ABSTRACT:
A laser mark is inscribed on an IC component, which character stroke consists of a plurality of laser paths inscribed by a laser beam. The width of the character stroke is greater than the widths of the laser paths. In addition, at least two of the laser paths, moving in opposite directions or in a same direction of the laser beam, are integrally connected as a laser-inscribing stroke to reduce end-to-end breaks between the laser paths.
