ZiLOG
2002Quality and Reliability Report
FIT Measurement Direct and Indirect
Just as ZiLOG records its outgoing quality in terms of parts per million, it also measures its
outgoing product reliability in terms of “FITS” or Failures per billion device hours. This
calculation is done by using the results of weekly operating life test measurements on the
circuits performed in accordance with standard specifications.
Field Quality Engineers
ZiLOG maintains a force of skilled Field Application Engineers, who are also trained as Field
Quality Engineers. These engineers are available on immediate call to consult our customers on
any problems they may be experiencing with ZiLOG product performance.
Product Analysis
Product Analysis facilities, staffed by experienced professionals, exist at each ZiLOG site to
provide rapid evaluation of in-process and in-field rejects. ZiLOG is pleased to share product
analysis reports on specific products with the customer upon request.
Oxide Charge to Breakdown (Qbd)
Gate oxide quality for ZiLOG’s major fabrication processes is monitored weekly through
extraction of wafer level Qbd data from the parametric test database. ZiLOG’s Qbd test is based
on the J-ramp test specified in JEDEC Standard JESD35- “Procedure for the Wafer-Level
Testing of Thin Dielectrics.”
Statistical Process Control
ZiLOG employs Statistical Process Control at all critical process steps. Deviations from norms
must be evaluated by a Q/R review board.
Total Quality Program
ZiLOG employees actively participate in meetings where methods are proposed, reviewed, and
adopted. These meetings enable a department to do its job in a more precise and accurate
manner.
ZiLOG Vendor of the Year Award
ZiLOG is proud of the many quality and performance awards it has received from its customers.
In turn, ZiLOG makes an annual award to the vendor who has done the best overall job for
ZiLOG.
