Production of Environmental Measures on Products
The FDK Group is committed to oﬀering eco-friendly and energy-saving products free of hazardous chemical substances
through the entire life cycle of them from development and design stages to disposal of them.

Oﬀering Super-Green Products with the Top Environmental Elements
In the Third Environmental Action Plan, the FDK Group is involved in development and provision of super-green products with top environmental elements, one step forward of the conventional green products.

Targets of the Third Environmental Action Plan
Provision of Super-Green Products by the end of FY 2006
・ Super Green Products are the advanced form of green products incorporating such properties as energy saving, 3R (Reduce,
Reuse, Recycle)-based design, and elimination of hazardous chemical substances. They are forerunners having the world s ﬁrst ,world s smallest , nation s ﬁrst , industry s ﬁrst , nation s smallest and industry s smallest characteristics, which are intended
to be released by the end of FY 2006.

Super-Green Products
In FY2005, the FDK Group was committed to producing supergreen products by extracting 11 themes. As a result, the ﬁrst
super-green product was born: ultra small multilayer power
inductor, MIPF 2520D Series. The inductor is the top runnerproduct in the world with its size reduced by 40% in volume
compared to the conventional eco-friendly products of similar
type. The FDK Group will continue its eﬀorts so that more
super-green products can be delivered to our customers.

Quality Assessment Simulation for
Lead-Free Solder using CAE*As lead-free solder doesn t contain lead, one of the hazardous
substances, its physical properties are diﬀerent from conventionalsolders. Due to this reason, it is essential to select appropriatematerials and design and manufacture parts in a way suitable forusing lead-free solders. Believing that disclosure of physical properties of the lead-free solders and analyze them are the best
way to realize using lead-free solders, the FDK Group develops
and uses a unique simulation technology. The technology incorporates the unique know-how of the FDK Group nourishedthrough manufacturing and the latest study results.

True Random Number (Physical Random Number) Generation IC RPG100B
Application

Generation of random number and encryption of information for network security, e- commerce, identiﬁcation,lottery, game, simulation, graphics, wireless LAN, computer and mobile devices

Features

With a random number generation circuit and an ampliﬁer embedded in the main
body, the product is used to generate true random number utilizing thermal noise
emitted inside the semiconductor. High quality random numbers that can highly withstand external noises can be generated by diﬀerential operation of two independentcircuits of thermal noise source for generating random numbers. Though the producthas a serial bit random number output and parallel bit random number veriﬁcation
circuit, the size is very small, 5mm×5mm.

Eco-FriendlinessCompared to the conventional ICs of RPG100, the performance is the same, but the size
is smaller by 69% in terms of actual implementation space. This can save the space ofboth inside and outside of the device in which the IC is mounted. Of course, the productcomplies with EU s RoHS Directive.

Voice from the Developer
The RPG100 can output unforeseeable uniform
random numbers at a high speed and withstandﬂuctuation of power supply and temperature,external noise and other environmental factors.
I believe the product will be one of the key
parts for security systems that will respond to ahigher security requirements expected in the
future, and amusement devices. An encryption
module using the RPG
100 is under development in cooperation
with other universities
such as Tsukuba
University.

Approaches to Totally Eliminate Hazardous Substances in Products

Targets of the Third Environmental Action Plan
To eliminate use of hazardous substances designated by Fujitsu Group in manufacturing products by the end of FY 2005,
except for those designated by RoHS whose elimination target is the end of December 2004
・ Use of hazardous substances listed in 31 categories of Fujitsu Group s list will be totally eliminated by the end of FY 2005.
・ For products shipped to Europe and covered under the RoHS Directive, use of mercury, hexavalent chromium compounds, PBB
and PBDE will be totally eliminated by the end of December 2004.

As a result of our activities, all chemical substances prohibitedamong the designated hazardous chemical substances by Fujitsu
were successfully eliminated from our products. As to thechemical substances required to be totally eliminated under the
RoHS Directives, they were totally eliminated from all products
shipped to Europe including those that substitutions wererequested by the customers, except for some, for which substitutions were not available due to the reasons of reliability assurance.
For the items which substitutions were not available, we willfurther examine how to do so and take necessary measures for
it. As to the materials such as plating materials, which inclusionof chemical substances prohibited by the RoHS Directive issuspected, we will measure them in-house to conﬁrm no such
substances are included in any of them.

Site Report

In conducting our research on chemical substances contained in
procured items, the scope of hazardous substances was reduced
from 1403 to 518 in line with the industrial trend. The reason
for the reduction is to accelerate the speed and increasing theaccuracy of the research activities to reduce workloads relating
to them. The activities were accompanied by collection of documents including a declaration of non-use of hazardous substances
to understand which substances are included in each procured
item. Items found as containing hazardous substances as aresult of our research were shifted to those don t contain them.
For the items that the business partner didn t reply to our survey
sheet or others which inclusion of hazardous chemical substanceswere highly likely, we inspected them by ourselves using an
X-ray ﬂuorescent spectrometer.
As to our in-process control, with a view of any products as
defective in terms of the quality assurance system (ISO9001), if
they contain hazardous chemical substances, a product quality
control system was established and has been in operation.
At the same time, FDK
