Investments
in new equipment and facility:
For the plasma etch process, auto etch systems
are installed and are running in production. These systems provide
increased uniformity, better selectivity and profile control on critical
layers of our integrated circuits. For thin films, the latest deposition
systems are installed to provide polysilicon, nitride, BPSG and LTO
films with better uniformity, lower particulates and added capacity.
For the photomasking process, the latest stepper is in place to support
the development of new fine line processes and provide improved alignment
on existing circuits with more critical tolerances. New tracks of
photo-resist coat equipment provide better image definition and lower
defect densities.

Preventative
maintenance and equipment upgrades:
Key equipment is continually added or our preventative
maintenance (PM) programs are preserved, insuring increased uptime
and processing consistency.
-
Real-time statistical process control (SPC):
We continually augment our SPC system with several
real time measurements. This proves to be especially beneficial on
equipment being maintained.

Operator
training:
We focus our efforts on improving the overall
quality of our wafer manufacturing processes. By insuring better consistency,
fewer errors and redundancy from cross training, these efforts result
in lower losses and shorter cycle times.
By
applying quality assurance to our fully automated barcode system, Supertex
takes an extra step beyond ISO 9001 quality standards. Barcoded product
packages and shipping containers offer easier identification, faster tracking,
expedited delivery, reduced handling, improved control and accelerated
time-to-production on the customer end. These added benefits to our customers
translate to better efficiency in the supply chain.
In
order to achieve continuous improvements, we train Supertex employees
to ask "what to improve" and "how to improve" without
resistance but with enthusiasm. We accomplish such results by providing
our people with the proper tools, skills, training and an environment
to assure success.
