PC - LARGE DIE SUBSTRATE CASSETTES AND LIFTER BLOCK

required the use of an ESD safe material - Pomalux.  A lifter block was
incorporated to be able to use an edge grip mechanical handling tool.  Contact
your H-Square sales representative for more information. Minimum order
quantities may apply.

PC - CLEANING FIXTURE APPARATUS
This PC cassette was designed to hold quartz cassette and SiC cassettes for a
cleaning application.  The handle design was custom ergonomically designed
for the wet bench attributes.  Contact your H-Square sales representative for
more information.  Minimum order quantities may apply.

PC - METAL - PLASTIC HYBRID CASSETTE
This PC cassette was designed to hold a 200mm thin silicon wafers where a thin film
coating was sticking to a PEEK cassette during the application.  The introduction of the
PTFE side walls solved this issue.  An aluminum end wall and h-bar preserved dimensional
stability in this thermal bake application.  Contact your H-Square sales representative for
more information.  Minimum order quantities may apply.
PC - PFA CASSETTE INSERT
existing PFA injection molded cassette to process smaller substrate size devices.  A lid was
engineered to keep the light weight substrates from floating out of the cassette in the wet
bench environment.  The application required that the larger existing PFA cassette be used
as the fab's wet bench automation and SRD - spin rinse dryers were already setup for this
cassette.  Note: SRD rotor re-balancing is required. Contact your H-Square sales
representative for more information.  Minimum order quantities may apply.

PC - LABORATORY BEAKER CASSETTE
This PC cassette and lid apparatus was designed to insert into an existing lab beaker in
order to process substrates in an R&D area. Contact your H-Square sales representative
for more information.  Minimum order quantities may apply.

PC - ANGLED COUCH CASSETTE
This PC cassette was designed to hold glass slides during inspection and cleaning.  The
material used was ESD safe Pomalux.  The unique design allowed operators to easily access
the edge of the substrate for loading into a microscope with a mechanical edge grip tool.  
Contact your local H-Square sales representative for more information.  Minimum order
quantities may apply.

PC - WET BENCH APPLICATION CASSETTES
Most PC cassettes are made from virgin PTFE so they are extremely chemical resistant.  This
application required a special "T" handle be designed to allow the operator to assist in wafer
agitation during the etch and clean process.  Contact your local H-Square representative for
more information.  Minimum order quantities may apply.
