Quality Assurance
1 Quality Assurance
The high quality and reliability of integrated circuits from
Siemens are the result of carefully managed design and
production which is systematically checked and controlled at
each stage.
The procedures are subject to a quality assurance system;
full details are given in the brochure “Quality Assurance
lntegrated Circuits”.
Figure 1 and 2
show the most important stages of the QA
system. Quality assurance (QA) departments, independent
of production and development, are responsible for the
selected measures, acceptance procedures and information
feedback loops. Operating QA departments have state-of-
the-art test and measuring equipment at their disposal, work
according to approved methods of statistical quality control,
and are provided with facilities for accelerated life and
environmental tests used for both qualification and routine
monitoring tests.
The latest methods and equipment for preparation and
analysis are employed to achieve continuity of quality and
reliability.

2 Conformance
Each integrated circuit is subjected to a final test at the end of
the production process. These tests are carried out by
computer-controlled, automatic test systems as hundreds of
thousands of operating conditions as well as a large number
of static and dynamic parameters have to be considered.
Moreover, the test systems are extremely reliable and
reproducible. The quality assurance department carries out a
final check in the form of a lot-by-lot sampling inspection to
additionally ensure the minimum percent defectives to
ensure statistically that the PDA of released lots is less than
the AQL agreed. Sampling inspection is performed in
accordance with the inspection plans of DIN 40080, as well
as of the identical MIL-STD-105 or IEC 410.
3.3 Reliability monitoring
The general course of IC failure rate versus time is shown by
a so-called “bathtub” curve.The failure rate has its peak
during the first few operating hours (early failure period). After
the early failure period has ended, the “constant” failure rate
period starts during which the failures may occur at an
approximately uniform rate. This period ends with a repeated
rise of the curve during the wear-out failure period. For ICs,
however, the latter period usually lies far beyond the service
life specified for the individual equipment. Reliability tests for
ICs are usually destructive examinations. They are,
therefore, carried out with samples. Most failure mechanisms
can be accelerated by means of higher temperatures. Due to
the temperature dependence of the failure mechanisms, it is
possible to simulate future operational behavior within a short
time by applying high temperatures; this is called life test. The
acceleration factor
F
for the life test can be obtained from
Arrhenius’s equation
E
A
1 1
- -
F
=
exp
-----
----- – -----

T

T

where
T
2
is the temperature at which the life test is
performed,
T
1
is the assumed operating temperature and
k
is Boltzmann’s constant.
Important for factor
F
is the activation energy
E
A
. It lies
between 0.3 and 1.3 eV and differs considerably for
individual failure mechanisms.
For all Siemens ICs the reliability data from life tests is
converted to an operating temperature of
T
A
= 55
°
C,
assuming an average activation energy of 0.5 eV. The
acceleration factor for life tests at 125
°
C is thus 22,
compared with operational behavior. This method considers
also failure mechanisms with low activation energy, i.e. which
are only slightly accelerated by the temperature effect.
Various reliability tests are periodically performed with IC
types that are representative of a certain production line this
is described in the brochure “Quality Assurance Integrated
Circuits”. Such tests are e.g. humidity test at 85
°
C and 85 %
relative humidity, pressure cooker test, as well as life tests up
to 1000 hours and more. Test results are available in the form
of summary reports.
3 Reliabilitiy
3.1 Measures taken during development
The reliability of ICs is already considerably influenced at the
development stage. Siemens has, therefore, fixed certain
design standards for the development of circuits and layout,
e.g. specifying minimum width and spacing of conductive
layers on a chip, dimensions and electrical parameters of
protective circuits for electrostatic charge, etc. An
examination with the aid of carefully arranged programs
operated on large-scale computers guarantees the
immediate identification and elimination of unintentional
violations of these design standards.
3.2 In-process control during production
The manufacturing of integrated circuits comprises several
hundred production steps. As each step is to be executed
with utmost accuracy, the in-process control is of outstanding
importance. Some processes require more than a hundred
different test measurements. The tests have been arranged
such that the individual process steps can be reproduced
continuously.
The decreasing failure rates reflect the never ending effort in
this direction; in the course of the years they have been
reduced considerably despite an immense increase in IC
complexity.
