Abstract: It is an object to provide a method of manufacturing a crystalline silicon device and a semiconductor device in which formation of cracks in a substrate, a base protective film, and a crystalline silicon film can be suppressed. First, a layer including a semiconductor film is formed over a substrate, and is heated. A thermal expansion coefficient of the substrate is 6×10−7/° C. to 38×10−7/° C., preferably 6×10−7/° C. to 31.8×10−7/° C. Next, the layer including the semiconductor film is irradiated with a laser beam to crystallize the semiconductor film so as to form a crystalline semiconductor film. Total stress of the layer including the semiconductor film is −500 N/m to +50 N/m, preferably −150 N/m to 0 N/m after the heating step.
