Patent ID: 7459721

Claim:
A process for producing a field effect type organic transistor having a source electrode, a drain electrode, a gate electrode, a gate insulating layer, and an organic semiconductor layer, the process comprising the steps of: forming the gate insulating layer containing an optical anisotropic material; and forming the organic semiconductor layer in contact with an anisotropic structure formed by irradiation of light to the optical anisotropic material, wherein the optical anisotropic material is represented by one of the following formulas (H1) through (H4): where R represents H, a halogen, CN, CF 3 , or an alkyl or perfluoroalkvl group of 1 to 20 carbon atoms: in the alkyl, one or more of methylene groups may be replaced by O, CO, NH, or S; X represents an alkylene group of 1 to 20 carbon atoms: in the alkylene, one or more of methylene groups may be replaced by O, CO, NH, or S; A represents —CH—CH 2 —, —C(CH 3 )—CH 2 —, or —SiZ-O—: Z representing an alkyl or alkoxy group of 1 to 20 carbons; and n represents an integer showing a polymer, ranging from 10 to 100,000 corresponding to a number-average polymerization degree.
