Method for generating laser beam irradiation trajectory

Abstract

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.

However, as mentioned above, in the related art, since the spiral trajectory of the laser beam is firstly generated by CAD, and the digital information of the trajectory is provided to a controller of the laser beam irradiation device, any time only If the type of the semiconductor package to be manufactured changes, it is necessary to repeat the generation of the spiral trajectory

[0009] Therefore, since the spiral trajectory generation takes a lot of time, the productivity is low
