METHOD FOR GENERATING LASER BEAM IRRADIATION TRAJECTORY

摘要

The present invention relates to a method for generating a laser beam irradiation trajectory for processing a semiconductor package, capable of automatically, accurately and easily generating a laser beam irradiation trajectory in a mold portion of the semiconductor package during manufacture of the semiconductor package. According to the present invention, the method for generating a laser beam irradiation trajectory for a semiconductor package-processing apparatus, which irradiates a laser beam onto the mold portion of the semiconductor package along a spiral trajectory to form via holes, comprises the steps of: enabling a controller of a laser beam irradiation apparatus, in which a plurality of spiral trajectory patterns are stored by types, to select one of the spiral trajectory pattern types; inputting information on the selected spiral trajectory pattern to generate a spiral trajectory; and inputting a laser beam irradiation condition.
