Abstract

The electrical characteristics of organic thin-filmtransistor (OTFTs) can be improved by inserting adhesion layer on gate dielectrics. Adhesion layer was used as polymeric adhesion layer deposited on inorganic gate insulators such as silicon dioxide $(SiO_2)$ and it was formed by vapor deposition polymerization (VDP) instead of spin-coating process. The OTFTs obtained the on/off ratio $of{\sim}10^4$, threshold voltage of 1.8V, subthreshold slop of 2.9 V/decade and field effect mobility about $0.01\;cm^2/Vs$.
