Abstract
A laser processing apparatus includes a support unit that supports a wafer including a plurality of functional elements disposed adjacent to each other via a street, an irradiation unit that irradiates the street with laser light, and a control unit that controls the irradiation unit based on information about the streets so that a first region and a second region of the street are simultaneously irradiated with the laser light, and a power of the laser light for removing a surface layer of the street in the first region is higher than a power for removing the surface layer of the street in the first region. The information about the street includes information that a processing threshold value indicating a difficulty of laser processing in the first region is lower than a processing threshold value in the second region.
