Processing Technologies for Thin Film Transistors from Organic Semiconducting Materials

Organic and polymeric semiconducting materials are of great interest recently because of their potential applications in light emitting diodes, photovoltaic cells, and thin film transistors (TFTs). For low-cost and disposable electronics, such as electronic price tags and simple displays, the development of high performance organic TFTs will be the key element. Organic transistors offer opportunities for low-cost fabrication from solution or low temperature vacuum evaporation. Much progress has been made in recent years in material and fabrication. Some aspects in processing related areas will be discussed here.
