    摘要: The present disclosure provides an apparatus for fabricating a semiconductor device. The apparatus includes a polishing head that is operable to perform a polishing process to a wafer. The apparatus includes a retaining ring that is rotatably coupled to the polishing head. The retaining ring is operable to secure the wafer to be polished. The apparatus includes a soft material component located within the retaining ring. The soft material component is softer than silicon. The soft material component is operable to grind a bevel region of the wafer during the polishing process. The apparatus includes a spray nozzle that is rotatably coupled to the polishing head. The spray nozzle is operable to dispense a cleaning solution to the bevel region of the wafer during the polishing process.

    摘要: Methods and apparatus for detecting errors in real time in CMP processing. A method includes disposing a semiconductor wafer onto a wafer carrier in a tool for chemical mechanical polishing (“CMP”); positioning the wafer carrier so that a surface of the semiconductor wafer contacts a polishing pad mounted on a rotating platen; dispensing an abrasive slurry onto the rotating polishing pad while maintaining the surface of the semiconductor wafer in contact with the polishing pad to perform a CMP process on the semiconductor wafer; in real time, receiving signals from the CMP tool into a signal analyzer, the signals corresponding to vibration, acoustics, temperature, or pressure; and comparing the received signals from the CMP tool to expected received signals for normal processing by the CMP tool; outputting a result of the comparing. A CMP tool apparatus is disclosed.
