Abstract

Even in the case where an underlayer differs or a film thickness varies, high-quality repair is allowed to be performed. When a laser repair method performs repair work by setting a laser irradiation area for a defect part of a multi-layer film substrate and irradiating the defect part with a laser beam under a set laser working condition, the laser repair method includes: identifying a peripheral region of a laser beam irradiation position; dividing the identified peripheral region into a plurality of divided regions for each common reflected light information; inferring a layer structure at the laser beam irradiation position from analogy based on an arrangement pattern of the divided regions positioned around the laser beam irradiation position; and setting the laser working condition of the laser beam to be emitted based on the layer structure inferred from analogy.
