This fully automatic microprocessor controlled notch finder model provides for wafer notch finding with minimal
operator involvement. To align wafer notches, the operator places the carrier on the unit and pushes one of the
“RUN” switches. All wafer notches are automatically aligned to the bottom, then, relocated to one of the 16
positions as set by the operator. LED indicates cycle in process and end of cycle. Accuracy is better than plus or
minus one degree. No manual operation or override is available. Rotation is controlled at a constant speed for
minimal particulate generation. A 16 position rotary switch controls final wafer notch location. Standard adjustment
points are 0, 2, 45, 88, 90, 135, 176, 178, 180, 182, 184, 225, 270, 272, 315 and 358 degrees.
This fully automatic microprocessor controlled flat finder provides for wafer flat finding with minimal operator
involvement. To align wafer flats the operator places the carrier on the unit and pushed the “RUN” switch. All wafer
flats are automatically aligned to the bottom, and then relocated to one of the 16 positions as set by the operator.
Accuracy is better than plus or minus one degree. No manual operation or override is available. All rotation is
controlled at a constant speed for minimal particulate generation. Final wafer flat a 16 position rotary switch
mounted controls location near the RUN switch. Standard adjustment points are 0°, 2°, 45°, 88°, 90°, 135°, 176°,
178°, 180°, 182°, 184°, 225°, 270°, 272°, 315° and 358° degrees.
This manual flat aligner provides for top/bottom wafer flat alignments. To align wafer flats the operator places the
carrier on the unit and rotates the manual knob.  Unique wafer roller and alignment system gently captures and
positions the flats to the bottom of the cassette.  Operator can then rotate the roller alignment switch and
manually rotate the wafer flat position to any position on the radius. Open design allows increased laminar airflow
and improves cleanliness while minimizing footprint. EZ Guide positioners assure properly positioned cassettes.
ESD protected by static-dissipative plastics. Proprietary static-dissipative polyurethane roller withstands more
than 2,000,000 cycles with accuracy of better than 1 degree. Compatible with most standard plastic wet/dry
process cassettes, shipping and storage cassettes.

withstands more than 2,000,000 cycles with accuracy of better than 1° degree. Compatible with most standard
plastic wet/dry process cassettes, shipping and storage cassettes.
Manual aligners for wafer edge inspection applications. These custom product versions with special dual knob designs
aid operators who are turning the wafers slowly looking for defects.  These special aligners are useful for right and left
handed operators.
The “FFTBAS-456” model is for use in applications where metallic contamination or chemical attacks are
concerns. It is constructed from black static-dissipative Polypropylene, which has been custom manufactured to H-
Square specifications. This material has excellent chemical resistance and toughness. Since it is conductive, it will
not build up static charge, which can lead to circuit damage or act as a particulate magnet. Its proprietary
conductive Polyurethane roller (part # A000-379-2) provides a path from wafers to ground (ground wire included)
for ESD protection.This single model is compatible with most standard 4, 5, and 6-inch plastic wet/dry process
carriers, storage and shipping containers. Unit is NOT compatible with metal cassettes. Custom models are
available for metal cassettes and non-standard carriers
The “FFTB” model is the basis for H-Square top/bottom manual, top/bottom motorized and top/bottom semi-
automatic flat finders. They provide an efficient method of aligning primary or secondary wafer flats without
removal of wafers from the carrier. They are constructed of precision-machined, hard clear anodized, 6061 T-6
aluminum alloy for durability and long-during use. Motorized versions utilize industrial quality “D” cells (one per
motorized flat during use. Motorized versions utilize industrial quality “D” cells (one per motorized flat finder) and 9-
volt transistor batteries (one per semi-automatic flat finder).
This battery powered notch finder is designed to align SEMI standard notched wafers. Similar in principal to flat finders, it
uses a small diameter, nylon alignment roller to rotate the wafers. When the notch registers over the roller the wafers
cease rotation, leaving the notches aligned at the bottom. The roller is attached to a manual lifting mechanism. presses a
lift bar, which raises the drive roller. The roller lifts all wafers away from the notch alignment roller. The operator then
manually rotates the spinner knob to relocate plastic wet/dry process carriers and shipping/storage containers.

Unique thin wafer roller and alignment system gently captures and positions flats or notches for clean and accurate
operation. Special material roller resists the cutting action from accurate thin wafer rotation. Three roller design is
engineered to keep the wafers from contacting the side wall of the cassette to extend the cassette lifecycle and
eliminate edge chipping commonly associated with rotation of thin wafers with a standard aligner. EZ Guide positioners
assure properly positioned cassettes. ESD protected by static-dissipative plastics
Automatic aligner for wafer edge inspection applications. This custom product version features a PLC program edge
inspection routine to aid operators in turning the wafers slowly for a controlled amount of time. The remote control
allows the operator to STOP/PAUSE the run and or reverse direction to effectively find edge defects.  Normal aligner
programming leaves the wafers in +/- 1 degree of position after the edge inspection routine.
