ORGANIC SEMICONDUCTOR FILM AND METHOD FOR MANUFACTURING THE SAME, AND STAMP FOR CONTACT PRINTING

摘要

Disclosed is an organic semiconductor film (10) which has a value of 1 or more but less than 10 for the ratio of the charge mobility [(charge mobility of the surface side having larger charge mobility)/(charge mobility of the surface side having smaller charge mobility)] of two opposing surface sides (11, 12). In addition, the organic semiconductor film (10) has a relative X-ray reflectance peak height of 2.0 or more with respect to the peak height of an organic semiconductor film which has the same thickness and materials and is manufactured by performing spin coating on a silicon wafer. Alternatively, the organic semiconductor film (10) has a value of 2 or more for the ratio of the charge mobility [(charge mobility of the surface side having larger charge mobility)/(charge mobility of the surface side having smaller charge mobility)] of the two opposing surface sides (11, 12).
