Abstract:
Systems and methods for producing thin film transistor structures useful in controlling electronic displays. Thin film transistors are fabricated using all-additive methods including printing techniques, soft lithography and material deposition methods. The thin film transistors can be deposited with the gate on the bottom or on the top of the structure. The deposition methods include the possibility of isolating nearly completely the transistor structure from the electronic display devices, so as to minimize or eliminate deleterious interactions therebetween.
Abstract:
A process for forming a relatively high quality, lower cost organic semiconductor film is provided. A substrate is formed by depositing an organic semiconductor film via a lower cost method such as printing or spin coating on a support substrate. A portion of a solvent is vaporized to bring the vapor into contact with the film. The chemical potential of the vapor molecules is controlled to provide an interaction with the organic semiconductor film to alter the molecular arrangement of the film. The process further entails placing the substrate on a first temperature controlled stage and placing the solvent on a second temperature controlled stage. The chemical potential of the vapor is adjusted by controlling the temperature of the solvent. Appropriate annealing conditions are obtained by adjusting the temperature of the solvent, the substrate, and the anneal time. The process can assist manufacturing of lower cost displays that utilize arrays of organic thin-film transistors.
