Patent ID: 7265377

Claim:
An organic semiconductor device having an electrode for bias application, comprising: a substrate, an organic semiconductor, an insulator; and a conductor, wherein at least one compound constituting the insulator has a silsesquioxane skeleton of the Formula 1: where R 1 , R 2 , R 3 , and R 4 each represent one of a substituted or unsubstituted alkyl group having 1 to 5 carbon atoms and a substituted or unsubstituted phenyl group, and R 1 , R 2 , R 3 , and R 4 may be the same functional group or functional groups different from one another, m and n each represent an integer of 0 or more, and the sum of m and n is an integer of 1 or more, the skeleton may be of a random copolymer or a block copolymer.
