Abstract
The present invention provides an organic single crystal field effect circuit and method for preparing the same. The method comprises the steps of: preparing circuit masks; preparing a flexible planar embedded lamination electrode with the circuit patterns: 1) attaching octadecyl trichlorosilane on surface of a substrate; 2) preparing the source, drain and gate electrodes on the modified substrate, and attaching mercaptopropyl trimethoxysilane; 3) spin-coating polydimethyl siloxane on surfaces of the source, drain and gate electrodes, respectively; 4) removing the gate electrode spin-coated with polydimethyl siloxane, performing oxygen plasma treatment to the metal electrode surface of the gate electrode and polydimethyl siloxane surfaces of the source and drain electrodes, respectively, to form hydroxyl; 5) adjusting the source and the drain electrodes, attaching the gate, source and drain electrodes into an integration, thereby obtaining the flexible planar embedded lamination electrode; preparing the organic single crystal field effect circuit. The present invention prepares electrodes using photolithography technique with high precision such that patterns with high precision and high complexity can be prepared, which is convenient and practicable.
