Printed electronics processing and applications in memory devices and TFTs
Using printing is expected to enable low-cost mass-fabrication of large-area electronics. Different fabrication paradigms such as sheet-to-sheet (S2S) and roll-to-roll (R2R) are under development. Limitations of different printing methods will be discussed for the processability of the materials, for example, in terms of annealing conditions and positioning accuracy of consecutive device layers. Printed memory devices and TFTs are highlighted because they set demanding requirements for the printing process as well as for the materials. Emerging techniques to improve on the processing accuracy are reviewed.
