Abstract

In this paper, it was demonstrated that organic thin-film transistors (OTFTs) were fabricated with the organic passivation layer by vapor deposition polymerization (VDP) processing, In order to form polymeric film as an passivation layer, VDP process was also introduced instead of spin-coating process, where polymeric film was co-deposited by high-vacuum thermal evaporation from 6FDA and ODA followed by curing, Field effect mobility, threshold voltage, and on-off current ratio with 450-nm-thick organic passivation layer were about $0.21\;cm^2/Vs$, IV, and $1\;{\times}\;10^5$, respectively.
