Abstract: PROBLEM TO BE SOLVED: To allow a combination of an organic semiconductor and an inorganic gate insulation layer with a high dielectric constant by combining a thin film gate insulator with a high dielectric constant, an organic semiconductor, a metal, a conductive polymer, and a heavily doped and highly conductive material. SOLUTION: A thin film gate insulator with a high dielectric constant such as a barium strontium titanate, an organic semiconductor such as pentasene, a metal, a conductive polymer, a heavily doped and highly conductive material as gate, source, and drain electrodes, and their combination are used to form a thin film transistor. In the structure thereof, an inorganic gate insulator with a high permittivity is used together with an organic insulator such as pentasene. The insulator with a high dielectric ε is annealed at 400 deg.C and the dielectric constant of ε>=15 can be realized. Therefore, a substrate made of glass or plastic can be used. The gate electrode can be formed of heavily doped silicon substrate as a gate.

Abstract: PROBLEM TO BE SOLVED: To impart vertical alignment and domain formation to a homeotropic pixel element of a liquid crystal display technique by using a technique to form a self-organizing monomolecular film. SOLUTION: A substituted silane compound such as octadecyl silane is applied to a transparent conductive layer surface of such as indium tin oxide as a hydrolysable alcoholic solution and a molecular layer with thickness of essentially one molecule (the monomolecular film) is formed via a baking temperature cycle. One terminal group of the monomolecular film is bonded to the indium tin oxide surface and the other terminal group functions so as to influence molecular alignment and domain formation of a liquid crystal material.
