Abstract
A method for separating individual optoelectronic devices, such as LEDs, from a wafer includes directing a laser beam having a width toward a major surface of the semiconductor wafer. The laser beam has an image with a first portion of a first energy per unit width and a second portion of a second energy per unit width less than the first energy. The laser beam image cuts into the first major surface of the semiconductor wafer to produce individual devices.
