摘要： Rotary signal coupling in in-situ monitoring of a chemical-mechanical polishing process. A sensor fixed to a rotatable wafer carrier for creating a signal responsive to the chemical mechanical polishing process is coupled to a bottom half of a rotary transformer fixed to a rotating portion of the polisher. A top half of the rotary transformer, coupled to the bottom half of the rotary transformer, is fixed to a stationary portion of the polisher. The signal from the sensor is thus coupled through the rotary transformer to a process monitor.

摘要： An improved method of in-situ conditioning of a polishing pad for use with a stationary pad conditioner during chemical mechanical polishing is described. A polishing table having a polishing pad on its surface is rotated in a first direction during polishing of a semiconductor wafer. A polishing pad conditioner is adjustably attached to the rotating polishing table such that the conditioner is stationary in relation to the rotating polishing table. The conditioner has a roughened surface which is in contact with the polishing pad providing in-situ conditioning during polishing of a semiconductor wafer. After polishing of the semiconductor wafer, the polishing table is rotated in a second direction while the conditioner is still in contact with polishing pad. Rotating the polishing pad in a second direction dislodges the polishing debris clogging the roughened surface of the conditioner and redistributes CMP slurry. The roughened surface of the pad conditioner is refreshed allowing more effective conditioning of the polishing pad. Pad life is prolonged, polishing is stabilized, and the polish cycle time is reduced.

摘要： A recirculation mechanism is used to force slurry toward the center of a platen used for chemical-mechanical polishing. The recirulator captures the slurry that would otherwise be flung from a rotating platen because of centrifugal force. The captured slurry is forced upwardly away from the surface of the platen and toward the center of the platen to recycle the slurry.

摘要： A device and method for providing precision alignment and support for an optical film measurement probe in the wafer rinse tank of a CMP polish tool. The device includes of a probe carrier, and spring loaded support guides attached to a support ring that supports and locates the mechanism in the rinse tank of the CMP tool. The probe carrier has multiple beveled bearing pads (three or more) that contact the rim of the rotating wafer chuck. Pressure from the chuck against these pads forces the probe carrier to maintain a fixed distance and orientation relative to the wafer while allowing the smooth rotation and motion of the wafer and chuck. Further, an integrated the wafer spray nozzles can be attached to the probe carrier that is located so as to minimize interference between wafer spraying and the probe carrier.

摘要： A system and method that integrates film thickness measurements with a chemical-mechanical polishing (CMP) spin-dry tool. By doing so, each wafer can be measured as it comes out of the previous CMP process. Thickness measurement feedback is provided, which controls processing of the wafer and also monitor operational status of a CMP polishing unit prior to completion of the wafer being polished, resulting in significant cost and cycle time reduction through the elimination of tool infrastructure and wafer handling by assuring proper tolerances of the CMP polishing unit are maintained.

摘要： An apparatus for polishing a semiconductor wafer is provided which includes a wafer carrier having on its lower surface a non-uniform surface structure means to vary the force against a wafer during a polishing operation so that the polishing is enhanced and imparts a planar surface across the polished wafer. Preferred non-uniform surface structure means include use of a wafer carrier having on its lower surface a backing film having a first central portion having a predetermined compressibility and a second peripheral portion having a different compressibility than the first portion. Another non-uniform surface structure means to vary the force against the wafer comprises a wafer carrier having on its lower surface a raised circumferential region around the periphery of the carrier.
