Abstract

The authors made amorphous silicon thin-film transistors on glass foil using exclusively electrophotographic printing for pattern formation, contact hole opening, and device isolation. Toner masks were applied by feeding the glass substrate through a photocopier, or from laser-printed patterns on transfer paper. This all-printed patterning is an important step toward demonstrating a low-cost large-area circuit processing technology.
