    • A method for fabricating a semiconductor device is provided to form a crystalline silicon layer while suppressing a crack in a glass substrate or a layer formed on the glass substrate by forming a layer with compressive stress on the glass substrate so that the tensile stress of the surface of the glass substrate is decreased. A layer including a semiconductor layer is formed on a glass substrate(100) whose thermal expansion coefficient is more than 6x10^-7/°C and less than 38x10^-7/°C. The layer including the semiconductor layer is heated. A laser beam(104) of pulse oscillation is irradiated to the layer including the semiconductor layer so that the semiconductor layer is melted and the grain of the semiconductor layer is grown in a horizontal direction with respect to the glass substrate. The laser beam is ultraviolet rays, having a width not more than 100 mum. The ratio of the length of the laser beam to the width of the laser beam is not less than 1:500, and the half width of the profile of the laser beam is not more than 50 mum. The general stress of the layer including the semiconductor layer is not less than -500N/m and not more than +50N/m. The layer including the semiconductor layer can be composed of a silicon oxynitride layer and an amorphous silicon layer(103) that are sequentially stacked on the glass substrate.
