摘要:
The present invention provides a method of manufacturing a semiconductor device, including the steps of forming a metal oxide film made of a metal oxide having a decrease in standard free energy smaller than a decrease in standard free energy of hydrogen oxide or of carbon oxide, on an insulating film formed on a semiconductor substrate, forming a metal oxide film pattern by subjecting a treatment to the metal oxide film, and converting said metal oxide pattern into at least one of an electrode and a wiring made of a metal which is a main component constituting the metal oxide, by reducing the metal oxide film pattern at a temperature of 80.degree. to 500.degree. C.
