The fabrication of electronic circuits by jet-printing can eliminate photolithography and offers the potential to reduce manufacturing cost. Techniques used to fabricate amorphous silicon and polymer semiconductor thin film transistors (TFT) by subtractive and additive jet-printed are described. TFT backplanes patterned entirely by jet-printing on glass and flexible substrates, with application to flat panel displays and x-ray imagers, are described.
