We report on the fabrication of OTFTs with organic/inorganic passivation layers to enhance the long-term stability of devices. In order to obtain a flat surface on which an inorganic thin film could be deposited, an organic smoothing layer was employed. The planarization of the rough pentacene surface would induce a very smooth and dense surface for the inorganic layer as well. When the SnO2/PVA film was introduced as a component of the encapsulation, greatly enhanced barrier properties were observed. Our work demonstrated that organic/inorganic hybrid passivation layers are a promising technique for a long-term protection of OTFTs.
