ABSTRACT:
In irradiating and scanning an amorphous silicon film formed on the glass substrate with a linear laser beam, the glass substrate is placed so as to assume a convex surface. In a heated state, the amorphous silicon film is irradiated and scanned with the linear laser beam having an inverted-U-shaped focus line that approximately coincides with the convex surface. Slow cooling is thereafter performed. A silicon film having uniform crystallinity is formed on a glass substrate having flat surface. Also, A thin film transistor (TFT) having a uniform threshold voltage is produced by using the crystalline silicon film.
