Abstract: PROBLEM TO BE SOLVED: To realize a device which contains an N-channel semiconductor material that is stable in the air, transparent to visible rays, and indicates a specific field-effect electron mobility by adding condensed ring tetracarboxylic acid diamide compound to a thin film. SOLUTION: An N-channel semiconductor thin film contains a condensed ring tetracarboxylic acid diamide compound and indicates field effect electron mobility larger than 0.001 cm2/Vs. Naphathalene 1,4,5,8-tetracarboxylic acid diamide can be used as the above compound. This compound can be dissolved well into an ordinary organic solvent, and an active semiconductor thin film can be solution-deposited. The compound can be made very volatile so as to be easily vapor-deposited if necessary. Even if the compound is operated in the air, it indicates a desirably high mobility of an N-channel and a preferable ON/OFF ratio and is comparatively transparent to visible rays.
