The Horizon Pitch Changer will transfer 25 wafers between one standard pitch plastic cassette to one custom pitch quartz or silicon carbide process boat.
As with all Mactronix wafer transfer systems, the Horizon Pitch Changer may be configured to accommodate a wide range of Plastic, Teflon®, Metal, Quartz, Silicon Carbide, and Polysilicon carriers.
The Horizon Series V machines are designed to limit particle contamination by using lead screw drive and stepper motor, “clean room grade” rails and bearings and electric boat sensors.
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 for both personal safety and machine safety 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%.
