Abstract

A newly developed OTFT manufacturing process using the combination of self-assembly techniques and vapor phase polymerization method revealed that a thick $SiO_2$ dielectric layer (100~200 nm) is not well compatible with conducting polymer electrode, thereby resulting in still recognizable contact resistance, unstable $V_{th}$ and leaking off current. A couple of very recent studies showed that this issue may be solved by replacing such inorganic dielectric with a self-assembled monolayer or multilayer (organic) dielectric. Therefore, this short review introduces recent trends in the development of high performance thin film transistor consisting of both organic semiconductor and SAM dielectric.
