Abstract
It is an object of the invention to provide a lightweight semiconductor device having a highly reliable sealing structure which can prevent ingress of impurities such as moisture that deteriorate element characteristics, and a method of manufacturing thereof. A protective film having superior gas barrier properties (which is a protective film that is likely to damage an element if the protective film is formed on the element directly) is previously formed on a heat-resistant substrate other than a substrate with the element formed thereon. The protective film is peeled off from the heat-resistant substrate, and transferred over the substrate with the element formed thereon so as to seal the element.
