"MATERIALS: Silicon circuits made ink-jet printable"

Silicon ink for printing electronic circuitry atop flexible foil substrates was unveiled today at the Printed Electronics conference (Nov. 12-15, 2007, San Francisco). Kovio, Inc. (Sunnyvale, Calif.) described its "green" silicon ink for thin-film transistors (TFTs) that achieve the performance of polysilicon transistors, but at a third their price and consuming only 5 percent of the chemicals and 25 percent of the energy of single-crystal silicon. Kovio claimed that radio-frequency identification tags using its silicon ink will drop Kovio's price from 15 cents today to 5 cents by 2008, when Kovio begins volume production of its inkjet-printed RFID tags.
