Paper Abstract

Printed electronics is an emergent subject for the low-cost and large-area fabrication of flexible electronic devices. Direct printing of organic thin-film transistors (OTFTs) is a particularly promising fabrication method that can be used in large-scale production at low cost. In this work, we developed “room-temperature printed electronics”, which allows OTFT devices to be printed at room temperature without application of heat. The room-temperature fabrication process never causes any thermal damage to the flexible substrate. Thus the process allows very accurate and high-resolution patterning even on a flexible plastic substrate. We also developed the printing technique using patterned surface wettabilities on surface. Through this process, short-channel OTFTs having 1-um channel length were successfully demonstrated. These results suggest that printed electronics technologies are promising as a core technology for low-cost and high-performance printed electronics.
