Vertical Wafer transfer Systems

Different models possible

1, 2  or 3 stage, moving heads etc

• The Horizon Series V will transfer a maximum of 25 wafers between two cassettes, two process boats or one process boat and one cassette. Senior series can handle up top 75 wafers
• As with all Mactronix wafer transfer systems, the Horizon Series may be configured to accommodate a wide range of Plastic, Teflon®, Metal, Quartz, Silicon Carbide, and Polysilicon carriers.
• PLC controlled enhancing the transfer machine’s simplicity.
• With the push of a button, the machine transfers wafers safely and automatically.
• The Horizon Series V machines are designed to limit particle contamination by using a stepper motor w/lead screw, “clean room grade” rails and bearings and a 1.25″ non-process exhaust port.
• The machine will not introduce more than 1.5 particles, greater than .23 micron in diameter, per wafer per transfer (machine must be exhausted to achieve this figure).
• All aluminum parts are hard black anodized for corrosion resistance.
• Electronic through beam sensors are used to detect wafer presence in boats and retainers thus preventing accidental double loading and scratches.
• Lift system uses ramped speed controls for gentle pick-up and landing.
• Pressure sensors are used both for personal safety and to prevent wafer damage by inhibiting machine operation.
• Retainers default to closed position to prevent the dropping of wafers in the event of a power disruption or a loss of air pressure or both.
• A “Maintenance/Cleaning Mode” is provided to facilitate preventative maintenance.
• The Series V machines have been tested with up to 50,000 volts of electrostatic discharge without disruption to internal electronics. The Series V machines are virtually immune to RFI noise, EMF, and ESD.
• 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): 1 hour
• PLC controller is equipped with an RS422 communications port.
