant relative to a conventional SiN etch stop, which minimizes the capacitive coupling between adjacent interconnect lines. The dual damascene structure is then filled with a suitable conductive material such as aluminum or copper and planarized using chemical mechanical polishing.

    摘要： A magnetic field enhanced single wafer plasma etch reactor is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (walls and gas manifold) and a cooled wafer supporting cathode; and a unitary wafer exchange mechanism comprising wafer lift pins which extend through the pedestal and a wafer clamp ring. The lift pins and clamp ring are moved vertically by a one-axis lift mechanism to accept the wafer from a cooperating external robot blade, clamp the wafer to the pedestal and return the wafer to the blade. The electrode cooling combines water cooling for the body of the electrode and a thermal conductivity-enhancing gas parallel-bowed interface between the wafer and electrode for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device applies the cooling gas to the RF powered electrode without breakdown of the gas. Protective coatings/layers of materials such as quartz are provided for surfaces such as the clamp ring and gas manifold. The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher which provides uniformity, directionality and selectivity at high gas pressures, operates cleanly and incorporates in-situ self-cleaning capability.
