Features & Benefits

  • Mactronix Wafer Lifter Automatic (WLO), automatically aligns wafer flats followed by successive raising of the wafers on an incline.
  • Cross-slot detection and wafer mapping.
  • Capable of automatic indexing for reading wafers with two scribes.
  • The main function is to read scribes on the wafers, along the flat. 
  • After all lot reading is done, it can report to the fab host via RS232.
  • The machine may be configured to accommodate a large diversity of Plastic, Teflon® carriers.
  • With the push of a button, the machine raises wafers automatically for individual wafer identification and edge inspection.
  • Both flat finding and wafer lifting is switch selectable.
  • Once flat finding is selected the flat finding operation is automatic with no additional operator input other than carrier placement upon the machine.
  • By operator selection, the wafers may be raised for inspection and lowered at any time after the flat finding operation.
  • As a convenience, the foot print and weight of the WLO is small enough to be placed near any work environment.
  • Carrier sensors located in the platform prevent the machine from operating if the required carriers are not present.
  • Uptime will exceed  99.25%.
    • MTBF (mean time between failure): 2,500 hours
    • MTBA (mean time between assist): 1,000 hours
    • MTTR (mean time to repair): less than 1 hour


  • RS232 communications port 
  • Stainless steel covers
