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.
Claims11
An IC component having a laser mark including a character, the character having at least a character stroke consisting of a plurality of laser paths inscribed on a surface of the IC component by a laser beam, wherein the width of the character stroke is greater than the widths of the laser paths, wherein at least two of the plurality of laser paths are integrally connected as a laser-inscribing stroke to reduce end-to-end breaks between the laser paths, wherein the laser-inscribing stroke has only two independent terminals which are separated by at least one of the laser paths without crossing of the laser paths.
