Holst Centre, imec and Evonik have realized a general-purpose 8-bit microprocessor, manufactured using complementary thin-film transistors (TFTs) processed at temperatures compatible with plastic foil substrates (250°C). The new “hybrid” technology integrates two types of semiconductors – metal-oxide for n-type TFTs (iXsenic, Evonik) and organic molecules for p-type TFTs – in a CMOS microprocessor circuit, operating at unprecedented for TFT technologies speed – clock frequency 2.1kHz. The breakt...
