Abstract
An improved method for singulation of compound electronic devices is presented. Compound electronic devices are manufactured by combining two or more substrates into an assembly containing multiple devices. Presented are methods for singulation of compound electronic devices using laser processing. The methods presented provide fewer defects such as cracking or chipping of the substrates while minimizing the width of the kerf and maintaining system throughput.
