cintelliq ltd: Organic semiconductor industry races towards all
printed 13.56 MHz RFID tags
(M2 PressWIRE Via Acquire Media NewsEdge)
RDATE:09092008
Cambridge, UK -- The idea of RFID tags that are cheap enough to be as
ubiquitous as barcodes has been a long held vision. To achieve this
requires RFID tags that cost less than one euro cent each. While
current RFID tags based on silicon are capable of meeting the required
technical performance, they fail to meet the challenging cost target.
Lowering the cost or RFID tags requires a new approach.
The most promising alternative to silicon is organic semiconductors.
Organic semiconductors are carbon-based materials that can be used to
make transistors and rectifying diodes; two important components for an
operational RFID transponder. Key research institutions and start-ups
across the world have, over the past few years, raced to push the
performance of materials and device architectures to the point where
they have successfully demonstrated organic RF tags and organic RFID
tags operating at 13.56 MHz. These demonstrators have been made from
individually printed components such as capacitors, diodes and
transistors that are then connected together or else use
photolithography to pattern the transistors and diodes. None have been
truly printed on a single substrate.
On 30 September 2008, at the Organic Semiconductor Conference (OSC-08)
in Frankfurt, Professor Cho from Sunchon University, Korea, will
present for the first time an all printed 13.56 MHz 1 bit RFID Tag. The
realisation of an all printed RFID is seen as an important step towards
achieving truly low cost RFID tags that are manufactured by the mile.
Using only a gravure printer, a pad printer and an ink-jet printer the
researchers were able to fabricate a complete operational 13.56MHz RFID
tag including antenna, rectifier, and ring-oscillator.
For the printable rectifier the researchers invented a new Schottky
diode based on Ag, ZnO and Al-Si alloy inks. For the printable
transistors, used for the ring oscillators, the researchers used single
walled carbon-nanotubes (SWCNT), which are also a member of the organic
semiconductor family.
In addition to the work by Sunchon University, delegates attending
OSC-08 will be able to learn first-hand how leading organisations are
making rapid progress in developing materials, device architectures and
processing for transistors and diodes. A number of key developments
relevant to organic RFID are to be presented including papers by IMEC
on perfecting high-frequency rectifiers for organic RFID tags; and the
Advanced Institute of Science and Technology (AIST) on developing novel
approaches for printing RFID tags. On the broader topic of transistors
this year OSC will feature papers on novel approaches to producing
small geometry (University of Tokyo), low-voltage transistors and
complementary circuits (Max Planck Institute) and novel
solution-processable materials for transistor circuits (Polyera).
Now in its sixth year, OSC-08 runs from 29 September to 1 October at
the Frankfurt Messe, Germany. For more information see

Notes to editor
OSC-08 is the premier international event for scientists, engineers,
manufacturers and investors in organic semiconductor technologies and
organic electronics.
The OSC conference is hosted by cintelliq which founded the conference
series in 2003. cintelliq renamed the event OEC (Organic Electronics
Conference) in 2006 and 2007 to reflect its conference partnership with
the OE-A. With the ending of this partnership cintelliq continues to
hold an annual conference under the OSC brand.
