ORGANIC FIELD EFFECT TRANSISTOR WITH ORGANIC DIELECTRIC

摘要

PROBLEM TO BE SOLVED: To provide a technique to process a high-quality organic field effect device by improving an interface of an organic semiconductor and a gate insulator by the choice of materials and preparation conditions.

SOLUTION: A technique of processing a high-quality organic field effect device comprises steps of: depositing from a solution an organic semiconductor layer 3; and depositing from a solution a layer 2 of low permittivity insulating material forming at least a part of a gate insulator, such that the low permittivity insulating material is in contact with the organic semiconductor layer 3, in which the low permittivity insulating material is of relative permittivity from 1.1 to below 3.0.
