Cabot Superior MicroPowders facilitates fabrication of world's first inkjet printed plastic electronics

Cabot Corporation : 23 June, 2003  (Company News)
Cabot Corporation announced today that the digital electronic materials developed by its recently acquired Cabot Superior MicroPowders division, were successfully used in facilitating the fabrication of the first fully functional, inkjet printed, plastic electronics, active-matrix display. The display was recently presented at the Society for Information Display Conference in Baltimore, MD.
The display was developed using CSMP proprietary digital electronic materials technology. CSMP's digital electronic materials are conductive, resistive and dielectric materials designed specifically for digital deposition, such as inkjet printing, and processing at very low temperatures making them suitable for use with plastic electronics. The technology is expected to greatly simplify the manufacture of a wide range electronics products for industrial and commercial use.

To create the display, a low-temperature, digitally dispensable silver ink, one of several CSMP's digital electronic materials, was successfully integrated into an inkjet printed plastic electronics display backplane produced by Plastic Logic Limited ( Plastic Logic, the leading developer of plastic electronics technology, is developing active matrix backplanes for flat panel displays. Its technology is compatible with glass and flexible substrates as well as large area applications.

According to Dr. Toivo Kodas, CSMP Technical Director, ' SMP has been developing several exciting new classes of conductor, resistor and dielectric materials and their associated printing technologies for the last 5 years. In the next few years, we expect to see the emergence of a variety of applications for these materials, and are excited about the potential. These results for silver conductors were made possible with assistance from CSMP's partners in this area and with the Defense Advanced Research Projects Agency vision and funding from the Mesoscopic Integrated Conformal Electronics program,' Dr. Kodas said.

Dr. James Caruso, New Business Development Manager, CSMP siad, 'The successful construction of this Plastic Logic display points directly to the capability of CSMP's low temperature, digitally dispensable metallic conductors . The ability to digitally print high conductivity pure metals on low temperature substrates adds significant functionality to this display. With the incorporation of these conductive features, the display can operate a higher video rate, and has improved contrast.'

John Mills, VP Engineering, Plastic Logic said, 'We are delighted to be working with SMP; their unique materials have enabled us to print key parts of our display backplane. The combination of CSMP materials and our proprietary technology highly simplifies the backplane manufacturing process and will enable low-cost customizable displays on large and flexible substrates to be produced.'
