Patent ID: 7435989

Claim:
A semiconductor device comprising: a substrate; a layer containing one or more kinds of polymer compounds on the substrate; and an organic semiconductor layer in contact with the layer containing the one or more kinds of polymer compounds, wherein at least one kind of the one or more kinds of polymer compounds comprises a polymer compound having one or more secondary or tertiary aliphatic amino groups, wherein the one or more aliphatic amino groups is present in at least one of a side chain and a branched chain of the polymer compound having the one or more aliphatic amino groups, wherein the layer containing the one or more kinds of polymer compounds contains polysiloxane compounds, and wherein at least one kind of the polysiloxane compounds comprises a compound having a siloxane structure represented by any one of the following general formula (4), the following general formula (5), and the following general formula (6): where R 15 , R 16 , R 19 , R 20 , R 22 , R 25 , R 26 , and R 28 each in dependently represent a hydrogen atom, a substituted or unsubstituted alkyl group, alkenyl group, or alkynyl group having 1 to 12 carbon atoms, a benzyl group, a phenethyl group, or a styryl group; any one combination of R 15 and R 16 , R 19 and R 20 , R 19 and R 22 , and R 25 and R 26 may bind to each other to form a ring structure; one of R 15 and R 16 represents a substituent except a hydrogen atom; R 17 , R 21 , R 23 , R 27 , and R 29 each represent a divalent organic group which has 1 to 12 carbon atoms and which is not directly bound to an aromatic ring; R 18 , R 24 , and R 30 each represent a hydroxyl group, a substituted or unsubstituted alkyl group, alkenyl group, alkynyl group, or alkoxyl group having 1 to 12 carbon atoms, a benzyl group, a phenethyl group, a styryl group, or a siloxane unit; r, s, and t each represent an integer of 1 or more; and u represents an integer of 2 or more.
