ABSTRACT:
An organic inverter and a method of manufacturing the same are provided, which regulates threshold voltages depending on positions when an inverter circuit is manufactured on a substrate using an organic semiconductor. To form a depletion load transistor and an enhancement driver transistor at adjacent positions of the same substrate, the surface of the substrate is selectively treated by positions or selectively applied by self-assembly monolayer treatment. Thus, a D-inverter having a combination of a depletion mode and an enhancement mode is more easily realized than a conventional method using a transistor size effect. Also, the D-inverter can be realized even with the same W/L ratio, thereby increasing integration density. That is, the W/L ratio does not need to be increased to manufacture a depletion load transistor, thereby improving integration density.
