FPA-5550iZ2 provides high productivity and overlay accuracy.
  • FPA-5550iZ2 steppers reduce wafer processing time by optimizing the alignment, exposure and wafer transfer sequences.

  • FPA-5550iZ2 steppers shorten lot replacement time and speed up measurement and calibration processing to enable high productivity.

  • FPA-5550iZ2 steppers are equipped with a Shot Shape Compensator (SSC Unit) to enable shot shape correction of vertical and horizontal magnification differences and skew (shot distortion in diagonal orientation) within each exposure field.

  • Shot Shape Compensator employs original Canon technology in the projection optical system that allows improved matching to underlying layers and improved overlay accuracy.

FPA-5550iZ2 steppers provide a variety of solutions for logic / memory / image sensor.
  • Productivity improvement and Overlay Improvement options to balance throughput and overlay accuracy are available.

  • Color filter and other alignment system options established for earlier FPA-5550iZ steppers allow stable operation and flexibility for a variety of processes.
