H-Square wafer notch and flat aligners provide an inexpensive and accurate method of batch alignment of wafers to any angle.  They are
compatible with SEMI standard cassettes. EZ Guide models are constructed with advanced ESD safe materials and the open design stage is laminar
substrates.
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 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.

ANTI-STATIC PLASTIC TOP/BOTTOM MANUAL FLAT FINDER
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

TOP/BOTTOM MANUAL, MOTORIZED, and SEMI-AUTOMATIC FLAT FINDER
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).

MOTORIZED NOTCH 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.
