Abstract

This invention is designed to form thin films of metal sulfides usable in various types of electronic devices with a simple process comprising forming a layer of an organometallic compound having at least one metal-sulfur or metal-oxygen bond in the molecule on a substrate by printing or other means and then thermally decomposing the formed organometallic compound layer in an inert gas which may or may not be mixed with hydrogen sulfide.
