METHOD OF REDUCING THIN FILM ON LOW TEMPERATURE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a method of reducing a thin film on a low temperature substrate.SOLUTION: A method of preparing a conductive thin film on a substrate is disclosed. First a reducing metallic compound and a reducer are dispersed in a liquid. Then, this dispersed liquid is deposited on a substrate as a thin film. Then, the thin film with the substrate is exposed to pulsed electromagnetic radiation for chemically reacting between the reducing metallic compound and the reducer to make the thin film conductive. This invention provides a method of providing activation energy to perform an oxidation reduction reaction in a thin film using strong pulsed light. This redox reaction may be reduction of a metallic oxide by an organic compound or may be performed on a low temperature substrate.
