Abstract:
A method of fabricating a semiconductor device, comprising the steps of:providing a translucent substrate having first and second surfaces, the second surface opposed to the first surface; forming a base film of a first thickness over the first surface of the translucent substrate; forming a region of the first thickness and a region of a second thickness smaller than the first thickness by etching a part of the base film; forming an island-like semiconductor layer over the base film and over the region of the first thickness and the region of the second thickness; and crystallizing the island-like semiconductor layer by irradiating a laser beam to the island-like semiconductor layer from an upper portion of the island-like semiconductor layer over the first surface of the translucent substrate and from a side of the second surface of the substrate through the translucent substrate.
