    Abstract: A method and apparatus for removing conductive material from a microelectronic substrate. In one embodiment, a support member supports a microelectronic substrate relative to a material removal medium, which can include first and second electrodes and a polishing pad. One or more electrolytes are disposed between the electrodes and the microelectronic substrate to electrically link the electrodes to the microelectronic substrate. The electrodes are then coupled to a source of varying current that electrically removes the conductive material from the substrate. The microelectronic substrate and/or the electrodes can be moved relative to each other to position the electrodes relative to a selected portion of the microelectronic substrate, and/or to polish the microelectronic substrate. The material removal medium can remove gas formed during the process from the microelectronic substrate and/or the electrodes. The medium can also have different first and second electrical characteristics to provide different levels of electrical coupling to different regions of the microelectronic substrate.

    Abstract: Planarizing machines and methods for accurately planarizing microelectronic workpieces. Several embodiments of the planarizing machines produce a planar surface at a desired endpoint in the microelectronic workpieces by (a) quickly reducing variances on the surface of the workpiece using a planarizing medium that removes topographical features but has a low polishing rate on planar surfaces; and (b) subsequently planarizing the wafer on a planarizing medium that has a higher polishing rate on planar surfaces than the first polishing medium.

    Abstract: CMP methods reduce a cause of differences between an edge profile of a chemical mechanical polished edge of a wafer and a center profile of a chemical mechanical polished central portion of the wafer within the edge. The wafer is mounted on a carrier surface of a wafer carrier so that a wafer axis of rotation is gimballed for universal movement relative to a spindle axis of rotation of a wafer spindle. An operation using a retainer ring limits wafer movement on the carrier surface perpendicular to the wafer axis. Another operation limits a direction of permitted movement between the wafer carrier and the retainer ring to only movement parallel to the wafer axis, so that a wafer plane and a retainer ing may be co-planar.

    Abstract: A slurry distribution system for distributing slurry to a polishing machine that polishes a semiconductor wafer is disclosed. The slurry distribution system includes a storage tank for storing the slurry, a mixing device for mixing the slurry in the storage tank, a distribution loop with an inlet and outlet in fluid communication with the storage tank, a valve in fluid communication with the distribution loop for dispensing the slurry to the polishing machine, and a pump for circulating the slurry from the storage tank through the distribution loop and into the storage tank regardless of whether the slurry is dispensed to the polishing machine. In this manner, the slurry is agitated and efficiently used during polishing and during intervals between polishing.

    Abstract: A spiral pattern abrading tool applies a cross hatch pattern to a flat surface in a single pass rather than two passes as has been used in the past. The abrading tool comprising an abrading holder having a plurality of abrasion members flexibly mounted from pre-determined points on the holder. The points being arranged in a pattern with a series of arcs extending out from the center of the holder, the points spaced apart at pre-determined distances along the arcs such that rotation of the holder in either direction provides a spiral pattern of abrasion members. To apply the cross hatch pattern, the flat surface is rotated and the abrading tool rotated so that a spiral pattern is applied to the flat surface.

    Abstract: A number of blocks are reciprocably supported in a polishing apparatus in accordance with this invention, entirely independent of each other so that lifting motion of one block is not transferred to an adjacent block, thus providing flexibility to follow the global curvature of the wafer. The polishing apparatus uses a block of a very hard design to ensure minimal deflection of the block into the microstructure of the wafer. Each block removes a portion of the wafer using relative motion between the block and the wafer. Each block is supported by at least three regions of the wafer during the relative motion, wherein each of the regions has the slowest rate of material removal in a die enclosing that region. In one embodiment, the smallest dimension of a block is approximately three times the size of the side of a die. The three point support and hard design of the blocks ensure local polishing removal uniformity while the independent support of the blocks ensures global uniformity, thus achieving an advantage over the conventional polishing process and apparatus.
