초록

The buffer layer was spin-coated on the dielectric layer of OTFTs to introduce the hydrophobicity for enhancing the device performance. this functional layer contains the water-proof ingredient to reduce the surface energy and more importantly, does not harm the dielectric property of the dielectric layer. With the help of proposed hydrophobic layer, the transistor showed dramatic improvement at electrical performance which was almost 20 times higher mobility compared to the non-treated case. And on/off ratio was also guaranteed as $10^{5{\sim}6}$.
