April 19, 2004 – Xerox Corp. has developed a semiconductive ink that could make it possible to create low-cost, flexible transistor circuits by inkjet printing or other common techniques, according to a news release.
The ink can be used to print the semiconductor channels of transistors at low temperatures and in open air, which is required for low-cost manufacturing. Current methods require processing at high temperatures and under inert atmospheres, the release said.
Xerox also announced it has developed materials for printing the other components — a conductor and dielectric — necessary to make a plastic circuit. The technology could lead to cheaper flat-panel and flexible displays, as well as radio-frequency identification tags.
