PHOTO-CURABLE DIAMINE MONOMER AND POLYIMIDE, AND ORGANIC THIN FILM TRANSISTOR USING THE SAME AS INSULATOR

摘要

PURPOSE: A photo-curable diamine monomer and polyimide, and organic thin film transistor using the same as an insulator are provided to improve the packing density and insulating property of an organic insulator thin film as well as to improve the chemical resistance of the thin film. CONSTITUTION: In a photo-curable diamine monomer and polyimide, and organic thin film transistor using the same as insulator, the molecular weight of polyimide is within 5,000-1,000,000 g/mol. The intrinsic viscosity of the polyimide is within 0.1-1.5dL/g. The polyimide has an insulating film formation temperature of 100-300300°C.
