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:
A structure and method for polishing a device include oscillating a carrier over an abrasive surface (the carrier bringing a polished surface of the device into contact with the abrasive surface, the oscillating allowing a portion of the polished surface to periodically oscillate off the abrasive surface), optically determining a reflective measure of a plurality of locations of the polished surface as the portion of the device oscillates off the abrasive surface and calculating depths of the locations of the polished surface based of the reflective measure.

摘要:
A trench structure and an integrated circuit comprising sub-lithographic trench structures in a substrate. In one embodiment the trench structure is created by forming sets of trenches with a lithographic mask and filling the sets of trenches with sets of step spacer blocks comprising two alternating spacer materials which are separately removable from each other. In one embodiment, the trench structures formed are one-nth the thickness of the lithographic mask's feature size. The size of the trench structures being dependent on the thickness and number of spacer material layers used to form the set of step spacer blocks. The number of spacer material layers being n/2 and the thickness of each spacer material layer being one-nth of the lithographic mask's feature size.

摘要:
A method for patterning a recording medium selectively thermally couples a recording medium and a heat source to alter a chemical composition of the recording medium. An apparatus for patterning a recording medium has a heat source for generating and directing an incident thermal wave to a recording medium so as to alter a chemical composition of the recording medium, and a controller for coordinating a mutual position of the incident thermal wave and the recording medium for inducing a direct thermal coupling between the recording medium and the heat source.
