  • Organic Thin Film Transistors, Active Matrix Organic Optical Devices and Methods of Making the Same
    Publication number: 20100264408
    Abstract: A method of manufacturing an organic thin film transistor, comprising: providing a substrate comprising source and drain electrodes defining a channel region; forming a patterned layer of insulting material defining a well surrounding the channel region; depositing a protective layer in the well; subjecting exposed portions of the patterned layer of insulating material to a de-wetting treatment to lower the wettability of the exposed portions; removing the protective layer; and depositing organic semiconductive material from solution into the well.
