  • Rotary signal coupling for chemical mechanical polishing endpoint detection with a westech tool
    Patent number: 5663637
    Abstract: 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.
