Patent ID: 7858969

Claim:
An organic thin film transistor (OTFT), comprising: a substrate; a gate disposed on the substrate; a gate insulator disposed on the substrate and covering the gate, wherein the gate insulator comprises a silicon-containing compound; an adhesive layer disposed on the gate insulator, wherein the adhesive layer has a hydrophobic surface above the gate and a first hydrophilic surface and a second hydrophilic surface on two sides of the hydrophobic surface, and the adhesive layer is a silane material layer such that a silanization reaction is between the surface of the gate insulator and the silane material layer; a metal nano-particle layer, a surface thereof being modified by a hydrophilic group, the metal nano-particle layer being disposed on the first and the second hydrophilic surfaces of the adhesive layer as a source and a drain, respectively; and an organic semiconductor layer disposed on the hydrophobic surface of the adhesive layer and on the metal nano-particle layer.
