ABSTRACT:
In order to realize a semiconductor device of enhanced TFT characteristics, a semiconductor thin film is selectively irradiated with a laser beam at the step of crystallizing the semiconductor thin film by the irradiation with the laser beam. By way of example, only driver regions (103in FIG.1) are irradiated with the laser beam in a method of fabricating a display device of active matrix type. Thus, it is permitted to obtain the display device (such as liquid crystal display device or EL display device) of high reliability as comprises the driver regions (103) made of crystalline semiconductor films, and a pixel region (102) made of an amorphous semiconductor film.
