2002Quality and Reliability Report
ZiLOG’S QUALITY AND RELIABILITY PROGRAM
ZiLOG, Inc. has an excellent reputation for the quality and reliability of its products.
ZiLOG’s Quality and Reliability Program is based on careful study of the principles laid down
by such pioneers as W. E. Deming and J. M. Juran. Even more importantly, we have benefited
from the observation and practical implementation of those principles as practiced in Japanese,
European and American manufacturing facilities.
The ZiLOG program begins with employee involvement. Whether the judgment of our
performance is based on perfection with incoming inspection, trouble free service in the field,
or timely and accurate customer service, we recognize that our employees ultimately control
these factors. Hence, our quality program is broadly shared throughout the organization.
Harmony Between Design and Process
High product quality and reliability in VLSI products is possible only if there is structural
harmony between product design and manufacturing. Great care is taken to ensure that the
statistical process control limits observed within the manufacturing plants properly guardband
the design technology used to configure the circuit and layout in ZiLOG’s automated design
methodology.
Through use of a technique which we call Process Templating, the technology file in the
automated design system is periodically updated to ensure that product design parameters fall
within the statistical control limits with which the process is actually operated. In simple terms,
the Process Template is the profile displayed by the process evaluation parameters which are
automatically recorded from the test patterns on wafers as they proceed through the production
line. These parameters are translated into the design technology file attributes so every product
design bears a lock and key relationship to the process.
Training
The integrity of our product design and manufacturing process depends on the skills of our
employees. ZiLOG training emphasizes the fundamentals involved in product design and
processing for quality and reliability.
Customer Service, an important aspect of ZiLOG’s quality performance as a vendor, also
depends upon our people clearly understanding their jobs and our obligations to our customers.
This aspect of training is also a part of the overall curriculum administered by ZiLOG.
