  • Patent number: 8013270
    Abstract: A laser processing apparatus includes a support table, a local exhaust device, and a laser light source unit. The support table supports a processing object. The local exhaust device directs laser light into a local exhaust unit in which pressure is locally adjusted over the support table. The laser light source unit outputs the laser light. The local exhaust device is capable of relatively being lifted from the support table by injecting a lift gas to the support table. The processing object includes a multilayer film formed of two or more layers with different materials. An input unit into which reflectance of the processing object is inputted is connected to the laser light source unit.
