In this paper, we will show the laser dicing separation trends in industry after the general acceptance of laser full cut dicing of common RFIC compound semiconductor substrates. We recognize the analogue of the semiconductor markets which already apply full backside metal cutting processes. The specific advantages of the multiple beam (MB) laser cutting are pointed out, including the laser dicing strategies that can be used to obtain the desired result. In summary, its implementation shows cycle time reduction, cost reduction, and the elimination of backside processes.
