摘要: Self-assembled monolayers (SAMs) have been used to improve both the positive and negative bias-stress stability of amorphous indium gallium zinc oxide (IGZO) bottom gate thin film transistors (TFTs). N-hexylphosphonic acid (HPA) fluorinated hexylphosphonic (FPA) SAMs adsorbed on IGZO back channel surfaces were shown significantly reduce bias stress turn-on voltage shifts compared with no SAMs. FPA was found a lower surface energy packing density than HPA, as well shifts. The improved TFTs can be primarily attributed reduction in molecular adsorption contaminants minimal trapping states present phosphonic binding surface.
