Hitachi’s RFID powder freaks us the heck out

RFID ‘Powder’ – World’s Smallest RFID Tag
The world’s smallest and thinnest RFID tags were introduced yesterday by Hitachi. Tiny miracles of miniaturization, these RFID chips (Radio Frequency IDentification chips) measure just 0.05 x 0.05 millimeters.
The previous record-holder, the Hitachi mu-chip, is just 0.4 x 0.4 millimeters. Take a look at the size of the mu-chip RFID tag on a human fingertip.
(Hitachi mu-chip tiny RFID tag) Now, compare that with the new RFID tags. The “powder type” tags are some sixty times smaller.
(Powder RFID chips next to a human hair) The new RFID chips have a 128-bit ROM for storing a unique 38 digit number, like their predecessor. Hitachi used semiconductor miniaturization technology and electron beams to write data on the chip substrates to achieve the new, smaller size.
Hitachi’s mu-chips are already in production; they were used to prevent ticket forgery at last year’s Aichi international technology exposition. RFID ‘powder,’ on the other hand, is so much smaller that it can easily be incorporated into thin paper, like that used in paper currency and gift certificates.
Science fiction fans will have a field day with this new technology. In his 1998 novel Distraction, Bruce Sterling referred to bugged money:
They always played poker with European cash. There was American cash around, flimsy plastic stuff, but most people wouldn’t take American cash anymore. It was hard to take American cash seriously when it was no longer convertible outside U.S. borders. Besides, all the bigger bills were bugged. (Read more about bugged money)
These tiny RFID tags could be worked into any product; combined with RFID readers built into doorways, theft of consumer goods would be practically impossible. It’s not clear from the references provided, but even if this chip needs an external antenna, the attached antenna would be a tiny ribbon of wire more narrow than a human hair and only a fraction of an inch long.
How far away could you be, and still read the information from this “powder RFID?” The source article is very thin; however, the mu-chip mentioned earlier is readable from a distance of 25 centimeters (about ten inches) with an external antenna like the one mentioned in the preceding paragraph. This doesn’t sound like much, but it’s certainly enough to read people going through doorways, for example.
These devices could also be used to identify and track people. For example, suppose you participated in some sort of protest or other organized activity. If police agencies sprinkled these tags around, every individual could be tracked and later identified at leisure, with powerful enough tag scanners.
To put it in the context of popular culture, see the picture below, which was taken from the 1996 movie Mission Impossible. One of the IMF operatives places a tracking tag on the shoulder of a computer programmer. Pretty clunky-looking tag…
(Tracking and ID tag from Mission Impossible movie) Take a look at these earlier stories related to RFID, and consider how much easier it will be with tinier chips: RFID Sensor Tag Shower For Disasters (gentle rain of RFID), RFID-Maki: Easy Payment Sushi (just tag the sushi directly, then scan customer’s stomach [no joke, see digestible tags]) and VeriChip Chairman Proposes RFID Chips For Immigrants (just dust the border).

The World’s Smallest RFID IC µ-Chip(2.45GHz):HITACHI
Hitachi Unveils Smallest RFID Chip
The Japanese chipmaker recently showed off an RFID microchip that is just 0.3 square millimeter square.
March 14, 2003 – Hitachi, the Japanese semiconductor company, has unveiled a prototype for the next generation of its µ-Chip (pronounced mu-chip). The chip is just 0.3 millimeters square, roughly half the size of the smallest RFID chip on the market.
The decrease in size was achieved by employing semiconductor fabrication processes that creates structures on the wafer that are just 0.18 microns. Most existing RFID chips use older 0.35 micron processes. The prototype of the mu-chip was shown at the International Solid-State Circuits Conference held in San Francisco, Calif., last month.

| Mu-chips get smaller |
The chip operates at 2.45 GHz and stores a 128-bit number based on the “mu-chip ID number criterion” developed by Hitachi, which issues the numbers. The number is written to the chip during the silicon fabrication process and cannot be changed. The current mu-chip can be read from about a foot away (30 cm). The new version is expected to maintain the same performance standards.
Another innovation in the new mu chip involves the electrodes, where the ends of the coiled antenna are attached. These are usually on the top of the chip, but on the new mu-chip, one is on the top and one is on the bottom. Hitachi says this will dramatically improve its ability to mass-produce RFID tags with mu-chips.
With very small chips, it becomes difficult to attach the antenna using conventional flip chip technology, in which the electrodes are coated with adhesive, and then the chip is turned over and pressed onto the antenna. Hitachi decline to describe the mass production technique it uses to attach the antennas for competitive reasons.
Hitachi currently sells RFID inlets (the chip with an antenna attached, on a substrate) for 50 yen (43 US cents) for orders of 70,000 or more. Readers currently cost about $1,500. The company has not established pricing for the new chip, but a spokesperson for Hitachi told RFID Journal that the company plans to sell complete systems — tags, readers, software and networking infrastructure — in 2005.
Hitachi sees the mu-chip as an attractive alternative to applications where a bar code isn’t suitable and more conventional RFID tags are too expensive. Among the markets it is targeting are supply chain management, product tracability, and security applications.
A number of Hitachi divisions are already using the mu-chip. And Marubeni-Itochu Steel has purchased tags for tracking items. The mu-chip doesn’t conform to any international standards, so it is currently being used in closed-loop applications.
