Abstract

An object of the invention is to provide a method for manufacturing semiconductor devices that are flexible in which elements fabricated using a comparatively low-temperature (less than 500° C.) process are separated from a substrate. After a molybdenum film is formed over a glass substrate, a molybdenum oxide film is formed over the molybdenum film, a nonmetal inorganic film and an organic compound film are stacked over the molybdenum oxide film, and elements fabricated by a comparatively low-temperature (less than 500° C.) process are formed using existing manufacturing equipment for large glass substrates, the elements are separated from the glass substrate.
