Abstract
A laser processing apparatus includes: a laser oscillator configured to oscillate a laser pulse; a first laser deflection unit configured to deflect the laser pulse emitted from the laser oscillator in a two-dimensional direction; a second laser deflection unit having a slower operation speed and configured to deflect the laser pulse emitted from the first laser deflection unit in a two-dimensional direction on a same plane; a laser oscillation control unit configured to control the laser oscillator; and first and second laser deflection control units respectively configured to control operations of the first and second laser deflection units. The first laser deflection control unit controls the first laser deflection unit to successively irradiate the laser pulse to multiple sites along a predetermined track in each of the processing positions in turn, and to change energy of the laser pulse emitted therefrom in a middle of repeated irradiation.
