Abstract
A method of fabricating a semiconductor wafer having an active area and an inactive outer clear out area includes the step of fabricating a number of active dies on a first side of the wafer such that each of the number of active dies is completely contained within the active area of the wafer. The method also includes the step of generating a laser beam with a laser device. Moreover, the method includes the step of scribing a code in the inactive outer clear out area of the wafer with the laser beam such that the code is completely contained within the inactive outer clear out area of the wafer. An apparatus for scribing a code in an inactive outer clear out area of a first side of a semiconductor wafer is also disclosed.
