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.
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.
