Abstract
The present invention provides a laser apparatus including a transmission-variable mirror and a method for forming a semiconductor device using the apparatus. For crystallizing an amorphous semiconductor film by irradiation of laser beams, a top surface and a back surface of the amorphous semiconductor film are irradiated with the laser beams. In this case, the transmission-variable mirror is used for dividing a laser light emitted from a laser source.
