Organic transistor technology options for device performance versus technology options for increased circuit reliability and yield on foil

Last year, advances in organic device technology (such as device scaling, high K-dielectrics enabled a substantial progress in performance. This resulted in an increase in the data rate of plastic transponder circuits from about 2 kbit/s to EPC-compatible speeds (50 kbit/s). The organic semiconductor pentacene deposited from solution was replaced by a better-performing vapor-phase deposited pentacene, with a mobility being a factor of 3 higher. This paper present the design of a new organic transistor that increase the circuit reliability. This robust device technology enabled to design 64 bit organic RFID transponder chips.
