The smallest, thinnest chip in the world

Hitachi, the world's smallest and smallest chip, can be used in a variety of industries.

At an extremely small size: 0.15 x 0.15 mm and a thickness of only 7.5 micrometers, this RFID chip broke the microchannel of the " μ- Chip "(0.4 x 0.4 mm) also manufactured by Hitachi. Hitachi has used semiconductor miniaturization and electron beam technology to write data onto the chip. Named " Powder, " this chip has a 128-bit ROM (read-only memory) that stores 38-digit numbers.

To bridge the gap between parts of the chip, Hitachi has used SOI (Silicon-on-Insulator) technology, which is insulated from silicon.

Compared with other technologies, this technology significantly reduces parasitic capacitance and leakage current, which enhances the performance of transistors. In addition, the SOI also helps prevent interference of surrounding devices with the chip's performance.

According to Hitachi, the ' Powder ' chip can be used in many areas, such as home electronics, transportation, logistics and military.

According to Hitachi, with the existing compactness and slimness, the new RFID chip can be integrated into thin paper, as in the case of a banknote, to create a ' pre-recorded ' (bugged money) for eavesdropping.

In the military, this chip can be used in 'Grain dust smart' (Smart Dust) - a type of sensor tiny, technology use microelectromechanical (MEMS) wireless to detect any current What, from light, temperature to vibration.
