Claim 14:
15. A wafer processing apparatus comprising:
a laser apparatus configured to generate a laser beam;
focusing lens optics configured to focus the laser beam on an inside of a wafer;
an arbitrary wave generator configured to supply driving power to the laser apparatus; and
a controller configured to control the arbitrary wave generator,
wherein the laser beam comprises a plurality of pulses sequentially emitted from the laser apparatus, and
wherein a rise time taken for an intensity of each of the plurality of pulses to rise from 10% of a peak point to 90% of the peak point is 1% or more of a full width at half maximum (FWHM) of each of the plurality of pulses and less than 50% of the FWHM.
