ABSTRACT:
A laser processing process which includes laser annealing a silicon film 2 .mu.m or less in thickness by irradiating a laser beam 400 nm or less in wavelength and being operated in pulsed mode with a pulse width of 50 nsec or more and preferably, 100 nsec or more. The invention further relates to a laser processing apparatus which includes a laser generation device and a stage for mounting thereon a sample provide separately from said device, to thereby prevent transfer of vibration attributed to the movement of the stage to the laser generation device and the optical system. A stable laser beam can be obtained to thereby improve productivity.
