We have investigated the stability of the electrical performances in staggered organic thin film transistors (OTFTs) manufactured by using a CYTOP fluoropolymer as a gate dielectric, after the devices underwent reliability cycles in a high moisture and temperature controlled environment chamber. The results of such testing cycles showed a very high stability against the environmental conditions that might be related to the device top-gate structure, working as an efficient encapsulation, and to the hydrophobic properties of the fluoropolymer used as gate dielectric.

Abstract
We have investigated the stability of the electrical performances in staggered organic thin film transistors (OTFTs) manufactured by using a CYTOP fluoropolymer as a gate dielectric, after the devices underwent reliability cycles in a high moisture and temperature controlled environment chamber. The results of such testing cycles showed a very high stability against the environmental conditions that might be related to the device top-gate structure, working as an efficient encapsulation, and to the hydrophobic properties of the fluoropolymer used as gate dielectric.File in questo prodotto:
